[PATCH] x86_64: Make kernel math errors a die() now
There were no reports about the previous warning for FPU exceptions in the kernel, so make it a die() now. Also improve the error messages slightly. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
