Thomas Gleixner 8933a52534 sched: Reenable interrupts in do_sched_yield() ...

[ Upstream commit 345a957fcc ]

do_sched_yield() invokes schedule() with interrupts disabled which is
not allowed. This goes back to the pre git era to commit a6efb709806c
("[PATCH] irqlock patch 2.5.27-H6") in the history tree.

Reenable interrupts and remove the misleading comment which "explains" it.
