From 379b5441aeb895fe55b877a8a9c187e8728f774c Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Fri, 27 Jan 2006 14:02:47 -0800 Subject: x86: align per-cpu section to configured cache bytes This matches the fix for a bug seen on x86-64. Test booted on old hardware that had 32 byte cachelines to begin with.

Once this behavior is fixed, all files in the kernel rebuild every time, even if nothing has changed. This patch ensures kbuild works with both the incorrect and correct behaviors of GNU make. For more details on the incorrect behavior, see: http://lists.gnu.org/archive/html/bug-make/2006-03/msg00003.html Changes in this patch: - Keep all targets that are to be marked .PHONY in a variable, PHONY. - Add .PHONY: $(PHONY) to mark them properly. - Remove any $(PHONY) files from the $? list when determining whether targets are up-to-date or not.
