[PATCH] Fix mmap() of /dev/hpet
The address passed to io_remap_pfn_range() in hpet_mmap() does not need to
be converted using __pa(): it is already a physical address. This bug was
found and the patch suggested by Clay Harris.
I introduced this particular bug when making io_remap_pfn_range changes a
few months ago. In fact mmap()ing /dev/hpet has *never* previously worked:
before my changes __pa() was being executed on an ioremap()ed virtual
address, which is also invalid.
