Tom has asked that I not send emails on each patch when they are
applied to my tree. So in this case I am replying manually on the
cover letter.

For this series:
1. Pulled in the updated commits from Heinrich from -next:

f4bbd7b9faa efi_loader: Separate device path into its own header
f139fbe64b0 efi: Include device-path functions in the EFI API docs
162a6b3df34 efi: Rename END to EFI_DP_END

2. Pulled in the rest of these patches, since they depend on patches
not present / rejected / changes-requested for -next:
5f4327ec9f3 efi: Rename the lib/efi directory
ca1f2dbd8e7 efi: Rename CONFIG_EFI to CONFIG_EFI_CLIENT
a07abd67dac efi: Create a new CONFIG_EFI
c787cb9d278 efi: Update maintainers for EFI_CLIENT
624cdc9228d efi: Move the base name and PXE info into lib/efi
0121164befb efi: Adjust copyright and mention constant source
ed4bb8d9826 efi: Move FDT-filename discovery into lib/efi

Applied to sjg/master, thanks!

Regards,
Simon
