7847777a45 atomic: cleanup asm-generic atomic*.h inclusion
After changing all consumers of atomics to include <linux/atomic.h>, we
ran into some compile time errors due to this dependency chain:

linux/atomic.h
  -> asm/atomic.h
    -> asm-generic/atomic-long.h

where atomic-long.h could use funcs defined later in linux/atomic.h
without a prototype.  This patches moves the code that includes
asm-generic/atomic*.h to linux/atomic.h.

Archs that need <asm-generic/atomic64.h> need to select
CONFIG_GENERIC_ATOMIC64 from now on (some of them used to include it
unconditionally).

Compile tested on i386 and x86_64 with allnoconfig.

148817ba09 asm-generic: add another generic ext2 atomic bitops
The majority of architectures implement ext2 atomic bitops as
test_and_{set,clear}_bit() without spinlock.

This adds this type of generic implementation in ext2-atomic-setbit.h and
use it wherever possible.

fbd60a7e87 efika: Fix board id detection
Current code is assuming that gpio_get_value() is returning 0 or 1 but it
should be checking if the value is 0 or not. Not doing it properly is breaking
the detection of the board (and thus the reboot of efika mx to2) when using
the new mxc gpio driver, which relies on basic mmio gpio.

aac927c93b OMAP: DSS2: rewrite use of context_loss_count
The function to get device's context loss count has changed from

omap_pm_get_last_off_on_transaction_id() to
omap_pm_get_dev_context_loss_count()

Change name of the function pointer in omapdss.h accordingly, and use
the term "context loss count" instead of "context id" in the code.

Restructure the context loss count functions to handle errors properly,
and ensure that context is always considered lost if an error happens.

/tmp/linux-3.0/arch/arm/include/asm/traps.h:12: warning: its scope is only this definition or declaration, which is probably not what you want

Nothing here depends on the layout of pt_regs or task_struct, so this
can be fixed by adding forward struct declarations to asm/traps.h.

d5341942d7 PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.
Aside of the usual motivation for constification,  this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.

Due to function pointer passing in varous places a few other functions
had to be constified as well.

6645cb61f3 ARM: Fix build errors caused by adding generic macros
Commit 66a625a (ARM: mm: proc-macros: Add generic proc/cache/tlb struct
definition macros) introduced build errors when PM_SLEEP is not enabled.
The per-CPU do_suspend/do_resume functions are defined via the
preprocessor to constant 0.  However, the macros which use these were
converted to assembly, resulting in undefined references to these
functions.  Fix that by moving the ! ifdef section into proc-macros.S
and deleting it from all effected proc-*.S files.

78359cb86b ARM: CPU hotplug: ensure we migrate all IRQs off a downed CPU
Our selection of interrupts to consider for IRQ migration is sub-
standard.  We were potentially including per-CPU interrupts in our
migration strategy, but omitting chained interrupts.  This caused
some interrupts to remain on a downed CPU.

We were also trying to migrate interrupts which were not migratable,
resulting in an OOPS.

Instead, iterate over all interrupts, skipping per-CPU interrupts
or interrupts whose affinity does not include the downed CPU, and
attempt to set the affinity for every one else if their chip
implements irq_set_affinity().

5dfc54e087 ARM: GIC: avoid routing interrupts to offline CPUs
The irq_set_affinity() method can be called with masks which include
offline CPUs.  This allows offline CPUs to have interrupts routed to
them by writing to /proc/irq/*/smp_affinity after hotplug has taken
a CPU offline.  Fix this by ensuring that we select a target CPU
present in both the required affinity and the online CPU mask.

Ensure that we return IRQ_SET_MASK_OK (which happens to be 0) on
success to ensure generic code copies the new mask into the irq_data
structure.

The original Cragganmore code was submitted while new code was being
refused for mainline. This patch was unexpectedly merged upstream but
development had continued in the expectation that the code would be
resubmitted later so no split patches were maintained. This patch
synchronises that work with the recently merged driver.

