-Subject: [PATCH] efi: prune invalid memory map entries
-
-Some machines, such as the Lenovo ThinkPad W541 with firmware GNET80WW
-(2.28), include memory map entries with phys_addr=0x0 and num_pages=0.
-
-Currently the log output for this case (with efi=debug) looks like:
-
-[    0.000000] efi: mem45: [Reserved           |   |  |  |  |  |  |  |  |  |  |  |  ] range=[0x0000000000000000-0xffffffffffffffff] (0MB)
-
-This is clearly wrong, and also not as informative as it could be.  This
-patch changes it so that if we find obviously invalid memory map
-entries, we print an error and those entries.  It also detects the
-display of the address range calculation overflow, so the new output is:
-
-[    0.000000] efi: [Firmware Bug]: Invalid EFI memory map entries:
-[    0.000000] efi: mem45: [Reserved           |   |  |  |  |  |  |  |   |  |  |  |  ] range=[0x0000000000000000-0x0000000000000000] (invalid)
-
-It also detects memory map sizes that would overflow the physical
-address, for example phys_addr=0xfffffffffffff000 and
-num_pages=0x0200000000000001, and prints:
-
-[    0.000000] efi: [Firmware Bug]: Invalid EFI memory map entries:
-[    0.000000] efi: mem45: [Reserved           |   |  |  |  |  |  |  |   |  |  |  |  ] range=[phys_addr=0xfffffffffffff000-0x20ffffffffffffffff] (invalid)
-
-It then removes these entries from the memory map.
