riscv: Fix asan-stack clang build
Nathan reported that because KASAN_SHADOW_OFFSET was not defined in Kconfig, it prevents asan-stack from getting disabled with clang even when CONFIG_KASAN_STACK is disabled: fix this by defining the corresponding config. Reported-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Alexandre Ghiti <alexandre.ghiti@canonical.com> Fixes: 8ad8b72721d0 ("riscv: Add KASAN support") Cc: stable@vger.kernel.org Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>
