My master is up to date with security/next.

Still get the same result:

$ git am -3 ~/Downloads/v3-4-5-efi-call-get_event_log-before-ExitBootServices.patch
Applying: efi: call get_event_log before ExitBootServices
error: sha1 information is lacking or useless (drivers/firmware/efi/efi.c).
error: could not build fake ancestor
Patch failed at 0001 efi: call get_event_log before ExitBootServices
The copy of the patch that failed is found in: .git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

Maybe you have some other trees fetched in your local GIT so that it
finds the ancestors? Anyway, cannot test this at this point.
