   - Xen EFI support - Daniel Kiper

   - Support for autoloading the efivars driver - Lee, Chun-Yi

   - Use the PE/COFF headers in the x86 EFI boot stub to request that
     the stub be loaded with CONFIG_PHYSICAL_ALIGN alignment - Michael
     Brown

   - Consolidate all the x86 EFI quirks into one file - Saurabh Tangri

   - Additional error logging in x86 EFI boot stub - Ulf Winkelvos

   - Support loading initrd above 4G in EFI boot stub - Yinghai Lu

   - EFI reboot patches for ACPI hardware reduced platforms"
