Pull drm fixes from Daniel Vetter:
"Dave is back in shape, but now family got it so I'm doing the pull.
Two things worthy of note:
- nouveau feature pull was way too late, Dave&me decided to not take
that, so Ben spun up a pull with just the fixes.
- after some chatting with the arm display maintainers we decided to
change a bit how that's maintained, for more oversight/review and
cross vendor collab.
More details below:
nouveau:
- bugfixes
- TU116 enabling (minor iteration) :w
amdgpu:
- large pile of fixes for new hw support this release (navi, vega20)
- audio hotplug fix
- bunch of corner cases and small fixes all over for amdgpu/kfd
komeda:
- back out some new properties (from this merge window) that needs
more pondering.
bochs:
- fb pitch setup
core:
- a new panel quirk
- misc fixes"

Merge yet more updates from Andrew Morton:
"The rest of MM and a kernel-wide procfs cleanup.
Summary of the more significant patches:
- Patch series "mm/memory_hotplug: Factor out memory block
devicehandling", v3. David Hildenbrand.
Some spring-cleaning of the memory hotplug code, notably in
drivers/base/memory.c
- "mm: thp: fix false negative of shmem vma's THP eligibility". Yang
Shi.
Fix /proc/pid/smaps output for THP pages used in shmem.
- "resource: fix locking in find_next_iomem_res()" + 1. Nadav Amit.
Bugfix and speedup for kernel/resource.c
- Patch series "mm: Further memory block device cleanups", David
Hildenbrand.
More spring-cleaning of the memory hotplug code.
- Patch series "mm: Sub-section memory hotplug support". Dan
Williams.
Generalise the memory hotplug code so that pmem can use it more
completely. Then remove the hacks from the libnvdimm code which
were there to work around the memory-hotplug code's constraints.
- "proc/sysctl: add shared variables for range check", Matteo Croce.
We have about 250 instances of
int zero;
...
.extra1 = &zero,
in the tree. This is a tree-wide sweep to make all those private
"zero"s and "one"s use global variables.
Alas, it isn't practical to make those two global integers const"

mm: migrate: remove unused mode argument
mm/sparsemem: cleanup 'section number' data types

In the function alps_is_cs19_trackpoint(), we check if the param[1] is
in the 0x20~0x2f range, but the code we wrote for this checking is not
correct:
(param[1] & 0x20) does not mean param[1] is in the range of 0x20~0x2f,
it also means the param[1] is in the range of 0x30~0x3f, 0x60~0x6f...
Now fix it with a new condition checking ((param[1] & 0xf0) == 0x20).

The keyboard and trackpad on recent MacBook's (since 8,1) and
MacBookPro's (13,* and 14,*) are attached to an SPI controller instead
of USB, as previously. The higher level protocol is not publicly
documented and hence has been reverse engineered. As a consequence there
are still a number of unknown fields and commands. However, the known
parts have been working well and received extensive testing and use.
In order for this driver to work, the proper SPI drivers need to be
loaded too; for MB8,1 these are spi_pxa2xx_platform and spi_pxa2xx_pci;
for all others they are spi_pxa2xx_platform and intel_lpss_pci.

In nouveau_conn_reset(), if connector->state is true,
__drm_atomic_helper_connector_destroy_state() will be called,
but the memory pointed by asyc isn't freed. Memory leak happens
in the following function __drm_atomic_helper_connector_reset(),
where newly allocated asyc->state will be assigned to connector->state.
So using nouveau_conn_atomic_destroy_state() instead of
__drm_atomic_helper_connector_destroy_state to free the "old" asyc.
Here the is the log showing memory leak.

It turns out that while disabling i2c bus access from software when the
GPU is suspended was a step in the right direction with:
commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")
We also ended up accidentally breaking the vbios init scripts on some
older Tesla GPUs, as apparently said scripts can actually use the i2c
bus. Since these scripts are executed before initializing any
subdevices, we end up failing to acquire access to the i2c bus which has
left a number of cards with their fan controllers uninitialized. Luckily
this doesn't break hardware - it just means the fan gets stuck at 100%.
This also means that we've always been using our i2c busses before
initializing them during the init scripts for older GPUs, we just didn't
notice it until we started preventing them from being used until init.
It's pretty impressive this never caused us any issues before!
So, fix this by initializing our i2c pad and busses during subdev
pre-init. We skip initializing aux busses during pre-init, as those are
guaranteed to only ever be used by nouveau for DP aux transactions.

Higher layers tend to add a lot of modes not actually in the EDID, such
as the standard DMT modes. Changing this would be extremely intrusive to
everyone, so just force the scaler more often. There are no practical
cases we're aware of where a LVDS/eDP panel has multiple resolutions
exposed, and i915 already does it this way.

In the sysctl code the proc_dointvec_minmax() function is often used to
validate the user supplied value between an allowed range. This
function uses the extra1 and extra2 members from struct ctl_table as
minimum and maximum allowed value.
On sysctl handler declaration, in every source file there are some
readonly variables containing just an integer which address is assigned
to the extra1 and extra2 members, so the sysctl range is enforced.
The special values 0, 1 and INT_MAX are very often used as range
boundary, leading duplication of variables like zero=0, one=1,
int_max=INT_MAX in different source files:
$ git grep -E '\.extra[12].*&(zero|one|int_max)' |wc -l
248
Add a const int array containing the most commonly used values, some
macros to refer more easily to the correct array member, and use them
instead of creating a local one for every object file.

