PATCH 1/1 2.4-ac: more yield abstractions

Alan,

The attached patch should replace the remaining occurrences of

	current->policy |= SCHED_YIELD;
	schedule();

with

	yield();

I missed this previously because they are in arch-dependent non-x86 code. Patch is against 2.4.19-pre7-ac4, please apply.

Robert Love
