Hi,

The goal is this patch series is to decouple TWA_SIGNAL based task_work
from real signals and signal delivery. The motivation is speeding up
TWA_SIGNAL based task_work, particularly for threaded setups where
->sighand is shared across threads. See the last patch for numbers.

On top of this I have an arch series that wires up TIF_NOTIFY_SIGNAL
for all archs, and then procedes to kill off the legacy TWA_SIGNAL path,
and the code associated with it.

Changes since v6:
- Rebase to 5.10-rc1