At namespace creation time there is the potential for the "expected to
be zero" fields of a 'pfn' info-block to be filled with indeterminate
data. While the kernel buffer is zeroed on allocation it is immediately
overwritten by nd_pfn_validate() filling it with the current contents of
the on-media info-block location. For fields like, 'flags' and the
'padding' it potentially means that future implementations can not rely on
those fields being zero.
In preparation to stop using the 'start_pad' and 'end_trunc' fields for
section alignment, arrange for fields that are not explicitly
initialized to be guaranteed zero. Bump the minor version to indicate
it is safe to assume the 'padding' and 'flags' are zero. Otherwise,
this corruption is expected to benign since all other critical fields
are explicitly initialized.
Note The cc: stable is about spreading this new policy to as many
kernels as possible not fixing an issue in those kernels. It is not
until the change titled "libnvdimm/pfn: Stop padding pmem namespaces to
section alignment" where this improper initialization becomes a problem.
So if someone decides to backport "libnvdimm/pfn: Stop padding pmem
namespaces to section alignment" (which is not tagged for stable), make
sure this pre-requisite is flagged.

pfns
walk_memory_range() was once used to iterate over sections. Now, it
iterates over memory blocks. Rename the function, fixup the
documentation.
Also, pass start+size instead of PFNs, which is what most callers
already have at hand. (we'll rework link_mem_sections() most probably
soon)
Follow-up patches will rework, simplify, and move walk_memory_blocks()
to drivers/base/memory.c.
Note: walk_memory_blocks() only works correctly right now if the
start_pfn is aligned to a section start. This is the case right now,
but we'll generalize the function in a follow up patch so the semantics
match the documentation.

This patch (of 6):
We are using a mixture of "int" and "unsigned long". Let's make this
consistent by using "unsigned long" everywhere. We'll do the same with
memory block ids next.
While at it, turn the "unsigned long i" in removable_show() into an int

We really don't want anything during memory hotunplug to fail. We
always pass a valid memory block device, that check can go. Avoid
allocating memory and eventually failing. As we are always called under
lock, we can use a static piece of memory. This avoids having to put
the structure onto the stack, having to guess about the stack size of
callers.
Patch inspired by a patch from Oscar Salvador.
In the future, there might be no need to iterate over nodes at all.
mem->nid should tell us exactly what to remove. Memory block devices
with mixed nodes (added during boot) should properly fenced off and
never removed.

Let's factor out removing of memory block devices, which is only
necessary for memory added via add_memory() and friends that created
memory block devices. Remove the devices before calling
arch_remove_memory().
This finishes factoring out memory block device handling from
arch_add_memory() and arch_remove_memory().

Only memory to be added to the buddy and to be onlined/offlined by user
space using /sys/devices/system/memory/... needs (and should have!)
memory block devices.
Factor out creation of memory block devices. Create all devices after
arch_add_memory() succeeded. We can later drop the want_memblock
parameter, because it is now effectively stale.
Only after memory block devices have been added, memory can be onlined
by user space. This implies, that memory is not visible to user space
at all before arch_add_memory() succeeded.
While at it
- use WARN_ON_ONCE instead of BUG_ON in moved unregister_memory()
- introduce find_memory_block_by_id() to search via block id
- Use find_memory_block_by_id() in init_memory_block() to catch
duplicates

We want to improve error handling while adding memory by allowing to use
arch_remove_memory() and __remove_pages() even if
CONFIG_MEMORY_HOTREMOVE is not set to e.g., implement something like:
arch_add_memory()
rc = do_something();
if (rc) {
arch_remove_memory();
}
We won't get rid of CONFIG_MEMORY_HOTREMOVE for now, as it will require
quite some dependencies for memory offlining.

Unlike legacy chips, 57500 chips don't need additional VNIC resources
for aRFS/ntuple. Fix the code accordingly so that we don't reserve
and allocate additional VNICs on 57500 chips. Without this patch,
the driver is failing to initialize when it tries to allocate extra
VNICs.

Pull more device mapper updates from Mike Snitzer:
- Fix zone state management race in DM zoned target by eliminating the
unnecessary DMZ_ACTIVE state.
- A couple fixes for issues the DM snapshot target's optional discard
support added during first week of the 5.3 merge.
- Increase default size of outstanding IO that is allowed for a each
dm-kcopyd client and introduce tunable to allow user adjust.
- Update DM core to use printk ratelimiting functions rather than
duplicate them and in doing so fix an issue where DMDEBUG_LIMIT()
rate limited KERN_DEBUG messages had excessive "callbacks suppressed"
messages.

[WHY] dc sw clock implementation of navi10 and raven are not exact the
same. dcccg, dchub reference clock initialization is done after dc calls
vbios dispcontroller_init table. for raven family, before
dispcontroller_init is called by dc, the ref clk values are referred
by sw clock implementation and program asic register using wrong
values. this causes dchub pstate error. This need provide valid ref
clk values. for navi10, since dispcontroller_init is not called,
dchubbub_global_timer_enable = 0, hubbub2_get_dchub_ref_freq will
hit aeert. this need remove hubbub2_get_dchub_ref_freq from this
location and move to dcn20_init_hw.
[HOW] for all asic, initialize dccg, dchub ref clk with data from
vbios firmware table by default. for raven asic family, use these data
from vbios, for asic which support sw dccg component, like navi10,
read ref clk by sw dccg functions and update the ref clk.
