flush_cache_louis flushes the D-side caches to the point of unification
inner-shareable. On uniprocessor CPUs, this is defined as zero and
therefore no flushing will take place. Rather than invent a new interface
for UP systems, instead use our SMP_ON_UP patching code to read the
LoUU from the CLIDR instead.

find_vma() is *not* safe when somebody else is removing vmas. Not just
the return value might get bogus just as you are getting it (this instance
doesn't try to dereference the resulting vma), the search itself can get
buggered in rather spectacular ways. IOW, ->mmap_sem really, really is
not optional here.

All architectures have
CONFIG_GENERIC_KERNEL_THREAD
CONFIG_GENERIC_KERNEL_EXECVE
__ARCH_WANT_SYS_EXECVE
None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers
of kernel_execve() (which is a trivial wrapper for do_execve() now) left.
Kill the conditionals and make both callers use do_execve().

I2S controller has an internal mux for RCLK source clks. The list
of source clk names were passed through platform data in non-dt case.
The variable holding the list of RCLK source clk names is not
required, as the list of clks need to be registered with clkdev
using generic connection id. This is required as part of adding DT

Since udev-182, udev no longer creates device nodes under /dev
and this has to be managed by the kernel devtmpfs filesystem.
This means that a kernel built with the current OMAP2+ config
will not boot on a system with a recent udev.
Also, it is good to have /dev automatically mounted since some
non-initramfs based setups assumes this and don't manually mount it.

We want to limit cpu_is_omap macro usage to mach-omap2 only so

There is several different SoCs sharing the sun5i codename: A10s, A12
and A13. Since there is enough differences to not consider those the
same SoCs, change a bit the naming scheme to reflect this.
Moreover, some boards like the olinuxino come in A10s and A13 variants,
which also share the same SoC codename.
So change the naming scheme to reflect both the codename and the market
name of the SoCs used in the dtsi and in the board files

The MIPI/HSP clocks were recently turned on in the i.MX51 clock tree.
It turned out that the system does not work properly when the MIPI/HSP
clocks are enabled, but the IPU clock is disabled. This happens when
IPU support is disabled. In this case the IPU clock gets disabled when
the clock framework turns off unused clock in a late_initcall. This
is broken since:
| commit 9a2d4825a9
| Author: Sascha Hauer <s.hauer@pengutronix.de>
| Date: Tue Jun 5 13:53:32 2012 +0200
|
| ARM i.MX5: switch IPU clk support to devicetree bindings
|
| The i.MX5 clk support has platform based clock bindings for the
| IPU. IPU support is devicetree only, so move them over to devicetree
| based bindings. Also, enable MIPI clocks which do not have a device
| associated with, but still need to be enabled to do graphics on
| i.MX51.
This patch fixes this by setting some reserved bits in the CCM as recommended
in the reference manual.

The .notes, being read-only data by nature, were placed between
read-write .data and .bss. This was harmful in case of the XIP
kernel, as being placed in the RAM range, most likely far
from the ROM address, was inflating the XIP images.
Moving the .notes at the end of the read-only section
(consisting of .text, .rodata and unwind info) fixes the problem.

The OMAP4 clock divider "div_iva_hs_clk" is listed in the clock data
as an OMAP HSDIVIDER, but it's actually a power-of-two divider. This
causes a warning during boot on an OMAP4460 Pandaboard-ES with a
recent u-boot:
WARNING: at arch/arm/mach-omap2/clkt_clksel.c:143 omap2_clksel_recalc+0xf4/0x12c()

