From 40bdac7dbc161639a498697f34fbd1ee800e51f4 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 8 Feb 2009 22:00:55 -0800 Subject: sparc64: Kill .fixup section bloat. This is an implementation of a suggestion made by Chris Torek: -------------------- Something else I noticed in passing: the EX and EX_LD/EX_ST macros scattered throughout the various .S files make a fair bit of .fixup code, all of which does the same thing. At the cost of one symbol in copy_in_user.S, you could just have one common two-instruction retl-and-mov-1 fixup that they all share. -------------------- The following is with a defconfig build: text data bss dec hex filename 3972767 344024 584449 4901240 4ac978 vmlinux.orig 3968887 344024 584449 4897360 4aba50 vmlinux Signed-off-by: David S.
