Subject: [RFC PATCH 0/7] Move 64e to new interrupt return code
Date: Mon,  8 Mar 2021 19:52:36 +1000	[thread overview]
Message-ID: <20210308095244.3195782-1-npiggin@gmail.com> (raw)

Time to finally try removing the remaining old cruft left over
from the big interrupt return rewrite in C.

This series will clash lightly with Christophe's one to switch
ppc32 over. His should go in first because it's a lot bigger
and more mature at this stage. I will rebase this series on top
of his at some point but at the moment it's just based on upstream.

Patch 1 should go in as a fix, patch 5 is not required for this
series I'll drop it from non-rfc series and send it separately (it's
not tested at the moment).

Thanks,
Nick
