The latest that I have is here, though not yet submitted since I needed
to solve one issue on a specific platform with a lot of memory:
Can you share your branch as well? I did not pick all of Arnd's patches
since some appeared to be seemingly independent from KASan on ARM. This
is the KASAN related options that are set in my configuration:
grep KASAN build/linux-custom/.config
CONFIG_HAVE_ARCH_KASAN=y
CONFIG_CC_HAS_KASAN_GENERIC=y
CONFIG_KASAN=y
CONFIG_KASAN_GENERIC=y
CONFIG_KASAN_OUTLINE=y
# CONFIG_KASAN_INLINE is not set
CONFIG_KASAN_STACK=1
CONFIG_TEST_KASAN=m
are you using something different by any chance?
