Subject[PATCH] sched: Hide runqueues from direct refer at source code level for __raw_get_cpu_var()
From

description:

My previous patch (Commit-ID of tip tree d11ad9b3631b942b0d2e5b754a6c62158efb799f) hides
direct refers at source code level into macros.
This will hide the rest part, __raw_get_cpu_var().
After appling this, all of the direct refer to runqueues will be in macros in the close place.
