jkim c13c2b79cf Clean up RFLAG and CR3 register handling and nearby comments. For BSP, use
spinlock_enter()/spinlock_exit() to save/restore RFLAGS.  We know interrupt
is disabled when returning from S3.  For AP, we do not have to save/restore
it because IRET will do it for us any way.  Do not save CR3 locally because
savectx() does it and BSP does not have to switch to kernel map for amd64.
Change contigmalloc(9) flag while I am in the neighborhood.
