Cover letter [MODERATED] [PATCH 0/9] TAA 0
From: Borislav Petkov <[email protected]>
Subject: [PATCH 0/9] TAA
Hi,
here's the pile I've picked up. I've incorporated as much of the feedback as possible, scream loudly if something's missing. First testing looks good.
We'll cast them in stone in the coming days because distros and stable have to start backporting soon. All fixes will go ontop, as in previous occasions.
Thx.
