With VHE and nVHE executable code completely separated, remove build config that disabled GCOV/KASAN/UBSAN/KCOV instrumentation for VHE as these now execute under the same memory mappings as the rest of the kernel. No violations are currently being reported by either KASAN or UBSAN. Signed-off-by: David Brazdil <dbrazdil@google.com> --- arch/arm64/kvm/hyp/Makefile | 8 -------- 1 file changed, 8 deletions(-)
