covers cases when we have a local adjusted_mode variable, and doesn't

aad941d53f drm/i915: Always use crtc_ timings when dealing with adjustead_mode
The adjustead_mode crtc_ timings are what we will program into the hardware,
so it's those timings we should be looking practically everywhere.

The normal and crtc_ timings should differ only when stere doubling is
used. In that case the normal timings are the orignal non-doubled
timigns, and crtc_ timings are the doubled timings used by the hardware.

The only case where we continue to look at the normal timings is when we
pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC.
drm_edid keeps the modes aronund in the non-double form only, so it
needs the non-double timings to match against.

Done with sed
's/adjusted_mode->\([vhVH]\)/adjusted_mode->crtc_\1/g'
's/adjusted_mode->clock/adjusted_mode->crtc_clock/g'
with a manual s/VDisplay/vdisplay/ within the comment in intel_dvo.c

08aef7caa1 drm/i915/skl: Block disable call for pw1 if dmc firmware is present.
Another interesting criteria to work dmc as expected is pw1 to be
enabled by driver and dmc will shut it off in its execution
sequence. If already disabled by driver dmc will get confuse and
behave differently than expected found during pc10 entry issue
for skl.

So berfore we disable power-well 1, added check if dmc firmware is
present and driver will not disable power well 1, but for any reason
if firmware is not present of failed to load we can shut off the
power well 1 which will save some power.

As skl is currently fully dependent on dmc to go in lowest possible
power state (dc6) but the same is not applicable for bxt. Display
engine can enter into dc9 without dmc, hence unblocking disable call.

v1: Initial version.

v2: Rebased as per current patch series.

4b7ab5fca1 drm/i915/skl: Added a check for the hardware status of csr fw before loading.
Dmc will restore the csr program except DC9, cold boot,
warm reset, PCI function level reset, and hibernate/suspend.

intel_csr_load_program() function is used to load the firmware
data from kernel memory to csr address space.

All values of csr address space will be zero if it got reset and
the first byte of csr program is always a non-zero if firmware
is loaded successfuly. Based on hardware status will load the
firmware.

Without this condition check if we overwrite the firmware data the
counters exposed for dc5/dc6 (help for debugging) will be nullified.

Note: Above commit message seems to be confused and the real problem
apparently going on is that for suspend-to-idle and system standby the
firmware survives (it's like runtime pm), but it doesn't for
suspend-to-mem and hibernate-to-disk. All the other talking about DC9
and pci reset are irrelevant for the path touched here (only driver
load and system resume functions) and might not be true statements.

v1: Initial version.

v2: Based on review comments from Daniel,
- Added a check to know hardware status and load the firmware if not loaded.

This was seen on vmware esxi hypervisor. When passing the graphics device

 "This includes a iser-target series from Jenny + Sagi @ Mellanox that
  addresses the few remaining active I/O shutdown bugs, along with a
  patch to support zero-copy for immediate data payloads that gives a
  nice performance improvement for small block WRITEs.

  Also included are some recent >= v4.2 regression bug-fixes.  The most
  notable is a RCU conversion regression for SPC-3 PR registrations, and
  recent removal of obsolete RFC-3720 markers that introduced a login
  regression bug with MSFT iSCSI initiators.

  Thanks to everyone who has been testing + reporting bugs for v4.x"

673681cafa iscsi-target: Avoid OFMarker + IFMarker negotiation
This patch fixes a v4.2+ regression introduced by commit c04a6091
that removed support for obsolete sync-and-steering markers usage
as originally defined in RFC-3720.

The regression would involve attempting to send OFMarker=No +
IFMarker=No keys during opertional negotiation login phase,
including when initiators did not actually propose these keys.

The result for MSFT iSCSI initiators would be random junk in
TCP stream after the last successful login request was been sent
signaling the move to full feature phase (FFP) operation.

To address this bug, go ahead and avoid negotiating these keys
by default unless the initiator explicitly proposes them, but
still respond to them with 'No' if they are proposed.