The main changes are fleshing out of the PMIC and audio integration for
the system, including addition of the Dallas Dhu and Tobermory audio
modules, plus some minor updates to account for revision 2 hardware.

f462904ef1 ARM: SAMSUNG: use regulator VDD for ADC
This patch allows the Samsung ADC driver to enable VDD regulator
at probe and resume and to disable at exit and suspend.
In a platform where ADC's VDD regulator is not "always-on", this
control is required although this patch does not provide fine-grained
power control (turning on the regulator only when being accessed).

However, if VDD regulator ("vdd" for the adc device) is not provided,
the regulator control will not be activated because there are platforms
that do not provide regulator for ADC device.

arch_initcall has been modified to module_init in order to allow
regulators to be available at probe.

decompressor to enter the kernel proper in the correct instruction
set state.

This patch changes the boot entry protocol for head.S and Image to
be the same as for zImage: in all cases, the kernel is now entered
in ARM.

Documentation/arm/Booting is updated to reflect this new policy.

A different rule will be needed for Cortex-M class CPUs as and when
support for those lands in mainline, since these CPUs don't support
the ARM instruction set at all: a note is added to the effect that
the kernel must be entered in Thumb on such systems.

4348810a24 ARM: btc: avoid invalidating the branch target cache on kernel TLB maintanence
Kernel space needs very little in the way of BTC maintanence as most
mappings which are created and destroyed are non-executable, and so
could never enter the instruction stream.

The case which does warrant BTC maintanence is when a module is loaded.
This creates a new executable mapping, but at that point the pages have
not been initialized with code and data, so at that point they contain
unpredictable information.  Invalidating the BTC at this stage serves
little useful purpose.

Before we execute module code, we call flush_icache_range(), which deals
with the BTC maintanence requirements.  This ensures that we have a BTC
maintanence operation before we execute code via the newly created
mapping.

So out it goes as well.

The PORT_S3C2400 definition in include/linux/serial_core.h is left there

align the naming scheme with device tree binding, which comes later.

It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

df4fa1f8dd ARM: kprobes: Add alu_write_pc()
This writes a new value to PC which was obtained as the result of an ARM
ALU instruction. For ARMv7 and later this performs interworking.

On ARM kernels we shouldn't encounter any ALU instructions trying to
switch to Thumb mode so support for this isn't strictly necessary.
However, the approach taken in all other instruction decoding is for us
to avoid unpredictable modification of the PC for security reasons. This
is usually achieved by rejecting insertion of probes on problematic
instruction, but for ALU instructions we can't do this as it depends on
the contents of the CPU registers at the time the probe is hit. So, as
we require some form of run-time checking to trap undesirable PC
modification, we may as well simulate the instructions correctly, i.e.
in the way they would behave in the absence of a probe.

3d4a99785a ARM: kprobes: Optimise emulation of LDM and STM
This patch improves the performance of LDM and STM instruction
emulation. This is desirable because.

- jprobes and kretprobes probe the first instruction in a function and,
  when the frame pointer is omitted, this instruction is often a STM
  used to push registers onto the stack.

- The STM and LDM instructions are common in the body and tail of
  functions.

- At the same time as being a common instruction form, they also have
  one of the slowest and most complicated simulation routines.

The approach taken to optimisation is to use emulation rather than
simulation, that is, a modified form of the instruction is run with
an appropriate register context.

Benchmarking on an OMAP3530 shows the optimised emulation is between 2
and 3 times faster than the simulation routines. On a Kirkwood based
device the relative performance was very significantly better than this.

235a4ce79f ARM: kprobes: Add common decoding function for LDM and STM
The encoding of these instructions is substantially the same for both
ARM and Thumb, so we can have common decoding and simulation functions.

This patch moves the simulation functions from kprobes-arm.c to
kprobes-common.c. It also adds a new simulation function
(simulate_ldm1_pc) for the case where we load into PC because this may
need to interwork.

The instruction decoding is done by a custom function
(kprobe_decode_ldmstm) rather than just relying on decoding table
entries because we will later be adding optimisation code.
