Lee Jones c94a4ab7af ARM: ux500: Disable the MMCI gpio-regulator by default
Not all supported boards will require a MMCI gpio-regulator,
therefore it's a good idea to only enable the node when and if
it is required. Let's disable it by default.

H. Peter Anvin cb7cb2864e x86, kvm: Remove incorrect redundant assembly constraint
In __emulate_1op_rax_rdx, we use "+a" and "+d" which are input/output
constraints, and *then* use "a" and "d" as input constraints.  This is
incorrect, but happens to work on some versions of gcc.

However, it breaks gcc with -O0 and icc, and may break on future
versions of gcc.

Suresh Siddha 29c574c0ab x86, apic: Cleanup cfg->domain setup for legacy interrupts
Issues that need to be handled:
* Handle PIC interrupts on any CPU irrespective of the apic mode
* In the apic lowest priority logical flat delivery mode, be prepared to
  handle the interrupt on any CPU irrespective of what the IO-APIC RTE says.
* Because of above, when the IO-APIC starts handling the legacy PIC interrupt,
  use the same vector that is being used by the PIC while programming the
  corresponding IO-APIC RTE.

Start with all the cpu's in the legacy PIC interrupts cfg->domain.

By the time IO-APIC starts taking over the PIC interrupts, apic driver
model is finalized. So depend on the assign_irq_vector() to update the
cfg->domain and retain the same vector that was used by PIC before.

For the logical apic flat mode, cfg->domain is updated (during the first
call to assign_irq_vector()) to contain all the possible online cpu's (0xff).
Vector used for the legacy PIC interrupt doesn't change when the IO-APIC
starts handling the interrupt. Any interrupt migration after that
doesn't change the cfg->domain or the vector used.

For other apic modes like physical mode, cfg->domain is updated
(during the first call to assign_irq_vector()) to the boot cpu (cpu-0),
with the same vector that is being used by the PIC. When that interrupt is
migrated to a different cpu, cfg->domin and the vector assigned will change
accordingly.

Mark Salter 9c0603f487 c6x: fix misleading comment
A comment in entry.S incorrectly stated that interrupt vectors
called __do_IRQ() and that int6 vector was used for syscalls.
Both statements are incorrect for the current kernel, so this
patch cleans up the wording to reflect current reality.

   when booting from device tree.
 - Group all devices on the SoC below this bus so as to
   set a good example of how to do this. The bus was
   invented by Lee Jones, let's show how it's to be used
   on a DT:ed SoC.
 - Fetch the special system controller offsets from two
   special device tree nodes for each case and replace
   the static mappings with these at boot.
 - Move some static remaps to the ATAG-only code path
   and delete some static maps that aren't used.
 - Push dependencies on system controller remaps down
   to the Integrator/AP board file and the PCIv3 driver
   respectively and use only dynamic remappings.
 - Fix up conditional BUG() usage in the PCIv3 driver
   to be simpler and more to the point.

Linus Torvalds c2a65d3d85 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
 "Three issues fixed accross the field:

   - Some functions that were recently outlined as part of a preemption
     fix were causing problems with function tracing.
   - The recently merged in-kernel MPI library uses very outdated
     headers that contain MIPS-specific code which won't build on with
     gcc 4.4 or newer.
   - The MIPS non-NUMA memory initialization was making only a very
     half-baked attempt at merging adjacent memory ranges.  This kept
     the code simple enough but is now causing issues with kexec."

  MPI: Fix compilation on MIPS with GCC 4.4 and newer

Gavin Shan e716e01438 powerpc/eeh: Do not invalidate PE properly
While the EEH does recovery on the specific PE that has PCI errors,
the PCI devices belonging to the PE will be removed and the PE will
be marked as invalid since we still need the information stored in
the PE. We only invalidate the PE when it doesn't have associated
EEH devices and valid child PEs. However, the code used to check
that is wrong. The patch fixes that.

and D-Link seem to specify 30us in their kernels for both devices.
Increase to 35us to make sure the NAND is stable.

Andreas Larsson 0e622d3919 of/address: sparc: Declare of_iomap as an extern function for sparc again
This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.

The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.

This fix takes the same approach as 0bce04b that solved the equivalent problem
for of_address_to_resource.

Will Deacon 304ef4e836 arm64: signal: push the unwinding prologue on the signal stack
To allow debuggers to unwind through signal frames, we create a fake
stack unwinding prologue containing the link register and frame pointer
of the interrupted context. The signal frame is then offset by 16 bytes
to make room for the two saved registers which are pushed onto the frame
of the *interrupted* context, rather than placed directly above the
signal stack.

