--- Comment #42 from cbaylis at gcc dot gnu.org --- While we're suggesting fixes to the kernel, wouldn't it be better if CONFIG_ARM64_ERRATUM_843419 forced the kernel to be built with the linker workarounds if the kernel is configured KBUILD_LDFLAGS += --fix-cortex-a53-843419 or maybe KBUILD_LDFLAGS += $(call ld-option, --fix-cortex-a53-843419)
