Ralf Baechle 68b6352cdc MIPS: Oprofile: Fix build as a module.
When building oprofile as a module for R10000 or R7000 class processors,
E9000 or MIPSxx class cores since 3572a2c37f
[MIPS: make oprofile use cp0_perfcount_irq if it is set] an

ERROR: "cp0_compare_irq" [arch/mips/oprofile/oprofile.ko] undefined!

error will happen.  Fixed by exporting cp0_compare_irq.

Uwe Kleine-König 4a043d79dc mips: mark const init data with __initconst instead of __initdata
As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with

	error: $variablename causes a section type conflict

because a section containing const variables is marked read only and so
cannot contain non-const variables.

Chris Metcalf d1cc1732cc arch/tile: provide kernel support for the tilegx USB shim
This change adds support for accessing the USB shim from within the
kernel.  Note that this change by itself does not allow the kernel
to act as a host or as a device; it merely exposes the built-in on-chip
hardware to the kernel.

The <arch/usb_host.h> and <arch/usb_host_def.h> headers are empty at
the moment because the kernel does not require any types or definitions
specific to the tilegx USB shim; the generic USB core code is all we need.
The headers are left in as stubs so that we don't need to modify the
hypervisor header (drv_usb_host_intf.h) from upstream.

Chris Metcalf 41bb38fc53 tile pci: enable IOMMU to support DMA for legacy devices
This change uses the TRIO IOMMU to map the PCI DMA space and physical
memory at different addresses.  We also now use the dma_mapping_ops
to provide support for non-PCI DMA, PCIe DMA (64-bit) and legacy PCI
DMA (32-bit).  We use the kernel's software I/O TLB framework
(i.e. bounce buffers) for the legacy 32-bit PCI device support since
there are a limited number of TLB entries in the IOMMU and it is
non-trivial to handle indexing, searching, matching, etc.  For 32-bit
devices the performance impact of bounce buffers should not be a concern.

pages that are cached in other ways (locally on a particular core,
uncached, user-managed incoherent, etc.).

A large part of the change is supporting flushing pages from cache
on particular homes so that we can transition the data that we are
delivering to or from the device appropriately.  The new homecache_finv*
routines handle this.

Some changes to page_table_range_init() were also required to make
the fixmap code work correctly on tilegx; it hadn't been used there
before.

We also remove some stub mark_caches_evicted_*() routines that
were just no-ops anyway.

Paul Bolle 3e219b9153 tile: remove unused header
Nothing includes memprof.h. Nothing uses the macros it defines. It seems
it is just a remnant of the proposed memprof functionality, which got
dropped before the Tilera architecture got added to the tree. This
header can safely be removed.

Linus Torvalds fe2e27bb92 ARM: SoC fixes for SPEAr
These are arriving very late in the release cycle, but there has been
 a change of maintainers on the SPEAr platform and they have needed a
 while to get going.
 
 The patch count is higher than I would like at this point, but they're
 all relevant fixes and well-contained in their own platform code. I still
 think it's suitable 3.5 material and I don't think it should increase
 the need for a -rc8 since they are so contained.

Heiko Carstens 0008204ffe s390/idle: fix sequence handling vs cpu hotplug
The s390 idle accounting code uses a sequence counter which gets used
when the per cpu idle statistics get updated and read.

One assumption on read access is that only when the sequence counter is
even and did not change while reading all values the result is valid.
On cpu hotplug however the per cpu data structure gets initialized via
a cpu hotplug notifier on CPU_ONLINE.
CPU_ONLINE however is too late, since the onlined cpu is already running
and might access the per cpu data. Worst case is that the data structure
gets initialized while an idle thread is updating its idle statistics.
This will result in an uneven sequence counter after an update.

As a result user space tools like top, which access /proc/stat in order
to get idle stats, will busy loop waiting for the sequence counter to
become even again, which will never happen until the queried cpu will
update its idle statistics again. And even then the sequence counter
will only have an even value for a couple of cpu cycles.

Fix this by moving the initialization of the per cpu idle statistics
to cpu_init(). I prefer that solution in favor of changing the
notifier to CPU_UP_PREPARE, which would be a different solution to
the problem.

