The byte order functions are visible to userspace. Unfortunately,
__arch_swab32() contains an assembly instruction which is invalid when
compiling for Thumb. This reverts to the C version when compiling for
Thumb.Signed-off-by: H. Peter Anvin

Patch from Andrew Victor
Some updates to the clock infrastructure for the AT91RM9200.
1. Hard-coded values replaced with names defined in at91rm9200_sys.h.
2. Added the four PIO clocks, which are enabled at startup.
3. At startup, disable all unused clocks.
4. Minor bugfix for usage counts associated with MCK. [Patch from David
Brownell]
5. Added at91_clock_associate() function to associate device & function
with a particular clock. [Patch from David Brownell]Signed-off-by: Andrew Victor

Patch from David Brownell
This adds the platform device for SSP/SPI controller, and declares
the ads7846 device hooked up to it. Not all Lubbock boards appear
to populate the connector needed to use this instead of the ucb1400
chip, but it can always be used as a temperature sensor.In short, this is probably most useful as an example of how to
provide the configuration data used by the pxa2xx_spi driver.
(Last tested against a slightly earlier version of that driver.)Signed-off-by: David Brownell

Patch from Ben Dooks
Using the low-level debug routines early in the
kernel debug cause the 1:1 mapping to get into
the TLB, which is not flushed until after the
CPU detection process (which needs the GPIO VA).This patch moves the VA for the GPIO to the
same offset as the physical offset of the UART
to the GPIO.Signed-off-by: Ben Dooks

Patch from Ben Dooks
If CONFIG_CPU_DCACHE_WRITETHOUGH is set, then the
S3C24XX PM code fails to compile, as there is no
need to flush the D-cache, the flush function
arm920_flush_kern_cache_all() is not compiled.Fix the code to not use this if the config is set.

Patch from Catalin Marinas
This code was still using the old format for the ARMv6 CPU id and it wasn't
flushing the caches on the MPCore CPU (and other ARM1176 cores). The patch
changes the mask bits to cope with the new id format.Signed-off-by: Catalin Marinas

Patch from Paul Brook
The old-abi sys_syscall syscall is broken when called from Thumb mode. It
assumes the syscall number is an Arm syscall number (ie. starts from
__NR_OABI_SYSCALL_BASE). In thumb mode syscall numbers start from zero.The patch below fixes this by clearing the nigh bits of the syscall number
instead of inverting them. Technically this means we accept some invalid
syscall numbers, but I can't see how that could be a problem. The two sets of
numbers far apart that unimplemented syscalls should still be rejected.Signed-off-by: Paul Brook

Being named "Crazed Snow-Weasel" instills a lot of confidence in this

Reflect the fact that the Cell Broadband Engine supports 64k
pages by adding the bit to the CPU features.Signed-off-by: Arnd Bergmann
Signed-off-by: Linus Torvalds -
The page size encoding passed to tlbie is incorrect for new-style
large pages. This fixes it. This doesn't affect anything on older
machines because mmu_psize_defs[psize].penc (the page size encoding)
is 0 for 4k and 16M pages (the two are distinguished by a separate "is
a large page" bit).Signed-off-by: Benjamin Herrenschmidt

arm_timer() checks PF_EXITING to prevent BUG_ON(->exit_state)
in run_posix_cpu_timers().However, for some reason it does so only for CPUCLOCK_PERTHREAD
case (which is imho wrong).Also, this check is not reliable, PF_EXITING could be set on
another cpu without any locks/barriers just after the check,
so it can't prevent from attaching the timer to the exiting
task.The previous patch makes this check unneeded.
Signed-off-by: Oleg Nesterov
Signed-off-by: Linus Torvalds -
do_exit() clears ->it_##clock##_expires, but nothing prevents
another cpu to attach the timer to exiting process after that.
arm_timer() tries to protect against this race, but the check
is racy.After exit_notify() does 'write_unlock_irq(&tasklist_lock)' and
before do_exit() calls 'schedule() local timer interrupt can find
tsk->exit_state != 0. If that state was EXIT_DEAD (or another cpu
does sys_wait4) interrupted task has ->signal == NULL.At this moment exiting task has no pending cpu timers, they were
cleanuped in __exit_signal()->posix_cpu_timers_exit{,_group}(),
so we can just return from irq.John Stultz recently confirmed this bug, see
