04a789bef3 drm/amd/display: add stream ID and otg instance in dc_stream_state
[why]
stream ID allows DMs to avoid memory address comparisons to compare
stream equality.
otg_instance allows DC to more rigorously define when otg_instance
can change.  specifically, it is now defined to be only mutable when dc_stream_state
changes.  This is better than a "get status" function which prevents efficient
caching of otherwise very stable information.

[how]
stream ID follows similar pattern to sink ID, which is already implemented

otg_instance is an output which occurs on all dc_stream modification functions

923fe49512 drm/amd/display: Detach backlight from stream
[Why]
Backlight is conceptually a property of links, not streams.
All backlight programming is done on links, but there is a
stream property bl_pwm_level that is used to restore backlight
on dpms on and s3 resume.  This is unnecessary, as backlight
is already restored by hardware with no driver intervention.

[How]
Remove bl_pwm_level, and the stream argument to set_backlight

ceb3dbb469 drm/amd/display: remove sink reference in dc_stream_state
[why]
dc_stream_state containing a pointer to sink is poor design.
Sink describes the display, and the specifications or capabilities
it has.  That information is irrelevant for dc_stream_state, which describes
hardware state, and is generally used for hardware programming.  It
could further be argued that dc_sink itself is just a convenience dc
provides, and DC should be perfectly capable of programming hardware
without any dc_sinks (for example, emulated sinks).

[how]
Phase 1:
Deprecate use of dc_sink pointer in dc_stream.  Most references are trivial
to remove, but some call sites are risky (such as is_timing_changed) with
no obvious logical replacement.  These will be removed in follow up change.

Add dc_link pointer to dc_stream.  This is the typical reason DC really needed
sink pointer, and most call sites are replaced with this.

DMs also need minor updates, as all 3 DMs leverage stream->sink for
some functionality.  this is replaced instead by a pointer to private data
inside dc_stream_state, which is used by DMs as a quality of life improvment
for some key functionality.  it allows DMs to set pointers have to their own objects
which associate OS objects to dc_stream_states (such as DisplayTarget
and amdgpu_dm_connector).  Without the private pointer, DMs would be
forced to perform a lookup for callbacks.

ef32bc1c75 drm/amd/display: Fix issue with VLine interrupt not firing
[Why]
We are not correctly handling the wrap around case.
VLine interrupt is relative to position of VUpdate interrupt.

Both VUpdate interrupt and VLine interrupt could possibly
be in front porch or back porch.

[How]
Fix wraparound case by checking for line number that is
greater than the VTOTAL of the OTG timing. In this case,
the interrupt should occur on the next frame.

Also fix some variable naming and remove some dead code.

96d4f267e4 Remove 'type' argument from access_ok() function
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.

It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access.  But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.

A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model.  And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.

This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.

There were a couple of notable cases:

 - csky still had the old "verify_area()" name as an alias.

 - the iter_iov code had magical hardcoded knowledge of the actual
   values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
   really used it)

 - microblaze used the type argument for a debug printout

but other than those oddities this should be a total no-op patch.

I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something.  Any missed conversion should be trivially fixable, though.

5d6527a784 mm/mmu_notifier: use structure for invalidate_range_start/end callback
Patch series "mmu notifier contextual informations", v2.

This patchset adds contextual information, why an invalidation is
happening, to mmu notifier callback.  This is necessary for user of mmu
notifier that wish to maintains their own data structure without having to
add new fields to struct vm_area_struct (vma).

For instance device can have they own page table that mirror the process
address space.  When a vma is unmap (munmap() syscall) the device driver
can free the device page table for the range.

Today we do not have any information on why a mmu notifier call back is
happening and thus device driver have to assume that it is always an
munmap().  This is inefficient at it means that it needs to re-allocate
device page table on next page fault and rebuild the whole device driver
data structure for the range.

Other use case beside munmap() also exist, for instance it is pointless
for device driver to invalidate the device page table when the
invalidation is for the soft dirtyness tracking.  Or device driver can
optimize away mprotect() that change the page table permission access for
the range.

This patchset enables all this optimizations for device drivers.  I do not
include any of those in this series but another patchset I am posting will
leverage this.

The patchset is pretty simple from a code point of view.  The first two
patches consolidate all mmu notifier arguments into a struct so that it is
easier to add/change arguments.  The last patch adds the contextual
information (munmap, protection, soft dirty, clear, ...).

This patch (of 3):

To avoid having to change many callback definition everytime we want to
add a parameter use a structure to group all parameters for the
mmu_notifier invalidate_range_start/end callback.  No functional changes
with this patch.

9705bea5f8 mm: convert zone->managed_pages to atomic variable
totalram_pages, zone->managed_pages and totalhigh_pages updates are
protected by managed_page_count_lock, but readers never care about it.
Convert these variables to atomic to avoid readers potentially seeing a
store tear.

This patch converts zone->managed_pages.  Subsequent patches will convert
totalram_panges, totalhigh_pages and eventually managed_page_count_lock
will be removed.

Main motivation was that managed_page_count_lock handling was complicating
things.  It was discussed in length here,
https://lore.kernel.org/patchwork/patch/995739/#1181785 So it seemes
better to remove the lock and convert variables to atomic, with preventing
poteintial store-to-read tearing as a bonus.
