From: Ard Biesheuvel <ardb@xxxxxxxxxx>
Hello Linus,
Please pull the EFI fix below. It fixes an oversight on my part in the recent
EFI stub rework for x86, which is needed to get Linux/x86 distro builds signed
again for secure boot by MicroSoft. For this reason, most of this work is being
backported to v6.1, which is therefore also affected by this regression.
Thanks,
Ard.

x86/efistub: Clear decompressor BSS in native EFI entrypoint (2024-03-15 19:47:09 +0100)
----------------------------------------------------------------
EFI fixes for v6.9 #1
- Explicitly wipe BSS in the native EFI entrypoint, so that globals
shared with the legacy decompressor are zero-initialized correctly.
