From: Thomas Weißschuh Date: Sat, 22 Mar 2025 09:03:16 +0000 (+0100) Subject: x86: drop unnecessary prefix map configuration X-Git-Tag: v6.15-rc1~11^2~8 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=97282e6d380db8a07120fe1b794ac969ee4a3b5c;p=thirdparty%2Flinux.git x86: drop unnecessary prefix map configuration The toplevel Makefile already provides -fmacro-prefix-map as part of KBUILD_CPPFLAGS. In contrast to the KBUILD_CFLAGS and KBUILD_AFLAGS variables, KBUILD_CPPFLAGS is not redefined in the architecture specific Makefiles. Therefore the toplevel KBUILD_CPPFLAGS do apply just fine, to both C and ASM sources. The custom configuration was necessary when it was added in commit 9e2276fa6eb3 ("arch/x86/boot: Use prefix map to avoid embedded paths") but has since become unnecessary in commit a716bd743210 ("kbuild: use -fmacro-prefix-map for .S sources"). Drop the now unnecessary custom prefix map configuration.