KVM PV EOI optimization overrides eoi_write apic op with its own

For KVM use, we don't need any guarantees about when the switch to the
new op will take place, so it could in theory use this API after SMP init,
but it currently doesn't, and restricting callers to early init makes it
clear that it's safe as it won't race with actual APIC driver use.

use MCF_IRQ_PIT1 instead of MCFINT_VECBASE + MCFINT_PIT1 so we can support
those parts that have the pit1 interrupt on other than the first interrupt
controller.

Steven King eac5794994 m68knommu: refactor Coldfire GPIO not to require GPIOLIB, eliminate mcf_gpio_chips.
If we're not connecting external GPIO extenders via i2c or spi or whatever, we
probably don't need GPIOLIB.  If we provide an alternate implementation of
the GPIOLIB functions to use when only on-chip GPIO is needed, we can change
ARCH_REQUIRE_GPIOLIB to ARCH_WANTS_OPTIONAL_GPIOLIB so that GPIOLIB becomes
optional.

The downside is that in the GPIOLIB=n case, we lose all error checking done by
gpiolib, ie multiply allocating the gpio, free'ing gpio etc., so that the
only checking that can be done is if we reference a gpio on an external part.
Targets that need the extra error checking can still select GPIOLIB=y.

For the case where GPIOLIB=y, we can simplify the table of gpio chips to use a
single chip, eliminating the tables of chips in the 5xxx.c files.  The
original motivation for the definition of multiple chips was to match the way
many of the Coldfire variants defined their gpio as a spare array in memory.
However, all this really gains us is some error checking when we request a
gpio, gpiolib can check that it doesn't fall in one of the holes.  If thats
important, I think we can still come up with a better way of accomplishing
that.

Also in this patch is some general cleanup and reorganizing of the gpio header
files (I'm sure I must have had a reason why I sometimes used a prefix of
mcf_gpio and other times mcfgpio but for the life of me I can't think of it
now).

There is a few places that the m68k entry code uses the bsrl instruction

Greg Ungerer 5bd9dd4501 m68k: use some direct calls to ret_from_exception in entry code
The ret_from_excption code is referenced by its function name, or by a label
set at the start of its code. The non-MMU code can share some of this code
if we make direct calls to ret_from_exception instead of the associated label.
The effected function paths are: buserr, trap and ret_from_fork. So change
these to branch directly to ret_from_exception.

Will Drewry 5651721ede x86/vsyscall: allow seccomp filter in vsyscall=emulate
If a seccomp filter program is installed, older static binaries and
distributions with older libc implementations (glibc 2.13 and earlier)
that rely on vsyscall use will be terminated regardless of the filter
program policy when executing time, gettimeofday, or getcpu.  This is
only the case when vsyscall emulation is in use (vsyscall=emulate is the
default).

This patch emulates system call entry inside a vsyscall=emulate by
populating regs->ax and regs->orig_ax with the system call number prior
to calling into seccomp such that all seccomp-dependencies function
normally.  Additionally, system call return behavior is emulated in line
with other vsyscall entrypoints for the trace/trap cases.

Sylwester Nawrocki 353ba37a09 ARM: S3C24XX: Remove unused GPIO definitions for port J
There is no need now for individual GPIO port J pin control bit
definitions, the GPIO0..12 pins can be configured using the gpiolib
API. The GPJ* register address offset definitions for S3C2413 are
moved to the common mach-s3c24xx/include/mach/regs-gpio.h header.
These are still used outside of the gpio-samsung driver by PM code.

Switching GPJ port to camera function can be done for example with:
s3c_gpio_cfgall_range(S3C2410_GPJ(0), 13, S3C_GPIO_SFN(2), S3C_GPIO_PULL_NONE);

Make a common device tree glue for clocksource/dw_apb_timer.
Move mach-picoxcell/time.c to be a generic device tree application
of the dw_apb_timer.

Configure mach-picoxcell to use the dw_apb_timer_of device tree
implementation in drivers/clocksource.
