Date: Sun May 31 2015 - 12:26:32 EST

Hi folks,

Please pull the following new material for v4.2. The most interesting
change is support for the EFI System Resource Table contributed by Peter
Jones. ESRT is new in the UEFI 2.5 specification (released April 2015)
and is used by Fedora's fwupdate tool when performing firmware updates.

The following changes since commit b787f68c36d49bb1d9236f403813641efa74a031:
