Subject: [PATCH 0/3] Hook up qspinlock for arm64
Date: Tue, 26 Jun 2018 12:00:09 +0100	[thread overview]
Message-ID: <1530010812-17161-1-git-send-email-will.deacon@arm.com> (raw)

Hi everybody,

With my recent changes to the core qspinlock code, it now performs well
enough on arm64 to replace our ticket-based approach.

Testing welcome,

Will
