        src/sys/arch/x86/x86: pmap.c

Log Message:
Reorder these loops to reduce the number of enter->flush. I figured out
yesterday that this has a clear impact: a system with 16TB of hard-coded
ram has a 4-second black screen when booting. Now we're down to < 0.5s.

It could be optimized more, but verily I don't have a machine with P1GB
right now.
