Can you guide me through the steps please?
I done:
1. cd /usr/src/linux
2. sudo git pull
3. then I applied your patch.
Am I doing something wrong?
/usr/src/linux> cat .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

merge = refs/heads/master
[remote "stable"]
url = https://kernel.googlesource.com/pub/scm/linux/kernel/git/stable/linux-stable
fetch = +refs/heads/*:refs/remotes/stable/*
I am pulling from the "master" branch.

1. git log shows "d2d11f342b179f1894a901f143ec7c008caba43e"
2. No, no patches on top.
3. I am doing the following steps:
/usr/src/linux> sudo git reset --hard origin/master

Hi Dave,
thanks a lot. I was able to reproduce the problem and get it fixed by

NV_ARCH', but the firmware display remains active. Applies cleanly to
drm-tip BTW.
