[PATCH] arch/i386/kernel/microcode.c: remove the obsolete microcode_ioctl
Nowadays, even Debian stable ships a microcode_ctl utility recent enough to no longer use this ioctl. Signed-off-by: Adrian Bunk <bunk@stusta.de> Acked-by: Tigran Aivazian <tigran_aivazian@symantec.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