Commit d043d87 (ARM: OMAP2+: clockdomain: bypass clockdomain handling
when disabling unused clks) skips the decrementing of a clock-domains
use count if the clocks use count is zero. However, for OMAP4 devices
this is causing the EMU clock-domain to be stuck ON as the use count is
not getting decremented correctly.
The scenario that leads to this problem is described below ...
omap_hwmod_setup_all
--> _setup
--> clkdm_hwmod_enable
--> EMU clock domain usecount = 1
--> _enable_clocks
--> clk_enable
--> trace_clk_div_div usecount = 1
--> clkdm_hwmod_enable
--> EMU clock domain usecount = 2
--> _idle
--> _disable_clocks
--> clk_disable
--> trace_clk_div_div usecount = 0
--> clkdm_hwmod_disable
--> skips decrement of EMU clock domain usecount
because trace_clk_div_div is 0!
--> EMU clock domain usecount = 2
--> clkdm_hwmod_disable
--> EMU clock domain usecount = 1
Hence, due to the order that a clocks use count is decremented and the
clock domain is disabled, it is possible that the clock domain can have
a non-zero use count when the actual clock has a use count of 0.
Therefore, we should only bypass the clock-domain handling when both the
clock-domain and clock in the clock-domain have a use count of 0 and
warn when the clock-domain has a zero use count and the clock has a
non-zero use count.

With the latest mainline u-boot bootloader (v2012.10), timers (5-8) in
the ABE power domain are failing to turn-on. The timers never come out
of the disabled state when setting the module-mode field to enable.
The problem was exposed when u-boot was updated to NOT configure and
lock the ABE DPLL on start-up. If the ABE DPLL is configured and locked
by u-boot the problem does not occur. However, if the ABE DPLL is in the
idle low-power bypass state and we attempt to enable a timer in the ABE
power domain, it remains stuck in the disabled state. It appears to be a
problem the timer interface clock as this comes from the ABE DPLL.
If we place the ABE DPLL in the MN-bypass state and not the idle
low-power state, then this problem is not seen.
This problem only appears to occur on OMAP4460 and not OMAP4430.
Workaround this problem by locking the ABE DPLL for OMAP4460 in the
kernel on boot. By locking the ABE DPLL, when clocks from the ABE DPLL
are not being requested the DPLL will transition into a low-power stop
mode.

On OMAP4 devices, the ABE DPLL has an internal 4X multiplier that can
be enabled or disabled in addition to the standard configurable
multiplier (M) for OMAP DPLLs. When configuring the ABE DPLL the 4X
multiplier is accounted for by checking to see whether it is enabled or
not. However, when calculating a new rate we only check to see if the
rate can be achieved with the current setting for the 4X multiplier.
Enhance the round_rate() function for such DPLLs to see if the rate
can be achieved with the 4X multiplier if it cannot be achieved without
the 4X multiplier.
This change is necessary, because when using the 32kHz clock as the
source clock for the ABE DPLL, the default DPLL frequency for the ABE
DPLL cannot be achieved without enabling the 4X multiplier.
When using the 32kHz clock as the source clock for the ABE DPLL and
attempting to lock the DPLL to 98.304MHz (default frequency), it was
found that the DPLL would fail to lock if the low-power mode for the DPLL
was not enabled. From reviewing boot-loader settings that configure the
ABE DPLL it was found that the low-power mode is enabled when using the
32kHz clock source, however, the documentation for OMAP does not state
that this is a requirement. Therefore, introduce a new function for
OMAP4 devices to see if low-power mode can be enabled when calculating a
new rate to ensure the DPLL will lock.
New variables for the last calculated 4X multiplier and low-power
setting have been added to the dpll data structure as well as variables
defining the bit mask for enabling these features via the DPLL's
control_reg. It is possible that we could eliminate these bit masks from
the dpll data structure as these bit masks are not unique to OMAP4, if
it is preferred.
The function omap3_noncore_program_dpll() has been updated to avoid
passing the calculated values for the multiplier (M) and divider (N) as
these are stored in the clk structure.

