[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.