This doesn't work when an alternative signal stack is set up for a SEGV
handler, which is raised in response to RLIMIT_STACK being reached. In
this case, we try to push the unwinding prologue onto the full stack and
subsequently take a fault which we fail to resolve, causing setup_return
to return -EFAULT and handle_signal to force_sigsegv on the current task.

This patch fixes the problem by including the unwinding prologue as part
of the rt_sigframe definition, which is populated during setup_sigframe,
ensuring that it always ends up on the signal stack.

Dave Martin 5010192d5a ARM: 7583/1: decompressor: Enable unaligned memory access for v6 and above
Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

If a kernel is configured with a DT containing more /cpu nodes than
nr_cpu_ids, the number of cpus must be capped in the DT parsing
code. Current code carries out the check, but fails to cap the
value and the check is executed after the cpu logical index is used,
which can lead to memory corruption due to index overflow.

This patch refactors the check against nr_cpu_ids and move it before
any computed index is used in the parsing code.

In other words, rt_sigprocmask(69, (void *)69, 69) done by 32bit process
will promptly panic the box.

Arnd Bergmann 0d2c9f0517 IXP4xx: use __iomem for MMIO
The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the
type for a pointer that is passed to __raw_writel, which is not
allowed because of the const-ness.

Dropping the 'const' keyword fixes the problem. While we're here,
let's also drop the useless type cast.

Without this patch, building ixp4xx_defconfig results in:

Peter Ujfalusi c567b0584c ARM: OMAP2+: omap_device: Correct resource handling for DT boot
When booting with DT the OF core can fill up the resources provided within
the DT blob.
The current way of handling the DT boot prevents us from removing hwmod data
for platforms only suppose to boot with DT (OMAP5 for example) since we need
to keep the whole hwmod database intact in order to have more resources in
hwmod than in DT (to be able to append the DMA resource from hwmod).

To fix this issue we just examine the OF provided resources:
If we do not have resources we use hwmod to fill them.
If we have resources we check if we already able to recive DMA resource, if
no we only append the DMA resurce from hwmod to the OF provided ones.

In this way we can start removing hwmod data for devices which have their
resources correctly configured in DT without regressions.

Igor Grinberg 0a0d628573 ARM - OMAP: ads7846: fix pendown debounce setting
Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

Correct. I did the conversion and tested that the partitions
can be read with dd and produce exactly the same data before and
after conversion. So, the partition offsets at least should be fine.

Ok, I did convert the i2c definition to use the devicetree.
The adt7476 device itself is not at reach of device tree,
AFAIK and requires more work at there?

Thanks for your valuable comments. Following is a new patch that
should address the problems and mistakes you pointed and also
some of the pointed by Jason Cooper. The nand and i2c are now
defined at DT and I also removed the pointless defines and
ARM_APPENDED_DTB. It is based against the Linus' official
3.6 version.

Fix the condition.  (It may have been less likely to occur had the code
been written "if (irq >= IRQ_DOVE_PMU_START" which imho is the easier
to understand notation, and matches the normal way of thinking about

Russell King - ARM Linux 5d3df93542 Dove: Attempt to fix PMU/RTC interrupts
Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner.  The PMU is one such instance.

The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)

Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed.  If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing.  So, we need to do a read-modify-write
cycle to clear the asserted bit.

However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.

The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.)  The patch below at least stops us creating
new interrupts.

Igor Grinberg 6f80b3bb8a ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER
CONFIG_OMAP_32K_TIMER is kind of standing on the single zImage way.
Make OMAP2+ timer code independant from the CONFIG_OMAP_32K_TIMER
setting.
To remove the dependancy, several conversions/additions had to be done:
1) Timer initialization functions are named by the platform
   name and the clock source in use.
   This also makes it possible to define and use the GPTIMER as the
   clock source instead of the 32K timer on platforms that do not have
   the 32K timer ip block or the 32K timer is not wired on the board.
   Currently, the the timer is chosen in the machine_desc structure on
   per board basis. Later, DT should be used to choose the timer.
2) Settings under the CONFIG_OMAP_32K_TIMER option are used as defaults
   and those under !CONFIG_OMAP_32K_TIMER are removed.
   This removes the CONFIG_OMAP_32K_TIMER on OMAP2+ timer code.
3) Since we have all the timers defined inside machine_desc structure
   and we no longer need the fallback to gp_timer clock source in case
   32k_timer clock source is unavailable (namely on AM33xx), we no
   longer need the #ifdef around omap2_sync32k_clocksource_init()
   function. Remove the #ifdef CONFIG_OMAP_32K_TIMER around the
   omap2_sync32k_clocksource_init() function.

