Subject: [PATCH -next 0/6] treewide: Remove redundant branch predictions around signal_pending family

Hi,

This series trivially gets rid of users of signal_pending (and family) explicitly
wrapping the call around an unlikely(). It is redundant as internally this is
already done for us via signal_pending() and [__]fatal_signal_pending().

All patches are independent, so I split it up in case folks want to pick up bits
separately.

Compile tested only. Please consider for v4.21.

Thanks!
