This reverts commit: aeffc492 ("x86/efi: Request desired alignment via the PE/COFF headers") Linn reports that Signtool complains that kernels built with CONFIG_EFI_STUB=y are violating the PE/COFF specification because the 'SizeOfImage' field is not a multiple of 'SectionAlignment'. This violation was introduced as an optimisation to skip having the kernel relocate itself during boot and instead have the firmware place it at a correctly aligned address. No one else has complained and I'm not aware of any firmware implementations that refuse to boot with commit aeffc492, but it's a real bug, so revert the offending commit. Reported-by:
