Merge emailed patches from Peter Xu:
"This is a small series that I picked up from Linus's suggestion to
simplify cow handling (and also make it more strict) by checking
against page refcounts rather than mapcounts.
This makes uffd-wp work again (verified by running upmapsort)"
Note: this is horrendously bad timing, and making this kind of
fundamental vm change after -rc3 is not at all how things should work.
The saving grace is that it really is a a nice simplification:
8 files changed, 29 insertions(+), 120 deletions(-)
The reason for the bad timing is that it turns out that commit
17839856fd58 ("gup: document and work around 'COW can break either way'
issue" broke not just UFFD functionality (as Peter noticed), but Mikulas
Patocka also reports that it caused issues for strace when running in a
DAX environment with ext4 on a persistent memory setup.
And we can't just revert that commit without re-introducing the original
issue that is a potential security hole, so making COW stricter (and in
the process much simpler) is a step to then undoing the forced COW that
broke other uses.

With the more strict (but greatly simplified) page reuse logic in
do_wp_page(), we can safely go back to the world where cow is not
enforced with writes.
This essentially reverts commit 17839856fd58 ("gup: document and work
around 'COW can break either way' issue"). There are some context
differences due to some changes later on around it:
2170ecfa7688 ("drm/i915: convert get_user_pages() --> pin_user_pages()", 2020-06-03)
376a34efa4ee ("mm/gup: refactor and de-duplicate gup_fast() code", 2020-06-03)
Some lines moved back and forth with those, but this revert patch should
have striped out and covered all the enforced cow bits anyways.

With the intel_modeset_* probe functions clarified, we can continue with
moving more related calls to the right layer:

When using 128-bit interrupt-remapping table entry (IRTE) (a.k.a GA mode),
current driver disables interrupt remapping when it updates the IRTE
so that the upper and lower 64-bit values can be updated safely.
However, this creates a small window, where the interrupt could
arrive and result in IO_PAGE_FAULT (for interrupt) as shown below.
IOMMU Driver Device IRQ
============ ===========
irte.RemapEn=0
...
change IRTE IRQ from device ==> IO_PAGE_FAULT !!
...
irte.RemapEn=1
This scenario has been observed when changing irq affinity on a system
running I/O-intensive workload, in which the destination APIC ID
in the IRTE is updated.
Instead, use cmpxchg_double() to update the 128-bit IRTE at once without
disabling the interrupt remapping. However, this means several features,
which require GA (128-bit IRTE) support will also be affected if cmpxchg16b
is not supported (which is unprecedented for AMD processors w/ IOMMU).

We can sometimes get bogus thermal shutdowns on omap4430 at least with
droid4 running idle with a battery charger connected:
thermal thermal_zone0: critical temperature reached (143 C), shutting down
Dumping out the register values shows we can occasionally get a 0x7f value
that is outside the TRM listed values in the ADC conversion table. And then
we get a normal value when reading again after that. Reading the register
multiple times does not seem help avoiding the bogus values as they stay
until the next sample is ready.
Looking at the TRM chapter "18.4.10.2.3 ADC Codes Versus Temperature", we
should have values from 13 to 107 listed with a total of 95 values. But
looking at the omap4430_adc_to_temp array, the values are off, and the
end values are missing. And it seems that the 4430 ADC table is similar
to omap3630 rather than omap4460.
Let's fix the issue by using values based on the omap3630 table and just
ignoring invalid values. Compared to the 4430 TRM, the omap3630 table has
the missing values added while the TRM table only shows every second
value.
Note that sometimes the ADC register values within the valid table can
also be way off for about 1 out of 10 values. But it seems that those
just show about 25 C too low values rather than too high values. So those
do not cause a bogus thermal shutdown.

The VT-d spec requires (10.4.4 Global Command Register, GCMD_REG General
Description) that:
If multiple control fields in this register need to be modified, software
must serialize the modifications through multiple writes to this register.
However, in irq_remapping.c, modifications of IRE and CFI are done in one
write. We need to do two separate writes with STS checking after each. It
also checks the status register before writing command register to avoid
unnecessary register write.

To be used in order to create foreign mappings. This is based on the
ZONE_DEVICE facility which is used by persistent memory devices in
order to create struct pages and kernel virtual mappings for the IOMEM
areas of such devices. Note that on kernels without support for
ZONE_DEVICE Xen will fallback to use ballooned pages in order to
create foreign mappings.
The newly added helpers use the same parameters as the existing
{alloc/free}_xenballooned_pages functions, which allows for in-place
replacement of the callers. Once a memory region has been added to be
used as scratch mapping space it will no longer be released, and pages
returned are kept in a linked list. This allows to have a buffer of
pages and prevents resorting to frequent additions and removals of
regions.
If enabled (because ZONE_DEVICE is supported) the usage of the new
functionality untangles Xen balloon and RAM hotplug from the usage of
unpopulated physical memory ranges to map foreign pages, which is the
correct thing to do in order to avoid mappings of foreign pages depend
on memory hotplug.
Note the driver is currently not enabled on Arm platforms because it
would interfere with the identity mapping required on some platforms.

A couple of minor fixes to the display changes that went in for 5.9.
The most important of which is a workaround for a HW bug that was
exposed by better push buffer space management, leading to
random(ish...) display engine hangs.

If tg3_reset_task() fails, the device state is left in an inconsistent
state with IFF_RUNNING still set but NAPI state not enabled. A
subsequent operation, such as ifdown or AER error can cause it to
soft lock up when it tries to disable NAPI state.
Fix it by bringing down the device to !IFF_RUNNING state when
tg3_reset_task() fails. tg3_reset_task() running from workqueue
will now call tg3_close() when the reset fails. We need to
modify tg3_reset_task_cancel() slightly to avoid tg3_close()
calling cancel_work_sync() to cancel tg3_reset_task(). Otherwise
cancel_work_sync() will wait forever for tg3_reset_task() to
finish.

Enable multi-ring ih1 and ih2 for Arcturus only.
For Navi10 family multi-ring has been disabled.
Apparently, having multi-ring enabled in Navi was causing
continus page fault interrupts.

drm_dev_alloc() alloc *dev* and set managed.final_kfree to dev to free
itself.
Now from commit 5cdd68498918("drm/amdgpu: Embed drm_device into
amdgpu_device (v3)") we alloc *adev* and ddev is just a member of it.
So drm_dev_release try to free a wrong pointer then.
Also driver's release trys to free adev, but drm_dev_release will
access dev after call drvier's release.
To fix it, remove driver's release and set managed.final_kfree to adev.
