sys/arch/amd64/amd64: bus_space.c
Log message:
Change amd64 bus_space_{map,unmap} to be the same as i386. While
theoretically the current solution of using the direct (and direct
uncached) maps is better for tlb pressure, two direct maps is dangerous,
especially when we support Page Attribute Tables (soon), since that will
cause illegal cache aliases. When that work is done a clever solution
may be worked out.
