Cover letter [MODERATED] [PATCH 0/9] TAA v2 0
From: Borislav Petkov <[email protected]>
Subject: [PATCH 0/9] TAA v2
Hi,
lemme send the pile out one more time before I leave for OSS EU in Lyon. Patch 6 is still there until Paolo and Tony have figured out what should happen with guests.
changelog:
==========
v1:
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.
