Modified files:
sys/arch/amd64/include: bus.h
sys/arch/i386/include: bus.h
Log message:
the bus_space api implies that there's a bus endianness that it will
swap for you to the hosts endianness. sometimes you dont want this hand
holding and just want raw access to the registers. bus_space does have
stuff to do this already, but they deal with buffers which can be awkward
if you just want to get or set a single register.
this adds the following to i386 and amd64:
bus_space_read_raw_2() bus_space_read_raw_4() bus_space_read_raw_8()
bus_space_write_raw_2() bus_space_write_raw_4() bus_space_write_raw_8()
sparc64 already implements this, even though it wasnt part of the
official api. how handy.
i'll do other archs as i can.
kettenis@ and miod@ seem ok with this
