From c7258d2010e6d979180fc0365c5e087ddba026eb Mon Sep 17 00:00:00 2001 From: Jan Stancek Date: Wed, 25 Feb 2026 20:30:23 +0100 Subject: [PATCH] x86/boot: Handle relative CONFIG_EFI_SBAT_FILE file paths commit 3d1973a0c76a78a4728cff13648a188ed486cf44 upstream. CONFIG_EFI_SBAT_FILE can be a relative path. When compiling using a different output directory (O=) the build currently fails because it can't find the filename 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.
