CONFIG_UBSAN && !CONFIG_CPU_IDLE, this optimisation no longer happens
and the kernel fails to link since cpuidle_devices is not defined.

This patch introduces an accessor function for the current CPU cpuidle

drm/exynos/decon5433: handle vblank in vblank interrupt

vblank should be signaled to userspace as soon as possible after sending
frame. INTFRMDONEPEND irq looks to be the best moment.
Handling it in TE interrupt looks wrong - TE triggers reading framebuffers
so it is the worst moment, it could result in delayed frame update.
Other benefit of moving vblank handiling to vblank interrupt is possibility
to eliminate TE irq handler in case of HWTRIGGER.

ARM: mali400: r5p2_rel0: add GLES mem profiler feature

This patch adds GLES mem profiler feature.

You could use it by "cat /sys/kernel/debug/mali/gles_mem/<PID>".
Without user-DDK's MALI_IOC_MEM_PROFILE_GLES_MEM, it only show layout.

With this ioctl, you could check current GLES relevant memory status
in opened session and also check memory leakage in trash subdirectory.

The mechanism of detecting memory leakage is checking information when
the session is closed. So the user misses to free (GLES)memory during
session, it(the PID) could be found in trash.

Caution! When app is killed and the session is forcely shut down, then
it(the PID) could be found in trash but we can not guarantee there is a
real memory leakage. That is because like this case, it is impossible
to call MALI_IOC_MEM_PROFILE_GLES_MEM to remove allocated memory.
