[PATCH] paravirt: remove set pte atomic
Now that ptep_establish has a definition in PAE i386 3-level paging code, the only paging model which is insane enough to have multi-word hardware PTEs which are not efficient to set atomically, we can remove the ghost of set_pte_atomic from other architectures which falesly duplicated it, and remove all knowledge of it from the generic pgtable code. set_pte_atomic is now a private pte operator which is specific to i386 Signed-off-by: Zachary Amsden <zach@vmware.com> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Jeremy Fitzhardinge <jeremy@xensource.com> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
