Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds

The link pass will correct the specific cases that both clang and gcc now generate. Signed-off-by: Jeremy Linton <redacted> --- arch/arm64/Kconfig | 6 ------ 1 file changed, 6 deletions(-)
