[PATCH] s/preempt_count()/in_atomic() in do_exit()

Linus,

This patch converts the debugging check in do_exit from a check on
preempt_count() to in_atomic().

The main benefit to this is we will stop warning over the BKL and now
use the standard mechanism for such checks.

Patch is against current BK, please apply.

	Robert Love
