[PATCH] fix kexec asm
While testing kexec and kdump we hit problems where the new kernel would freeze or instantly reboot. The easiest way to trigger it was to kexec a kernel compiled for CONFIG_M586 on an athlon cpu. Compiling for CONFIG_MK7 instead would work fine. The patch fixes a few problems with the kexec inline asm. Signed-off-by: Chris Mason <mason@suse.com> Acked-by: "Eric W.
