Everything is there for a reason, including setting the guarded flag if
the PTE indicates this should be done.  Since it doesn't seem to be clear
from messages I've sent in the past, the guarded flag is used to ensure
the proper order of operation on I/O spaces.  Any ioremap will request
this feature.

Thanks.
