ARM: renumber bits related to _TIF_WORK_MASK

stable inclusion
from stable-v5.10.163
commit 9620f8a5c72f57074ac09d5e392de89f0c02d60a
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7PJ9N

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=9620f8a5c72f57074ac09d5e392de89f0c02d60a



----------------------------------------------------

commit 191f8453 upstream.

We want to ensure that the mask related to calling do_work_pending()
is within the first 16 bits. Move bits unrelated to that outside of
that range, to avoid spuriously calling do_work_pending() when we don't
need to.
