ARM: renumber bits related to _TIF_WORK_MASK
commit 191f8453fc99a537ea78b727acea739782378b0d upstream.
conflicts with the preempt-lazy patches from the -rt folks, resulting
in some post merge duplicates and compile failures like:
arch/arm/include/asm/thread_info.h:141: error: "TIF_NOTIFY_SIGNAL" redefined
[-Werror]
Ideally I would have copied the thread_info directly from the v5.15-rt
branch of linux-stable-rt[1] so that we'd stay exactly aligned with -rt
upstream for when/if we integrate future updates from the preempt-rt
people, but they haven't yet integrated the v5.15.87 with the offending
change yet.
