  efi: Fix handling of multiple efi_fake_mem= entries (2020-01-13 10:41:53 +0100)

----------------------------------------------------------------
Third and final batch of EFI updates for v5.6:
- A few touchups for the x86 libstub changes that have already been queued
  up.
- Fix memory leaks and crash bugs in the EFI fake_mem driver, which may be
  used more heavily in the future for device-dax soft reservation (Dan)
- Avoid RWX mappings in the EFI page tables when possible.
- Avoid PCIe probing failures if the EFI framebuffer is probed first when
  the new of_devlink feature is active.
- Move the support code for the old EFI memory mapping style into its only
  user, the SGI UV1+ support code.

----------------------------------------------------------------
