[LV-k25-commit] CVS: kernel-2.5/arch/vax/kernel process.c,1.7,1.8

[Kenn H. <ke...@us...>]

Update of /cvsroot/linux-vax/kernel-2.5/arch/vax/kernel
In directory sc8-pr-cvs1:/tmp/cvs-serv7720

Modified Files:
	process.c 
Log Message:
switch_to no longer needs to return the last task.  Also drop call to
check_pgt_cache from idle loop, since 2.5.5 no longer maintains page
table lookaside lists.
