xtensa: fix build with KASAN
The commit 917538e212a2 ("kasan: clean up KASAN_SHADOW_SCALE_SHIFT usage") removed KASAN_SHADOW_SCALE_SHIFT definition from include/linux/kasan.h and added it to architecture-specific headers, except for xtensa. This broke the xtensa build with KASAN enabled. Define KASAN_SHADOW_SCALE_SHIFT in arch/xtensa/include/asm/kasan.h Reported by: kbuild test robot <fengguang.wu@intel.com> Fixes: 917538e212a2 ("kasan: clean up KASAN_SHADOW_SCALE_SHIFT usage") Acked-by: Andrey Konovalov <andreyknvl@google.com> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
