87     mmap of /dev/mem
101     mmap of /sys/class/pci_bus/.../legacy_mem
103 	This is very similar to mmap of /dev/mem, except that legacy_mem
104 	only allows mmap of the one megabyte "legacy MMIO" area for a
113 	The /dev/mem mmap constraints apply.
115     mmap of /proc/bus/pci/.../??.?
117     	This is an MMIO mmap of PCI functions, which additionally may or
160     mmap of various MMIO regions from /dev/mem by "X" on Intel platforms
165       when the EFI memory map is incomplete, every /dev/mem mmap must
169     mmap of 0x0-0x9FFFF /dev/mem by "hwinfo" on HP sx1000 with VGA enabled
176       This mmap is done with user pages, not kernel identity mappings,
185     mmap of 0x0-0xFFFFF legacy_mem by "X"
188       same attributes, we can allow the mmap (and we will prefer WB if
193       machines with VGA enabled), we must fail the mmap because there's no
198       mmap and force the user to map just the specific region of interest.
200     mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled
205       This is a special case of the previous case, and the mmap should