This is needed at least on Origen board for sdhci2 to work and
if any other drive strength is required on each board, we can

A device can be bound to particular power domain by adding a

 Many of the changes simply remove useless #include statements, which

In order to cover the full code ranges, the CFI directive must be

Robert Richter 1022623842 x86-32: Fix invalid stack address while in softirq
In 32 bit the stack address provided by kernel_stack_pointer() may
point to an invalid range causing NULL pointer access or page faults
while in NMI (see trace below). This happens if called in softirq
context and if the stack is empty. The address at &regs->sp is then
out of range.

Fixing this by checking if regs and &regs->sp are in the same stack
context. Otherwise return the previous stack pointer stored in struct
thread_info. If that address is invalid too, return address of regs.

Doug Anderson 95e82941b7 ARM: dts: Add board dts file for Snow board (ARM Chromebook)
This dts file is based on the Snow dts file in the Chromium OS kernel
tree with the following changes:
* Some details have been updated to match the exynos5250-smdk5250.dts
  file from linux-next (as of c11068538994430547722dc9fb515a0ceefd5cb9).
* This file doesn't include references to hardware whose upstream
  support isn't quite there yet.  That includes most i2c devices.
  Note that most i2c busses have been included with no devices.

The Snow dts file is mostly just an include of the "cros5250" dts file
which describes a class of similar boards. Support for other boards has
not yet been send upstream.

With this file and a change to use UART3 for serial output I can:
* Boot to a command line using either SD or EMMC as a root filesystem
* See the power button and lid switch using evtest.

Anatolij 52xx updates:

Patch for pcm030 device tree fixing the probe() in pcm030-audio-fabric
driver. Changes to this driver have been merged in 3.7-rc1 via ASoC
tree, but this required device tree patch was submitted separately to
the linux-ppc list and is still missing in mainline. Without this patch
the probe() in pcm030-audio-fabric driver wrongly returns -ENODEV.

A patch from Wolfram fixing wrong invalid critical irq warnings for
all mpc5200 boards.

Another patch for all mpc5200 device trees fixing wrong L1 cell in
the LPB FIFO interrupt property and moving the LPB FIFO node to the
common mpc5200b.dtsi file so that this common node will be present
in all mpc5200 device trees.

Matt Fleming 0f905a43ce x86, efi: Fix processor-specific memcpy() build error
Building for Athlon/Duron/K7 results in the following build error,

arch/x86/boot/compressed/eboot.o: In function `__constant_memcpy3d':
eboot.c:(.text+0x385): undefined reference to `_mmx_memcpy'
arch/x86/boot/compressed/eboot.o: In function `efi_main':
eboot.c:(.text+0x1a22): undefined reference to `_mmx_memcpy'

because the boot stub code doesn't link with the kernel proper, and
therefore doesn't have access to the 3DNow version of memcpy. So,
follow the example of misc.c and #undef memcpy so that we use the
version provided by misc.c.

Christian Daudt 8ac49e0485 Add support for generic BCM SoC chipsets
In order to start upstreaming Broadcom SoC support, create
a starting hierarchy, arch and dts files.
The first support SoC family that is planned is the
BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile
SoC cores.
This code is just the skeleton code for get the machine upstreamed. It
has been made MULTIPLATFORM compatible.
Next steps
----------
Upstream a basic set of drivers - sufficient for a console boot to
ramdisk. These will includer timer, gpio, i2c drivers.
After this basic set, we will proceed with a more comprehensive set
of drivers for the 281XX SoC family.

v2 patch mods
--------
 - Remove l2x0_of_init call as there were problems with the code.
   A separate patch will be submitted with cache init code
 - Rename capri files and refs to bcm281xx-based names
 - Add bcm281xx binding doc
 - various misc cleanups

v3 patch mods
-------------
 - Remove extra #include lines
 - Remove remaining references to capri
 - dt uart chipset string added
 - cleaned up chip # references

v4 patch mods
-------------
 - swap order of compatible definitions for uart
 - fix typo

v5 patch mods
-------------
 - Rename bcm281xx to bcm11351 in dts+code,
   leaving references to bcm281xx only in help+comments.

v6 patch mods
-------------
 - fix typo in uart 'compatible' string

Nicolas Pitre 384a290283 ARM: gic: use a private mapping for CPU target interfaces
The GIC interface numbering does not necessarily follow the logical
CPU numbering, especially for complex topologies such as multi-cluster
systems.

Fortunately we can easily probe the GIC to create a mapping as the
Interrupt Processor Targets Registers for the first 32 interrupts are
read-only, and each field returns a value that always corresponds to
the processor reading the register.

Initially all mappings target all CPUs in case an IPI is required to
boot secondary CPUs.  It is refined as those CPUs discover what their
actual mapping is.

