Subject: 8139cp: revert "set ring address before enabling receiver"
From: Francois Romieu <romieu@fr.zoreil.com>
commit b26623dab7eeb1e9f5898c7a49458789dd492f20 upstream.
This patch reverts b01af4579ec41f48e9b9c774e70bd6474ad210db.
The original patch was tested with emulated hardware. Real
hardware chokes.

Subject: [PATCH 2/3] drm/radeon: properly handle mc_stop/mc_resume on
evergreen+ (v2)
Upstream commit 62444b7462a2b98bc78d68736c03a7c4e66ba7e2
- Stop the displays from accessing the FB
- Block CPU access
- Turn off MC client access
This should fix issues some users have seen, especially
with UEFI, when changing the MC FB location that result
in hangs or display corruption.
v2: fix crtc enabled check noticed by Luca Tettamanti

Subject: [PATCH 3/3] drm/radeon: properly track the crtc not_enabled case
evergreen_mc_stop()
Upstream commit 804cc4a0ad3a896ca295f771a28c6eb36ced7903
The save struct is not initialized previously so explicitly
mark the crtcs as not used when they are not in use.