Currently all OMAP4 non-core DPLLs use the same function table for
configuring DPLLs. For these DPLLs, the function
omap4_dpll_regm4xen_recalc() is used to recalculate the DPLL rate and
the function omap4_dpll_regm4xen_round_rate() is used to calculate the
closest rate to that requested. However, these omap4_dpll_regm4xen_xxx()
functions are only applicable to the ABE DPLL and not the other non-core
DPLLs. Therefore, add a new function table for non-core DPLLs that do
not include the 4X-multiplier (M4X).
Please note that using these omap4_dpll_regm4x_xxx() function works for
the non-M4X DPLLs today because we only check to see if the 4X
multiplier is enabled when calculating the rate. However, it is planned
that the dpll functions will be enhanced to enable the 4X multiplier as
necessary (in order to achieve the requested rate) and so calling these
functions for non-M4X dplls will no longer work.

Commit "ARM: dts: OMAP4: Update timer addresses" updated the device-tree
names of the OMAP4 timers 5-7 because the default address for the timers
was changed from the L3 address to the MPU private address. When booting
with device-tree, this introduces a regression when attempting to set
the parent clock of timers 5-7 to the sys_clk_div_ck. Therefore, update
the clock aliases for timer 5-7 to reflect the updated device-tree name

The i2c handling in tfp410 driver, which handles converting parallel RGB
to DVI, was changed in 958f2717b8
(OMAPDSS: TFP410: pdata rewrite). The patch changed what value the
driver considers as invalid/undefined. Before the patch, 0 was the
invalid value, but as 0 is a valid bus number, the patch changed this to
-1.
However, the fact was missed that many board files do not define the bus
number at all, thus it's left to 0. This causes the driver to fail to
get the i2c bus, exiting from the driver's probe with an error, meaning
that the DVI output does not work for those boards.
This patch fixes the issue by changing the i2c_bus number field in the
driver's platform data from u16 to int, and setting the bus number to -1
in the board files for the boards that did not define the bus. The
exception is devkit8000, for which the bus is set to 1, which is the
correct bus for that board.
The bug exists in v3.5+ kernels.

Merge tag 'for-v3.8-merged' of git://git.infradead.org/battery-2.6
Pull battery subsystem updates from Anton Vorontsov:
"Highlights:
- Two new drivers from Pali Rohár and N900 hackers: rx51_battery and
bq2415x_charger. The drivers are a part of a solution to replace
the proprietary Nokia BME stack
- Power supply core now registers devices with a thermal cooling
subsystem, so we can now automatically throttle charging. Thanks
to Ramakrishna Pallala!
- Device tree support for ab8500 and max8925_power drivers

It includes a split-up of some of the OMAP clock data into separate
files which adds to the diffstat, but gross delta is fairly reasonable.

Continued device tree conversion and enablement across a number of

smaller series as well.
ux500 has seen continued conversion for platforms. Several platforms have
seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
is adding data for new devices/drivers, and Exynos has a bunch of new
bindings and devices added as well.
So, pretty much the same progression in the right direction as the last
few releases.

Pull ARM SoC device tree conversions and enablement from Olof Johansson:
"Continued device tree conversion and enablement across a number of
platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
smaller series as well.
ux500 has seen continued conversion for platforms. Several platforms
have seen pinctrl-via-devicetree conversions for simpler
multiplatform. Tegra is adding data for new devices/drivers, and
Exynos has a bunch of new bindings and devices added as well.
So, pretty much the same progression in the right direction as the
last few releases."

