I tried to kexec on my x64 and it hangs up in calibrate_delay() because
the PIT never fires any interrupts so jiffies is never updated. Has
kexec been tested on x64 and should be working? I want to know if I
should start looking at weirdness with my hardware or if it is like this
on all x64 boxes.

Also, patch at bottom is needed to compile kexec on x64 without ia32
emulation support (the includes are not used at the moment).
