With the current code, we use tlbiel_pwc() for doing a pwc flush.
and that does what is done this patch. May be we can update this patch
such that we drop tlbiel_pwc and switch all those instance to
tlbiel_pid(pid, RIC_FLUSH_PWC) ?

You already do this in a later patch.

Right, I do it in a later latch and I prefer to keep it this way, to
avoid doing too many changes in a single patch.

The commit message do indicate that we don't do flushing correctly for
PWC flush with the current code. That is not correct. May be update the
commit message then ?
