This patch puts the code from head.S in a special .bootstrap.text section. I'm working on a patch to reorder the functions in the kernel (I'll post that later), but for x86-64 at least the kernel bootstrap requires that the head.S functions are on the very first page/pages of the kernel text. This is understandable since the bootstrap is complex enough already and not a problem at all, it just means they aren't allowed to be reordered. This patch puts these special functions into a separate section to document this, and to guarantee this in the light of possibly reordering the rest later. (So this patch doesn't fix a bug per se, but makes things more robust by making the order of these functions explicit) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org> |
