[PATCH 1/2] Remove EFI memmap quirk for UV

From: Alex Thorlton
Date: Mon Nov 16 2015 - 13:00:00 EST

Commit a5d90c923bcf ("x86/efi: Quirk out SGI UV") added a quirk to
efi_apply_memmap_quirks to force SGI UV systems to fall back to the old
EFI memmap mechanism. We have a BIOS fix for this issue now, so we no
longer need this quirk in the kernel. This commit removes the quirk
from the function in question.
