Subject: [PATCH 0/2] Use named address spaces for percpu data
Date: Wed, 12 Sep 2018 07:44:40 -0700 [thread overview]
Message-ID: <20180912144442.29271-1-willy@infradead.org> (raw)
rth wrote a patch back in 2016 that uses gcc's address space machinery
to improve code generation for percpu accesses. Ingo asked for some
minor changes to be made, but Richard didn't respond. While looking at
something related, I came across them, and asked Richard's permission
to resurrect and resend the patch, with the changes Ingo asked for at
the time.
The important information about why we want these patch is in 1/2.
