Fixes for 4.18. The ACP patch is a bit bigger than I would like
at this point, but it should have gone in long ago, it just fell
through the cracks. The others are pretty small and straight-forward.
- ACP fix for boards with 2 I2S instances
- DP fix for CZ, vega
- Fix for a hybrid graphics laptop
- Fix a resume regression

This was causing problems on a system with a large amount of RAM, where
display push buffers were being fetched incorrectly when placed in high
system memory addresses.
While this commit will resolve the issue on that particular system, the
issue will be avoided completely with another patch to more fully solve
problems with display and large amounts of system memory on Pascal.
It's still probably a good idea to disable this to prevent weird issues
in the future.

[why] dp hbr2 eye diagram pattern for raven asic is not stabled.
workaround is to use tp4 pattern. But this should not be

Currently nouveau doesn't actually expose the state debugfs file that's
usually provided for any modesetting driver that supports atomic, even
if nouveau is loaded with atomic=1. This is due to the fact that the
standard debugfs files that DRM creates for atomic drivers is called
when drm_get_pci_dev() is called from nouveau_drm.c. This happens well
before we've initialized the display core, which is currently
responsible for setting the DRIVER_ATOMIC cap.
So, move the atomic option into nouveau_drm.c and just add the
DRIVER_ATOMIC cap whenever it's enabled on the kernel commandline. This
shouldn't cause any actual issues, as the atomic ioctl will still fail
as expected even if the display core doesn't disable it until later in
the init sequence. This also provides the added benefit of being able to
use the state debugfs file to check the current display state even if
clients aren't allowed to modify it through anything other than the
legacy ioctls.
Additionally, disable the DRIVER_ATOMIC cap in nv04's display core, as
this was already disabled there previously.

When MST and atomic were introduced to nouveau, another structure that
could contain a drm_connector embedded within it was introduced; struct
nv50_mstc. This meant that we no longer would be able to simply loop
through our connector list and assume that nouveau_connector() would
return a proper pointer for each connector, since the assertion that
all connectors coming from nouveau have a full nouveau_connector struct
became invalid.
Unfortunately, none of the actual code that looped through connectors
ever got updated, which means that we've been causing invalid memory
accesses for quite a while now.

When a dce100 asic was suspended, the clocks were not set to 0.

they were found to be the same, and so the clock was not set.

4.18 has the faulty clock assignment in pp_to_dc_clock_levels_with_latency
only, which is only used by Vega. Make sure we multiply these values

we can't borrow the PIPESTAT trick and toggle the enable

Pull ext4 bugfixes from Ted Ts'o:
"Bug fixes for ext4; most of which relate to vulnerabilities where a
maliciously crafted file system image can result in a kernel OOPS or
hang.
At least one fix addresses an inline data bug could be triggered by
userspace without the need of a crafted file system (although it does
require that the inline data feature be enabled)"

Pull cifs fixes from Steve French:
"Five smb3/cifs fixes for stable (including for some leaks and memory
overwrites) and also a few fixes for recent regressions in packet
signing.
Additional testing at the recent SMB3 test event, and some good work

xfstest runs on these, Aurelien and Stefano did additional test runs
to verify this set"
