MAINTAINERS: Daniel for drm co-maintainer

lkml and Linus gained a CoC, and it's serious this time. Which means
my no 1 reason for declining to officially step up as drm maintainer
is gone, and I didn't find any new good excuse.

I chatted with a few people in private already, and the biggest
concern is that I mislay my community hat and start running around
with my intel hat only. Or some other convenient abuse of trust.

That's why this patch doesn't just need a lot of acks that mean "yeah
seems fine to me", but a lot of acks that mean "yeah we'll tell you
when you're over the line and usurp you from that comfy chair if you
don't get it". Which I think we've been done a fairly good job here at
dri-devel in general, but better to be clear.

Rough idea is that I'll do this for maybe 2-3 years, helping Dave
figure out a group model for drm overall. And getting the tooling and
infrastructure for that off the ground. Then step down again because
some other shiny thing that needs chasing. Of course as plans tend to
do, this one will probably pan out a bit different in reality.

avoid complications by not assuming per-engine isolation.

ceph: make 'nocopyfrom' a default mount option

until the issue is fixed.

Thus, this patch adds the 'nocopyfrom' mount option to the default mount

backlight: pwm_bl: Fix brightness levels for non-DT case.

Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED
linearly to human eye")' allows the possibility to compute a default
brightness table when there isn't the brightness-levels property in the
DT. Unfortunately the changes made broke the pwm backlight for the
non-DT boards.

Usually, the non-DT boards don't pass the brightness levels via platform
data, instead, it sets the max_brightness in their platform data and the
driver calculates the level without a table. The offending patch assumed
that when there is no brightness levels table we should create one, but this
is clearly wrong for the non-DT case.

After this patch the code handles the DT and the non-DT case taking in
consideration also if max_brightness is set or not.

powerpc/mm: Fallback to RAM if the altmap is unusable

The "altmap" is used to provide a pool of memory that is reserved for
the vmemmap backing of hot-plugged memory. This is useful when adding
large amount of ZONE_DEVICE memory to a system with a limited amount of
normal memory.

On ppc64 we use huge pages to map the vmemmap which requires the backing
storage to be contigious and aligned to the hugepage size. The altmap
implementation allows for the altmap provider to reserve a few PFNs at
the start of the range for it's own uses and when this occurs the
first chunk of the altmap is not usable for hugepage mappings. On hash
there is no sane way to fall back to a normal sized page mapping so we
fail the allocation. This results in memory hotplug failing with
ENOMEM when the new range doesn't fall into an existing vmemmap block.

This patch handles this case by falling back to using system memory
rather than failing if we cannot allocate from the altmap. This
fallback should only ever be used for the first vmemmap block so it
should not cause excess memory consumption.

powerpc/papr_scm: Use ibm,unit-guid as the iset cookie

The interleave set cookie is used to determine if a label stored in the

important in the case of NVDIMMs since the firmware may change the

cookie to be non-zero.

For our purposes we just need the set cookie to be unique and fixed for
a given PAPR SCM region and using the unit-guid (really a UUID) is fine

powerpc/papr_scm: Fix DIMM device registration race

When a new nvdimm device is registered with libnvdimm via
nvdimm_create() it is added as a device on the nvdimm bus. The probe
function for the DIMM driver is potentially quite slow so actually
registering and probing the device is done in an async domain rather
than immediately after device creation. This can result in a race where
the region device (created 2nd) is probed first and fails to activate at
boot.

To fix this we use the same approach as the ACPI/NFIT driver which is to
check that all the DIMM devices registered successfully. LibNVDIMM
provides the nvdimm_bus_count_dimms() function which synchronises with
the async domain and verifies that the dimm was successfully registered
with the bus.

If either of these does not occur then we bail.
