This sits on top of my last two patches to sysfs (the one that adds mmap
support and the one that exports PCI resources in sysfs). It adds per-bus
legacy_io and legacy_mem files for use by userspace applications that want to
do legacy port I/O or access legacy ISA memory. It's protected by a new
HAVE_PCI_LEGACY ifdef modeled after HAVE_PCI_MMAP since not all arches will
support it. It's really just an RFC at this point, I have to rediff once
Greg incorporates the above patches (the second of which I have to rediff and
resubmit).
Thanks,
Jesse
