Subject: linux-next: manual merge of the efi tree with the tip tree

Hi all,

Today's linux-next merge of the efi tree got a conflict in:

  arch/x86/boot/compressed/efi_thunk_64.S

between commit:

  cb8bda8ad443 ("x86/boot/compressed: Rename efi_thunk_64.S to efi-mixed.S")

from the tip tree and commit:

  a61962d8e7d3 ("efi: libstub: Permit mixed mode return types other than efi_status_t")

from the efi tree.

I fixed it up (I remofved the file and applied the following patch) and
can carry the fix as necessary. This is now fixed as far as linux-next
is concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.
