[PATCH] arch/x86: add $(srctree) as include dir for sbat.o

Posted by Jan Stancek 1 month ago

CONFIG_EFI_SBAT_FILE can be a relative path. When compiling with
objdir != srctree the build currently fails because it can't find
the file set in CONFIG_EFI_SBAT_FILE:
    arch/x86/boot/compressed/sbat.S: Assembler messages:
    arch/x86/boot/compressed/sbat.S:6: Error: file not found: kernel.sbat

Add $(srctree) as include dir for sbat.o.

Fixes: 61b57d35396a ("x86/efi: Implement support for embedding SBAT data for x86")
