[PATCH] sched: Resolve some shadow warnings

[PATCH] sched: Resolve some shadow warnings

[Jeff Kirsher]

From: Mark Rustad <mark.d.rustad@intel.com>

Using names like down and up, which are well-known semaphore
functions, makes those functions unavailable. This can be a
trap for the future, should there be reason to call down or
up here. Mostly it is just noise, so make it go away by using
other names.
