[PATCH RFC v2 15/19] export __wake_on_current_cpu

[Bernd Schubert <bschubert@xxxxxxx>]

This is needed by fuse-over-io-uring to wake up the waiting
application thread on the core it was submitted from.
Avoiding core switching is actually a major factor for
fuse performance improvements of fuse-over-io-uring.
