Subject: [09/38] sched: Fix up wchan borkage

3.0-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Simon Kirby <sim@...tway.ca>

commit 6ebbe7a07b3bc40b168d2afc569a6543c020d2e3 upstream.

Commit c259e01a1ec ("sched: Separate the scheduler entry for
preemption") contained a boo-boo wrecking wchan output. It forgot to
put the new schedule() function in the __sched section and thereby
doesn't get properly ignored for things like wchan.
