Subject: [PATCH 0/8] arm64: String function updates
Date: Tue, 11 May 2021 17:12:30 +0100	[thread overview]
Message-ID: <cover.1620738177.git.robin.murphy@arm.com> (raw)

Hi all,

Since Oli's last attempt[1], the usercopy story has evolved and diverged
even more, to the point where the shared template idea no longer really
makes sense. While we rethink that, I've split out the straightforward
library function updates so those at least don't have to wait any longer.

Of course in the meantime things haven't stood still there either, with
Cortex Strings being no more, so I've cosmetically refreshed the
remaining original patches to match their new upstream state. I've also
added some tweaks to a couple more functions that just kind of happened
while I was looking at the whole area - arguably the final patch belongs
with the future patches tackling usercopy, but I've thrown it in here
anyway because it's already done.

Robin.
