[HYBRID] : mapping IO mems in the EPT
Hi guys,
During my refresh to latest linux, I noticed, direct mapping of all
non-RAM pages in xen_set_identity_and_release(). I currently don''t map
all at front, but as needed looking at the PAGE_IO bit in the pte. One
result of that is minor change to common code macro:
__set_fixmap(idx, phys, PAGE_KERNEL_NOCACHE) to
to __set_fixmap(idx, phys, PAGE_KERNEL_IO_NOCACHE)
