HID: fix a crash in hid_report_raw_event() function.

I'm using a Data Modul EasyTouch USB multitouch controller,
which is issuing a hid report with a size equals to 0. The rsize
value gets set to 536870912 and Linux is crashing in the memset
because the value is too big.

sched: Introduce SCHED_POWER_SCALE to scale cpu_power calculations

SCHED_LOAD_SCALE is used to increase nice resolution and to
scale cpu_power calculations in the scheduler. This patch
introduces SCHED_POWER_SCALE and converts all uses of
SCHED_LOAD_SCALE for scaling cpu_power to use SCHED_POWER_SCALE
instead.

This is a preparatory patch for increasing the resolution of
SCHED_LOAD_SCALE, and there is no need to increase resolution
for cpu_power calculations.

ipc: Add missing sys_ni entries for ipc/compat.c functions

When building with:

  CONFIG_64BIT=y
  CONFIG_MIPS32_COMPAT=y
  CONFIG_COMPAT=y
  CONFIG_MIPS32_O32=y
  CONFIG_MIPS32_N32=y
  CONFIG_SYSVIPC is not set
  (and implicitly: CONFIG_SYSVIPC_COMPAT is not set)

the final link fails with unresolved symbols for:

  compat_sys_semctl, compat_sys_msgsnd, compat_sys_msgrcv,
  compat_sys_shmctl, compat_sys_msgctl, compat_sys_semtimedop

The fix is to add cond_syscall declarations for all syscalls in
ipc/compat.c

spinlock_up.h: include asm/processor.h in for cpu_relax

Commit e66eed651fd1 ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h and this was a
path to including asm/processor.h.  We need to include it excplicitly
now.

Fixes this build error on sparc32 (at least):

ktest: Allow options to be used by other options

There are cases where one ktest option may be used within another
ktest option. Allow them to be reused just like config variables
but there are evaluated at time of test not config processing time.

Thus having something like:

MAKE_CMD = make ARCH=${ARCH}

TEST_START
ARCH = powerpc

TEST_START
ARCH = arm

Will have the arch defined for each test iteration.

ARM: 6902/1: perf: Remove erroneous check on active_events

When initialising a PMU, there is a check to protect against races with
other CPUs filling all of the available event slots. Since armpmu_add
checks that an event can be scheduled, we do not need to do this at
initialisation time. Furthermore the current code is broken because it
assumes that atomic_inc_not_zero will unconditionally increment
active_counts and then tries to decrement it again on failure.

This patch removes the broken, redundant code.
