Fairly minor cleanups to wli's recent __sched implementation:

Name: Minor __sched Cleanups
Status: Tested on 2.6.5-mm4
Version: -mm

1) __sched_text_start and __sched_test_end are more normal section
marker names, and can be used directly.

2) There is no comment and no reason for __sched to be in linux/init.h:
linux/sched.h would be preferable.
