Subject: [GIT PULL] EFI changes for v5.8
Ingo, Thomsd, Boris,
Please pull the changes below. Note that I did not incorporate the GOT
handling changes for the x86 decompressor - Arvind has some changes on
top that might just as well go in at the same time, and they are not
really EFI changes anyway.
The following changes since commit 4da0b2b7e67524cc206067865666899bc02e1cb0:
efi/libstub: Re-enable command line initrd loading for x86 (2020-04-25 12:26:32 +0200)
are available in the Git repository at:
