Subject: [PATCH v2 0/5] shoot lazy tlbs

From: Nicholas Piggin <[email-masked]>
Date: Mon, 14 Dec 2020 16:53:07 +1000

This is another rebase, on top of mainline now (don't need the
asm-generic tree), and without any x86 or membarrier changes.
This makes the series far smaller and more manageable and
without the controversial bits.

Thanks,
Nick