Pull big execve/kernel_thread/fork unification series from Al Viro:
"All architectures are converted to new model. Quite a bit of that
stuff is actually shared with architecture trees; in such cases it's
literally shared branch pulled by both, not a cherry-pick.
A lot of ugliness and black magic is gone (-3KLoC total in this one):
- kernel_thread()/kernel_execve()/sys_execve() redesign.
We don't do syscalls from kernel anymore for either kernel_thread()
or kernel_execve():
kernel_thread() is essentially clone(2) with callback run before we
return to userland, the callbacks either never return or do
successful do_execve() before returning.
kernel_execve() is a wrapper for do_execve() - it doesn't need to
do transition to user mode anymore.
As a result kernel_thread() and kernel_execve() are
arch-independent now - they live in kernel/fork.c and fs/exec.c
resp. sys_execve() is also in fs/exec.c and it's completely
architecture-independent.
- daemonize() is gone, along with its parts in fs/*.c
- struct pt_regs * is no longer passed to do_fork/copy_process/
copy_thread/do_execve/search_binary_handler/->load_binary/do_coredump.
- sys_fork()/sys_vfork()/sys_clone() unified; some architectures
still need wrappers (ones with callee-saved registers not saved in
pt_regs on syscall entry), but the main part of those suckers is in
kernel/fork.c now."

Two new platforms have been added, the sunxi platforms (Allwinner A1x
SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
series of ARMv7 platforms from them, where the hope is that we can
keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms.

There's a bunch of patch series from Will tackling various bugs like
the PROT_NONE handling, ASID allocation, cluster boot protocol and
ASID TLB tagging updates.
We move to a build-time sorted exception table rather than doing the
sorting at run-time, add support for the secure computing filter, and
some updates to the perf code. We also have sorted out the placement
of some headers, fixed some build warnings, fixed some hotplug

Pull ARM OMAP serial updates from Russell King:
"This series is a major reworking of the OMAP serial driver code fixing
various bugs in the hardware-assisted flow control, extending up into
serial_core for a couple of issues. These fixes have been done as a
set of progressive changes and transformations in the hope that no new
bugs will be introduced by this series.
The problems are many-fold, from the driver not being informed about
updated settings, to the driver not knowing what the intentions of the
upper layers are.
The first four patches tackle the serial_core layer, allowing it to
provide the necessary information to drivers, and the remaining
patches allow the OMAP serial driver to take advantage of this.
This brings hardware assisted RTS/CTS and XON/OFF flow control into a
useful state.
These patches have been in linux-next for most of the last cycle;
indeed they predate the previous merge window. They've also been
posted to the OMAP people."

* ftrace enhancements and fixes from Steve Rostedt.
* uprobes fixes, cleanups and preparation for the ARM port from Oleg
Nesterov.
* UAPI fixes, from David Howels - prepares the arch/x86 UAPI
transition
* Separate perf tests into multiple objects, one per test, from Jiri

Olsa.
* Fixes to /proc/pid/maps parsing, preparatory to supporting data
maps, from Namhyung Kim
* Implement ui_progress for GTK, from Namhyung Kim
* Add framework for automated perf_event_attr tests, where tools with
different command line options will be run from a 'perf test', via
python glue, and the perf syscall will be intercepted to verify
that the perf_event_attr fields set by the tool are those expected,
from Jiri Olsa
* Add a 'link' method for hists, so that we can have the leader with
buckets for all the entries in all the hists. This new method is
now used in the default 'diff' output, making the sum of the
'baseline' column be 100%, eliminating blind spots.
* libtraceevent fixes for compiler warnings trying to make perf it
build on some distros, like fedora 14, 32-bit, some of the warnings
really pointed to real bugs.
* Add a browser for 'perf script' and make it available from the
report and annotate browsers. It does filtering to find the
scripts that handle events found in the perf.data file used. From
Feng Tang
* perf inject changes to allow showing where a task sleeps, from
Andrew Vagin.
* Makefile improvements from Namhyung Kim.
* Add --pre and --post command hooks in 'stat', from Peter Zijlstra.
* Don't stop synthesizing threads when one vanishes, this is for the
existing threads when we start a tool like trace.
* Use sched:sched_stat_runtime to provide a thread summary, this
produces the same output as the 'trace summary' subcommand of
tglx's original "trace" tool.
* Support interrupted syscalls in 'trace'
* Add an event duration column and filter in 'trace'.
* There are references to the man pages in some tools, so try to
build Documentation when installing, warning the user if that is
not possible, from Borislav Petkov.
* Give user better message if precise is not supported, from David
Ahern.
* Try to find cross-built objdump path by using the session

Tirdea, original patch and idea by Namhyung Kim.
* Diplays more output on features check for make V=1, so that one can
figure out what is happening by looking at gcc output, etc. From
Jiri Olsa.
* Add on_exit implementation for systems without one, e.g. Android,
from Bernhard Rosenkraenzer.
* Only process events for vcpus of interest, helps handling large
number of events, from David Ahern.

