perf: Treat attr.config as u64 in perf_swevent_init()

Trinity discovered that we fail to check all 64 bits of
attr.config passed by user space, resulting to out-of-bounds
access of the perf_swevent_enabled array in
sw_perf_event_destroy().

Introduced in commit b0a873e ("perf: Register PMU
implementations").

Make sure PWMs are running in sync.

The 3 (red, green, blue) PWMs were sometimes running out of sync,
depending on the notification LED color flow and timing.

Make sure they are running in sync by
- adjusting the PWM atomically (that is, not adjust each one within its
  own worker task, where other tasks could get run inbetween)
- restarting the PWM if it was running before

Mako: Revert msm_fb: remove background invert alpha option for alpha drop pipe

This fixes the pie controls visual glitch when launching apps on the mako and
is required for this http://review.cyanogenmod.org/#/c/35314/ to work.

  When the blended background pipe has dropped alpha and it is going to
  be blended with foreground pipe on the next stage,
  MDP4_BLEND_BG_ALPHA_FG_CONST is taken. Foreground alpha constant is
  0xFF, so we need to use this alpha value to show background, instead
  of its inverted value.
