If an error occurs after a successful 'of_icc_get()' call, it must be
undone.
Use 'devm_of_icc_get()' instead of 'of_icc_get()' to avoid the leak.
Update the remove function accordingly and axe the now unneeded
'icc_put()' calls.

When enabling per-CPU posix timers, an IPI to nohz_full CPUs might be
performed (to re-read the dependencies and possibly not re-enter
nohz_full on a given CPU).
A common case is for applications that run on nohz_full= CPUs
to not use POSIX timers (eg DPDK). This patch changes the notification

When adding a tick dependency to a task, its necessary to
wakeup the CPU where the task resides to reevaluate tick
dependencies on that CPU.
However the current code wakes up all nohz_full CPUs, which
is unnecessary.
Switch to waking up a single CPU, by using ordering of writes
to task->cpu and

Rather than waking up all nohz_full CPUs on the system, only wakeup

If the task is not running, run_posix_cpu_timers has nothing

Now that we're not racing with GPU setup, also fix races of timestamps
against other timestamps. In freedreno CI, we were seeing this path trigger
timeouts on setting the GMU bit, producing:
[drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0
and this triggered especiall
We were using the same force-poweron bit in the two codepaths, so they
could race to have one of them lose GPU power early.
freedreno CI was seeing intermittent errors like:
[drm:_a6xx_gmu_set_oob] *ERROR* Timeout waiting for GMU OOB set GPU_SET: 0x0
and this issue could have contributed to it.
