Modified Files:
	src/sys/arch/amd64/amd64: locore.S

Log Message:
cpu_switchto: PCB_CR0(%r14) is a 32bit value, so don't use movq to retrieve it.
Using movq would copy pcb_flags along as well, which would cause traps
because bad bits would be written into %cr0 a few instructions later.
This wouldn't happen for native NetBSD processes (no pcb_flags set), but
it would happen for Linux processes.
