Subject: [PATCH 0/2] Make capsules in a contiguous virtual space

Recently we found it failed to update firmware through capsule update
mechanism in linux-4.14 and later version.

After some investigation, the reason is firmware expects capsules in a
contiguous virtual space and this assumption is not satisfied in recent
linux versions.

Ge Song (2):
  Revert "efi/capsule-loader: Use page addresses rather than struct page
    pointers"
  efi/capsule-loader: Request a contiguous virtual space for capsules