Lorenzo Pieralisi 7f124aaf01 ARM: kernel: add logical mappings look-up
In ARM SMP systems the MPIDR register ([23:0] bits) is used to uniquely
identify CPUs.

In order to retrieve the logical CPU index corresponding to a given
MPIDR value and guarantee a consistent translation throughout the kernel,
this patch adds a look-up based on the MPIDR[23:0] so that kernel subsystems
can use it whenever the logical cpu index corresponding to a given MPIDR
value is needed.

Lorenzo Pieralisi 5587164eea ARM: kernel: add cpu logical map DT init in setup_arch
As soon as the device tree is unflattened the cpu logical to physical
mapping is carried out in setup_arch to build a proper array of MPIDR and
corresponding logical indexes.

The mapping could have been carried out using the flattened DT blob and
related primitives, but since the mapping is not needed by early boot
code it can safely be executed when the device tree has been uncompressed to
its tree data structure.

This patch adds the arm_dt_init_cpu maps() function call in setup_arch().

If the kernel is not compiled with DT support the function is empty and
no logical mapping takes place through it; the mapping carried out in
smp_setup_processor_id() is left unchanged.
If DT is supported the mapping created in smp_setup_processor_id() is overriden.
The DT mapping also sets the possible cpus mask, hence platform
code need not set it again in the respective smp_init_cpus() functions.

Lorenzo Pieralisi a0ae024050 ARM: kernel: add device tree init map function
When booting through a device tree, the kernel cpu logical id map can be
initialized using device tree data passed by FW or through an embedded blob.

This patch adds a function that parses device tree "cpu" nodes and
retrieves the corresponding CPUs hardware identifiers (MPIDR).
It sets the possible cpus and the cpu logical map values according to
the number of CPUs defined in the device tree and respective properties.

The device tree HW identifiers are considered valid if all CPU nodes contain
a "reg" property, there are no duplicate "reg" entries and the DT defines a
CPU node whose "reg" property matches the MPIDR[23:0] of the boot CPU.

The primary CPU is assigned cpu logical number 0 to keep the current convention
valid.

Current bindings documentation is included in the patch:

Lorenzo Pieralisi b4b8f770eb ARM: kernel: update cpuinfo to print all online CPUs features
Currently, reading /proc/cpuinfo provides userspace with CPU ID of
the CPU carrying out the read from the file. This is fine as long as all
CPUs in the system are the same. With the advent of big.LITTLE and
heterogenous ARM systems this approach provides user space with incorrect
bits of information since CPU ids in the system might differ from the one
provided by the CPU reading the file.

This patch updates the cpuinfo show function so that a read from
/proc/cpuinfo prints HW information for all online CPUs at once, mirroring
 x86 behaviour.

Kees Cook ad75b51459 ARM: 7579/1: arch/allow a scno of -1 to not cause a SIGILL
On tracehook-friendly platforms, a system call number of -1 falls
through without running much code or taking much action.

ARM is different. This adds a short-circuit check in the trace path to
avoid any additional work, as suggested by Russell King, to make sure
that ARM behaves the same way as other platforms.

Kees Cook 9b790d71d5 ARM: 7578/1: arch/move secure_computing into trace
There is very little difference in the TIF_SECCOMP and TIF_SYSCALL_WORK
path in entry-common.S, so merge TIF_SECCOMP into TIF_SYSCALL_WORK and
move seccomp into the syscall_trace_enter() handler.

Expanded some of the tracehook logic into the callers to make this code
more readable. Since tracehook needs to do register changing, this portion
is best left in its own function instead of copy/pasting into the callers.

Additionally, the return value for secure_computing() is now checked
and a -1 value will result in the system call being skipped.

Lad, Prabhakar e37212aa5d ARM: davinci: dm644x: fix out range signal for ED
Fix the video clock setting when custom timings are used with
pclock <= 27MHz. Existing video clock selection uses PLL2 mode
which results in a 54MHz clock whereas using the MXI mode results
in a 27MHz clock (which is the one actually desired).

This bug affects the Enhanced Definition (ED) support on DM644x.
Without this patch, out-range signals errors are were observed on
the TV when viewing ED. An out-of-range signal is often caused when
the field rate is above the rate that the television will handle.

Al Viro fae2ae2a90 sparc64: not any error from do_sigaltstack() should fail rt_sigreturn()
If a signal handler is executed on altstack and another signal comes,
we will end up with rt_sigreturn() on return from the second handler
getting -EPERM from do_sigaltstack().  It's perfectly OK, since we
are not asking to change the settings; in fact, they couldn't have been
changed during the second handler execution exactly because we'd been
on altstack all along.  64bit sigreturn on sparc treats any error from
do_sigaltstack() as "SIGSEGV now"; we need to switch to the same semantics
we are using on other architectures.
