When CONFIG_UIDGID_STRICT_TYPE_CHECKS is enabled, plain integer checking
between different uids/gids is explicitely turned into a build failure
by making the k{uid,gid}_t types a structure containing a value:
arch/mips/kernel/mips-mt-fpaff.c: In function 'check_same_owner':
arch/mips/kernel/mips-mt-fpaff.c:53:22: error: invalid operands to
binary == (have 'kuid_t' and 'kuid_t')
arch/mips/kernel/mips-mt-fpaff.c:54:15: error: invalid operands to
binary == (have 'kuid_t' and 'kuid_t')
In order to ensure proper comparison between uids, using the helper
function uid_eq() which performs the right thing whenever this config
option is turned on or off.

The patch needs to eliminate the definition of OCTEON_IRQ_BOOTDMA so
that the device tree code can map the interrupt, so in order to not
temporarily break things, we do a single patch to both the interrupt
registration code and the pata_octeon_cf driver.
Also rolled in is a conversion to use hrtimers and corrections to the
timing calculations.

Manuel Lauss <manuel.lauss@gmail.com> writes:
I introduced it as a fallback because early revisions of Alchemy hardware
we shipped had a non-functional 32kHz timer and had to rely on the r4k
timer instead. Previously the r4k timer was initialized regardless, but
it's useless with the "wait" instruction.
So long story short: I need either the on-chip 32kHz timer OR the r4k
timer if the 32kHz one is unusable, but not both, and r4k timer is useless
when au1k_idle is in use.
The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm
not against removing R4K_LIB symbols.

With the upcoming merge of the ARC architecture there is a small likelyhood
of conflicting use for the CONFIG_ARC config symbol. Rename it to
CONFIG_FW_ARC. Also rename CONFIG_ARC32 to CONFIG_FW_ARC32, CONFIG_ARC64
to CONFIG_FW_ARC64.
For consistence also rename CONFIG_SNIPROM to CONFIG_FW_SNIPROM and
CONFIG_CFE to CONFIG_FW_CFE.

Intc_enable_or_unmask() is called at the last stage of handle_level_irq().
This function enables the irq first (Write INTC.SIE) and clear ISR next (Write INTC.IAR).
This would create problems that processor will get into a new interrupt as soon as SIE
is written because the previous level interrupt has been captured by INTC.
If the description bring some puzzles, here is the details of how interrupt is handled
for MicroBlaze after Interrupt signal is detected:
1. disable INTC (INTC.CIE = 1)
2. Acknowledge INTC (INTC.IAR = 1)
3. gets into interrupt source's handler, for example, timer's handler
4. Timer is interrupt handler acknowledge Timer Interrupt Status (Timer.TCSR0[23] = 1), and return
5. Enable INTC (INTC.SIE = 1)
6. Acknowledge INTC (INTC.IAR = 1)
INTC continue to capture source inputs even if INTC is disabled (INTC.IER == 1).
So between the gap of step 2 and step 3, the level interrupt from source makes INTC captures
a new interrupt and thus the INTC.ISR = 1 during step 3, 4, and 5.
When INTC is enabled in step 5, INTC's interrupt output will go high immediately.
In summary, the driver should issue step 6 before step 5.

__pu_val must be volatile to ensure that the value is not lost.
It was causing the problem with timerfd syscall
where using inline asm at the end of function call doesn't
save u64 bit value to the stack.
In comparison both cases you can find out this fragment
where you can see the first part which is saved u64
value to stack and then using it in __put_user_asm_8 macro.
Origin broken implementation misses the first two swi instructions.
swi r22, r1, 28 /* missing without volatile */
swi r23, r1, 32
...
addik r4, r1, 28
lwi r3, r4, 0
swi r3, r25, 0
lwi r3, r4, 4
swi r3, r25, 4
addk r3, r0, r0
NOTE: Moving __put_val initialization after declaration
has not impact on this bug. It is just coding style issue.

Support having the PCI bus be removed at runtime and rediscovered.
gregkh@linuxfoundation.org argued for removing __init rather
than converting it to __devinit.

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."

Pull ARM SoC updates from Olof Johansson:
"This contains the bulk of new SoC development for this merge window.
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."
Fix up trivial conflicts as per Olof.

Pull ARM SoC cleanups on various subarchitectures from Olof Johansson:
"Cleanup patches for various ARM platforms and some of their associated
drivers. There's also a branch in here that enables Freescale i.MX to
be part of the multiplatform support -- the first "big" SoC that is
moved over (more multiplatform work comes in a separate branch later
during the merge window)."
Conflicts fixed as per Olof, including a silent semantic one in
arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to
omap3xxx_restart(), and a new user of the old name was added).