This patch changes the busy-waiting loop around in the decompressor
putc() function on the UART FIFO register. Without a proper wait, the
output of the decompressor was corrupted like this:
Uncompressing Linx. done, booting th enl
To highlight the issue more evidently, looping 100 times instead of 1000
makes the issue appear much faster. This patch takes the approach of
using an active while loop until the FIFO is empty (not FULL).
This issue happened to me on Sim.One running at 200Mhz.

Here's the big set of USB patches for 3.8-rc1.
Lots of USB host driver cleanups in here, and a bit of a reorg of the
EHCI driver to make it easier for the different EHCI platform drivers to
all work together nicer, which was a reduction in overall code. We also
deleted some unused firmware files, and got rid of the very old
file_storage usb gadget driver that had been broken for a long time.
This means we ended up removing way more code than added, always a nice

Here is the "big" char/misc driver patches for 3.8-rc1. I'm starting to

Nothing major here, the various __dev* removals, some mei driver

Note, some MFD drivers got added through this tree, and they are also
coming in through the "real" MFD tree as well, due to some major
mis-communication between me and the different developers. If you have
any merge conflicts, take the ones from the MFD tree, not these ones,
sorry about that.

updates, and other random driver-specific things from the different
maintainers and developers.
Note, some MFD drivers got added through this tree, and they are also
coming in through the "real" MFD tree as well, due to some major
mis-communication between me and the different developers. If you
have any merge conflicts, take the ones from the MFD tree, not these
ones, sorry about that.
All of this has been in linux-next for a while.

- Some local movement in the Marvell MVEBU drivers,
these now have their own subdirectory.
- The addition of a chunk of code to gpiolib under

The REALVIEW EB board can host tiles with multiple cores thus needs
to be able to initialise SMP. There is, however, no .smp entry in
the MACHINE_START struct for REALVIEW_EB.
This patch adds the appropriate .smp entry to this struct.

The kernel can only be entered on HYP mode on CPUs which actually
support it, i.e. >= ARMv7. pre-v6 platform support cannot coexist
in the same kernel as support for v7 and higher, so there is no
advantage in having the HYP mode check on pre-v6 hardware.
At least one pre-v6 board is known to fail when the HYP mode check
code is present, although the exact cause remains unknown and may
be unrelated. [1]
This patch restores the old behaviour for pre-v6 platforms, whereby
the CPSR is forced directly to SVC mode with IRQs and FIQs masked.
All kernels capable of booting on v7 hardware will retain the
check, so this should not impair functionality.

The offset must be multiplied by 4 to be sure to access the correct

For instance, a store at scratch memory cell #1 was generating the
following:

While the correct code for this is:
st r4, [sp, #4]
To reproduce the bug (assuming your system has a NIC with the mac

tcpdump -ni eth0 "ether[1] + ether[2] - ether[3] * ether[4] - ether[5] \

syscall_trace_exit is currently doing things back-to-front; invoking
the audit hook *after* signalling the debugger, which presents an
opportunity for the registers to be re-written by userspace in order to
bypass auditing constaints.
This patch fixes the ordering by moving the audit code first and the
tracehook code last. On the face of it, it looks like
current_thread_info()->syscall may be incorrect for the sys_exit
tracepoint, but that's actually not an issue because it will have been
set during syscall entry and cannot have changed since then.

