96 mmap of /dev/mem
111 mmap of /sys/class/pci_bus/.../legacy_mem
114 	This is very similar to mmap of /dev/mem, except that legacy_mem
115 	only allows mmap of the one megabyte "legacy MMIO" area for a
124 	The /dev/mem mmap constraints apply.
126 mmap of /proc/bus/pci/.../??.?
129 	This is an MMIO mmap of PCI functions, which additionally may or
175 mmap of various MMIO regions from /dev/mem by "X" on Intel platforms
181       when the EFI memory map is incomplete, every /dev/mem mmap must
185 mmap of 0x0-0x9FFFF /dev/mem by "hwinfo" on HP sx1000 with VGA enabled
196       This mmap is done with user pages, not kernel identity mappings,
205 mmap of 0x0-0xFFFFF legacy_mem by "X"
209       same attributes, we can allow the mmap (and we will prefer WB if
214       machines with VGA enabled), we must fail the mmap because there's no
219       mmap and force the user to map just the specific region of interest.
221 mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled
228       This is a special case of the previous case, and the mmap should
