Date: Mon, 19 Oct 2009 10:25:43 -0400 (EDT) From: "Ryan C. Gordon" <icculus@...ulus.org> To: linux-kernel@...r.kernel.org Subject: [PATCH] binfmt_elf: Reorder objects in Makefile to favor platform default. Reordered object list so compat_binfmt_elf.o comes first. This will make it call register_binfmt() first, inserting it at the end of the list. Now the kernel will try the compatibility formats as a backup if the actual system format rejects the binary. As almost all binaries loaded won't be compatibility formats, this saves a few cycles for each process. Signed-off-by: Ryan C.
