This patch pushes the creation of a rare signal frame (SIGBUS or SIGSEGV) into a separate function, thus saving stackspace in the main do_page_fault() stackframe. The effect is 132 bytes less of stack used by the typical do_page_fault() invocation - resulting in a denser cache-layout. (Another minor effect is that in case of kernel crashes that come from a pagefault, we add less space to the already existing frame, giving the crash functions a slightly higher chance to do their stuff without overflowing the stack.) (The changes also result in slightly cleaner code.) argument bugfix from "Guillaume C." <guichaz@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> |
