It will get reverted. I've Cc:-ed Matt. My guess would be one of these two EFI commits: * Fix early boot regression affecting x86 EFI boot stub when loading initrds above 4GB - Yinghai Lu 47226ad4f4cf x86/efi: Only load initrd above 4g on second try * Relocate GOT entries in the x86 EFI boot stub now that we have symbols with global visibility - Matt Fleming 9cb0e394234d x86/efi: Fixup GOT in all boot code paths If it's 9cb0e394234d - then it's perhaps a build quirk, or a bug in the assembly code. If so then we'd have to revert this, and reintroduce another regression, caused by EFI commit f23cf8bd5c1f49 in this merge window. The most recent commit is easy to revert, the older one not. If it's 47226ad4f4cf then we'd reintroduce the regression caused by 4bf7111f501 in the previous merge window. They both revert cleanly after each other - but it might be safer to just revert the most recent one. My guess is that your regression is caused by 47226ad4f4cf. Sorry about this, the timing is unfortunate.
