[PATCH] x86_64: Change default setting for noexec32 to match i386 kernel
This means i386 processes compiled with a recent compiler will get non executable heap by default now. This is the same default as a 32bit PAE kernel would use on a NX enabled CPU. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
