8792f7cf43 leds: add the sysfs interface into the leds-bd2802 driver for changing wave pattern and led current.
Allow the user application to change the wave pattern and led current by
'wave_pattern' and 'rgb_current' sysfs files.

b838901821 leds: fix led-bd2802 errors while resuming
LED_CORE_SUSPENDRESUME flag is not needed in the bd2802 driver, because
all works for suspend/resume is done in bd2802_suspend and bd2802_suspend
functions.  And this patch allows bd2802 to be configured again when it
resumes from suspend.

d26ed650d9 mm: don't rely on flags coincidence
Indeed FOLL_WRITE matches FAULT_FLAG_WRITE, matches GUP_FLAGS_WRITE,
and it's tempting to devise a set of Grand Unified Paging flags;
but not today.  So until then, let's rely upon the compiler to spot
the coincidence, "rather than have that subtle dependency and a
comment for it" - as you remarked in another context yesterday.

96f2ebd2e1 netxen: fix firmware init handshake
Make sure all functions run firmware init handshake.

If PCI function 0 fails to initialize firmware, mark the
state failed so that other functions on the same board
bail out quickly instead of waiting 30s for firmware
handshake.

bfdb4d9f0f timers: Fix timer_migration interface which accepts any number as input
Poornima Nayek reported:

| Timer migration interface /proc/sys/kernel/timer_migration in
| 2.6.30-git9 accepts any numerical value as input.
|
| Steps to reproduce:
| 1. echo -6666666 > /proc/sys/kernel/timer_migration
| 2. cat /proc/sys/kernel/timer_migration
| -6666666
|
| 1. echo 44444444444444444444444444444444444444444444444444444444444 > /proc/sys/kernel/timer_migration
| 2. cat /proc/sys/kernel/timer_migration
| -1357789412
|
| Expected behavior: Should 'echo: write error: Invalid argument' while
| setting any value other then 0 & 1

Restrict valid values to 0 and 1.

In the future it would be great if people could at least bother
figuring out how to use grep.

854c879f5a x86: Move init_gbpages() to setup_arch()
The init_gbpages() function is conditionally called from
init_memory_mapping() function. There are two call-sites where
this 'after_bootmem' condition can be true: setup_arch() and
mem_init() via pci_iommu_alloc().

Therefore, it's safe to move the call to init_gbpages() to
setup_arch() as it's always called before mem_init().

This removes an after_bootmem use - paving the way to remove
all uses of that state variable.

2eb2a43682 sh: SH7786 SMP support.
SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2
CPUs. This just wraps in to the existing SH-X3 SMP code with some minor
changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.

997d003093 sh: Use local TLB flush in set_pte_phys().
set_pte_phys() presently uses the global flush_tlb_one(), which locks on
SMP trying to do the IPI. As we have not even initialized the other CPUs
at this point, switch to the local_ variant so the flush happens on the
boot CPU.

9b901ee0cb [WATCHDOG] wdt_pci.c: remove #ifdef CONFIG_WDT_501_PCI
Change the wdt_pci.c watchdog driver so that the code is the same for
both the PCI-WDT500 as the PCI-WDT501 card. The selection of the card
is now being done via the module parameter: 'type' instead of the
config option CONFIG_WDT_501_PCI.

789cd4702b [WATCHDOG] OMAP fixes: enable clock in probe, trigger timer reload
This patch contains two fixes:

1)In omap_wdt_probe() the watchdog is reset and disabled. This
requires register access and the clks needs to be enabled temporarily

2)In omap_wdt_open() the timer register needs to be reloaded
to trigger a new timer value (the default of 60s)

Tested on OMAP34xx platform (Zoom1)

eebf8d86ac V4L/DVB (12131): BUGFIX: An incorrect Carrier Recovery Loop optimization table was being
loaded for a given chip version. This would cause the optimization in
tuning not to be applied and thus a failed expectation, in tuning speed
increment. The patch swaps the tables in use. It also fixes a possible
one in a million condition where state->dev_ver implies an older Cut
(Cut < 2.0, eventhough the driver doesn't attach to any Cut older than
2.0) or even negative (due to a bad I2C bus master driver) for the card
combination.

Thanks to Mauro Carvalho Chehab <mchehab@infradead.org> for pointing
out the issue at large.
