omap: remove BUG_ON for disabled interrupts

Remove a BUG_ON for when interrupts are disabled during an MMC request.

During boot, interrupts can be disabled when a request is made, causing
this bug to be triggered.  In reality, there's no reason this should halt
the kernel, as the driver has proved reliable in spite of disabled
interrupts, and additionally, there's nothing in this code that would
require interrupts to be enabled.

The only setup I've managed to make it trigger on is on the HTC Herald
during bootup when the driver is built into the kernel (mostly because
that's all I have).  I believe it's related to the fact that on bootup I
get many timeout errors on "CMD5" while initializing the card.  Each CMD5
timeout triggers that bug (I changed it to a WARN_ON to get it to boot in)
due to the fact that part of the timeout code involves sending the request
again.  With interrupts turned off, that BUG would be triggered.

And Johannes's patch 0aeb2339e54e ("vmscan: remove all_unreclaimable scan

Child groups should have a greater depth than their parents.  Prior to
this change, the parent would incorrectly report zero memory usage for
child cgroups when use_hierarchy is enabled.

test script:
  mount -t cgroup none /cgroups -o memory

sys_personality: change sys_personality() to accept "unsigned int" instead of u_long

task_struct->pesonality is "unsigned int", but sys_personality() paths use
"unsigned long pesonality".  This means that every assignment or
comparison is not right.  In particular, if this argument does not fit
into "unsigned int" __set_personality() changes the caller's personality
and then sys_personality() returns -EINVAL.

Turn this argument into "unsigned int" and avoid overflows.  Obviously,
this is the user-visible change, we just ignore the upper bits.  But this
can't break the sane application.

There is another thing which can confuse the poorly written applications.
User-space thinks that this syscall returns int, not long.  This means
that the returned value can be negative and look like the error code.  But
note that libc won't be confused and thus errno won't be set, and with
this patch the user-space can never get -1 unless sys_personality() really
fails.  And, most importantly, the negative RET != -1 is only possible if
that app previously called personality(RET).

ACPI: Fix the incorrect calculation about C-state idle time

The C-state idle time is not calculated correctly, which will return the wrong
residency time in C-state. It will have the following effects:
   1.  The system can't choose the deeper C-state when it is idle next time.
Of course the system power is increased. E.g. On one server machine about 40W
idle power is increased.
   2.  The powertop shows that it will stay in C0 running state about 95% time
although the system is idle at most time.

perf: Fix crash in swevents

Frederic reported that because swevents handling doesn't disable IRQs
anymore, we can get a recursion of perf_adjust_period(), once from
overflow handling and once from the tick.

If both call ->disable, we get a double hlist_del_rcu() and trigger
a LIST_POISON2 dereference.

Since we don't actually need to stop/start a swevent to re-programm
the hardware (lack of hardware to program), simply nop out these
callbacks for the swevent pmu.
