[PATCH] m32r: security fix of {get,put}_user macros
Update {get,put}_user macros for m32r kernel. - Modify get_user to use __get_user_asm macro, instead of __get_user_x macro. - Remove arch/m32r/lib/{get,put}user.S. - Some cosmetic updates. I would like to thank NIIBE Yutaka for his reporting about the m32r kernel's security problem in {get,put}_user macros. There were no address checking for user space access in {get,put}_user macros. ;-) Signed-off-by: Hirokazu Takata <takata@linux-m32r.org> Cc: NIIBE Yutaka <gniibe@fsij.org> Cc: <stable@kernel.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
