spec->cur_adc isn't set until cs_capture_pcm_prepare() is called although
the driver tries to select the connection at init time and at auto-mic
switch. This results in the access to the widget NID 0, which is
obviously invalid, also a wrong capture source.
This patch fixes the issue by issuing the connect-select verb conditionally
at appropriate places.

The Intel HDMI chips (ironlake at least) are found to have ~250ms delay
between the ELD_Valid=1 hotplug event is send and the ELD buffer becomes
actually readable. During the time the ELD buffer is mysteriously all 0.
Fix it by scheduling a delayed work to re-read ELD buffer after 300ms.

memset(eld) clears eld->proc_entry which will leak the struct
snd_info_entry when unloading module.
Fix it by
- memset only the fields before eld->eld_buffer
- set eld->eld_valid to true _after_ all eld fields have been filled

Clean up and fix pwr_nids for 92HD71 / 73 / 83 family codecs; remove
pwr_mapping which was incorrect.
The original pwr_nids support of 92HD83xxx was incorrect and never
actually worked before. Now we should have things working correctly
without having to hack by DID anymore.
It is also not necessary to explicitly turn on all the pins near the
beginning of patch_stac92hd83xxx() now, the pins will go though
initialization properly.
Tested on 92HD66 / 71 / 73 / 75 / 83 / 89 / 91 demo boards.

genirq: Fix irqfixup, irqpoll regression

commit d05c65fff0 ("genirq: spurious: Run only one poller at a time")
introduced a regression, leaving the boot options 'irqfixup' and
'irqpoll' non-functional. The patch placed tests in each function, to
exit if the function is already running. The test in 'misrouted_irq'
exited when it should have proceeded, effectively disabling
'misrouted_irq' and 'poll_spurious_irqs'.
The check for an already running poller needs to be "!= 1" not "== 1"
as "1" is the value when the first poller starts running.

If there is an architecture-specific random number generator we use it
to acquire randomness one "long" at a time. We should put these random
words into consecutive words in the result buffer - not just overwrite

'readelf -n' on the s390 vmlinux file generates lots of warnings about
corrupt notes. The reason is that the 'NOTE' program header has incorrect
file and memory sizes. The problem is that the section following the
NOTES section do not switch to a different phdr and they get added to
the NOTE program section. Add a dummy entry to the linker script that
switches to the data phdr before the start of the RODATA section.

I am running SMP Linux 2.6.37-rc1 on BMIPS5000 (single core dual thread)
and observe some abnormalities when doing system suspend/resume which I
narrowed down to cpu hotplugging. The suspend brings the second thread
processor down and then restarts it, after which I see memory corruption
in userspace. I started digging and found out that problem occurs because
while doing execve() the child process is getting the same ASID as the
parent, which obviously corrupts parent's address space.
Further digging showed that activate_mm() calls get_new_mmu_context() to
get a new ASID, but at this time ASID field in entryHi is 1, and
asid_cache(cpu) is 0x100 (it was just reset to ASID_FIRST_VERSION when
the secondary TP was booting).
So, get_new_mmu_context() increments the asid_cache(cpu) value to
0x101, and thus puts 0x01 into entryHi. The result - ASID field does
not get changed as it was supposed to.
My solution is very simple - do not reset asid_cache(cpu) on TP warm
restart.

The Kernel hangs occasionally during boot after "Calibrating delay loop..".
This is caused by the c0_compare_int_usable() routine in cevt-r4k.c
returning false which causes the system to disable the timer and hang later.
The false return happens because the routine is using a series of four calls
to irq_disable_hazard() as a delay while it waits for the timer changes to
propagate to the cp0 cause register. On newer MIPS cores, like the 74K, the
series of irq_disable_hazard() calls turn into ehb instructions and can take
as little as a few clock ticks for all 4 instructions. This is not enough of
a delay, so the routine thinks the timer is not working. This fix uses up
to a max number of cycle counter ticks for the delay and uses
back_to_back_c0_hazard() instead of irq_disable_hazard() to handle the
hazard condition between cp0 writes and cp0 reads.

This is to exclude it from force threading to allow RT patch set to work.
And while on this line
* Remove IRQF_DISABLED as as this flag is NOOP
* Add IRQF_PERCPU as this is a per cpu interrupt.

Since eb9ae7f2 (gpio: fix build error in include/asm-generic/gpio.h)
the generic version of gpio.h calls __gpio_{set,get}_value which we
do not define. Get rid of asm-generic/gpio.h and define the missing
stubs directly for BCM47xx to build.

Cause is a misplaced bracket.
The code
strlen(buf+1)
will be two bytes less than
strlen(buf)+1
The +1 is in this code to reserve space for an additional space character.

I assumed all PCI buses had a bridge, but playing with qemu recently, I
discovered vgaarb bug where it wasn't detecting both devices shared a bridge
at the root level.
Don't check for NULL, if two buses have a NULL bridge, assume they share the
root bus.

commit 27641c3f (drm/vblank: Add support for precise vblank
timestamping) adds preempt_disable()/enable() around a spin locked
section with the comments:
* Disable preemption, so vblank_time_lock is held as short as
* possible, even under a kernel with PREEMPT_RT patches.
/* Disable preemption while holding vblank_time_lock. Do
* it explicitely to guard against PREEMPT_RT kernel.
Just that this has never been tested on a RT kernel which would have
granted that nonsense with a might_sleep() warning because
dev->vblank_time_lock is converted to a "sleeping" spinlock on RT.
So this is activly wrong on RT and superflous on mainline. Remove it.

The current implementation of dmi_name_in_vendors() is an invitation to
lazy coding and false positives [1]. Searching for a string in 8 know
what you're looking for, so you should know where to look. strstr isn't
fast, especially when it fails, so we should avoid calling it when it
just can't succeed.
Looking at the current users of the function, it seems clear to me that
they are looking for a system or board vendor name, so let's limit
dmi_name_in_vendors to these two DMI fields. This much better matches
the function name, BTW.
[1] We currently have code looking for short names in DMI data, such as
"IBM", "ASUS" or "Acer". I let you guess what will happen the day other
vendors ship products named, for example, "SCHREIBMEISTER", "PEGASUS" or
"Acerola".

Commit c9f01245 ("oom: remove oom_disable_count") has removed the
oom_disable_count counter which has been used for early break out from
oom_badness so we could never select a task with oom_score_adj set to
OOM_SCORE_ADJ_MIN (oom disabled).
Now that the counter is gone we are always going through heuristics
calculation and we always return a non zero positive value. This means
that we can end up killing a task with OOM disabled because it is
indistinguishable from regular tasks with 1% resp. CAP_SYS_ADMIN tasks
with 3% usage of memory or tasks with oom_score_adj set but OOM enabled.
Let's break out early if the task should have OOM disabled.

The driver for the DigsyMTC display configuration EEPROMs device got
added by commit 469dded183 ("misc/eeprom: add eeprom access driver for
digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But
at the time that driver got added PPC_MPC5200_GPIO was already renamed
to GPIO_MPC5200, by commit 6eae1ace68 ("gpio: Move mpc5200 gpio driver
to drivers/gpio").
So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200
itself implies that GPIOLIB is set, that dependency can be dropped.
