Subject: [PATCH v3 0/5] efi: Support ESRT under Xen

This patch series fixes handling of EFI tables when running under Xen.
These fixes allow the ESRT to be loaded when running paravirtualized in
dom0, making the use of EFI capsule updates possible.

Demi Marie Obenour (5):
  efi: memmap: Disregard bogus entries instead of returning them
  efi: xen: Implement memory descriptor lookup based on hypercall
  efi: Apply allowlist to EFI configuration tables when running under
    Xen
  efi: Actually enable the ESRT under Xen
  efi: Warn if trying to reserve memory under Xen
