Subject: [PATCH 0/3] sparc32 SRMMU fixes for SMP
Date: Tue, 26 May 2020 18:32:59 +0100
Message-ID: <20200526173302.377-1-will@kernel.org> (raw)

Hi folks,

Enabling SMP for sparc32 uncovered some issues in the SRMMU page-table
allocation code. One of these was introduced by me, but the other two
seem to have been there a while and are probably just exposed more
easily by my recent changes.

Tested on QEMU. I'm assuming these will go via David's tree.

Cheers,

Will
