Linus Walleij ef21187c06 ARM: 9430/1: entry: Do a dummy read from VMAP shadow ... commit 44e9a3bb76 upstream. When switching task, in addition to a dummy read from the new VMAP stack, also do a dummy read from the VMAP stack's corresponding KASAN shadow memory to sync things up in the new MM context.