Official prototype for kzalloc is:

The ARM bpf_jit code was having the assumption that it was:
void *kzalloc(gfp_t, size);
This was resulting the use of some random GFP flags depending on the
size requested and some random overflows once the really needed size
was more than the value of GFP_KERNEL.

Commit b9a50f7490 ("ARM: 7450/1: dcache: select DCACHE_WORD_ACCESS for
little-endian ARMv6+ CPUs") added support for word-at-time path
comparisons, relying on the ability to perform unaligned loads with
negligible performance impact in hardware.
For nommu configurations without MPU support, this is unpredictable and
so we should fall back to the byte-by-byte routines.

Recent ARMv7 toolchains assume that unaligned memory accesses will not
fault and will instead be handled by the processor.
For the nommu case (without an MPU), memory will be treated as
strongly-ordered and therefore unaligned accesses may fault regardless
of the SCTLR.A setting.
This patch passes -mno-unaligned-access to GCC when compiling for nommu
targets, preventing the generation of unaligned memory access in the
kernel.

Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().
This change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

HSMMC IP on AM33xx need a special setting to handle High-speed cards.
Other platforms like TI81xx, OMAP4 may need this as-well. This depends
on the HSMMC IP timing closure done for the high speed cards.
From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation):
The MMC/SD/SDIO output signals can be driven on either falling edge or
rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows
to reach better timing performance, and thus to increase data transfer
frequency.
There are few pre-requisites for enabling the HSPE bit
- Controller should support High-Speed-Enable Bit and
- Controller should not be using DDR Mode and
- Controller should advertise that it supports High Speed in
capabilities register and
- MMC/SD clock coming out of controller > 25MHz

Use runtime PM functionality interfaced with hwmod enable/idle
functions, to replace direct clock operations and sysconfig
handling.
Due to reset sequence, pm_runtime_[get|put]_sync must be used, to
avoid possible operations with the module under reset. Because of
this and given that the driver uses spin_locks to protect their
critical sections, we must use pm_runtime_irq_safe in order for the
runtime ops to be happy, otherwise might_sleep_if checks in runtime
framework will complain.
The remaining pm_runtime out of iommu_enable and iommu_disable
corresponds to paths that can be accessed through debugfs, some of
them doesn't work if the module is not enabled first, but in future
if the mmu is idled withouth freeing, these are needed to debug.

Use the previously unused TPIDRPRW register to store percpu offsets.
TPIDRPRW is only accessible in PL1, so it can only be used in the kernel.
This replaces 2 loads with a mrc instruction for each percpu variable
access. With hackbench, the performance improvement is 1.4% on Cortex-A9
(highbank). Taking an average of 30 runs of "hackbench -l 1000" yields:
Before: 6.2191
After: 6.1348
Will Deacon reported similar delta on v6 with 11MPCore.
The asm "memory clobber" are needed here to ensure the percpu offset
gets reloaded. Testing by Will found that this would not happen in
__schedule() which is a bit of a special case as preemption is disabled
but the execution can move cores.

Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.
Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.
So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.
The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.
Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.
Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.
Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.
Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

ARM: S3C24XX: Fix potential NULL pointer dereference error

it's an obvious bug fix and a potential NULL pointer dereference, it

The recent commit "ARM: EXYNOS: add support for EXYNOS5440 SoC" broke
support for exynos5250 because of_machine_is_compatible() was used too
early in the boot process. It also probably meant that the exynos5440
failed to use the proper iotable. Switch to use
of_flat_dt_is_compatible() in both of these cases.
The failure I was seeing in exynos5250 because of this was:

The SP804 driver statically initialises the cpumask of the clock event
device to be cpu_all_mask, which is derived from the compile-time
constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
controller handling the sp804 doesn't have the irq_set_affinity callback
on the irq_chip, because the common timer code fails to identify the
device as cpu-local and ends up treating it as a broadcast device
instead.
This patch fixes the problem by using cpu_possible_mask at runtime,
which will correctly represent the possible CPUs when SMP_ON_UP is being
used.
