Merge the gup_flags cleanups from Lorenzo Stoakes:
"This patch series adjusts functions in the get_user_pages* family such
that desired FOLL_* flags are passed as an argument rather than
implied by flags.
The purpose of this change is to make the use of FOLL_FORCE explicit
so it is easier to grep for and clearer to callers that this flag is
being used. The use of FOLL_FORCE is an issue as it overrides missing
VM_READ/VM_WRITE flags for the VMA whose pages we are reading
from/writing to, which can result in surprising behaviour.
The patch series came out of the discussion around commit 38e0885465
("mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing"),
which addressed a BUG_ON() being triggered when a page was faulted in
with PROT_NONE set but having been overridden by FOLL_FORCE.
do_numa_page() was run on the assumption the page _must_ be one marked
for NUMA node migration as an actual PROT_NONE page would have been
dealt with prior to this code path, however FOLL_FORCE introduced a
situation where this assumption did not hold.
See
https://marc.info/?l=linux-mm&m=147585445805166
for the patch proposal"
Additionally, there's a fix for an ancient bug related to FOLL_FORCE and
FOLL_WRITE by me.
[ This branch was rebased recently to add a few more acked-by's and
reviewed-by's ]
* gup_flag-cleanups:
mm: replace access_process_vm() write parameter with gup_flags
mm: replace access_remote_vm() write parameter with gup_flags
mm: replace __access_remote_vm() write parameter with gup_flags
mm: replace get_user_pages_remote() write/force parameters with gup_flags
mm: replace get_user_pages() write/force parameters with gup_flags
mm: replace get_vaddr_frames() write/force parameters with gup_flags
mm: replace get_user_pages_locked() write/force parameters with gup_flags
mm: replace get_user_pages_unlocked() write/force parameters with gup_flags
mm: remove write/force parameters from __get_user_pages_unlocked()
mm: remove write/force parameters from __get_user_pages_locked()
mm: remove gup_flags FOLL_WRITE games from __get_user_pages()
This removes the 'write' and 'force' from get_user_pages() and replaces
them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers
as use of this flag can result in surprising behaviour (and hence bugs)
within the mm subsystem.

drm/amdgpu: remove DRM_AMD_POWERPLAY
drm/radeon: Prevent races on pre DCE4 between flip submission and completion.
drm/radeon: Slightly more robust flip completion handling for < DCE-4
Pre DCE4 hw doesn't have reliable pageflip completion
interrupts, so instead polling for flip completion is
used from within the vblank irq handler to complete
page flips.
This causes a race if pageflip ioctl is called close to
vblank:
1. pageflip ioctl queues execution of radeon_flip_work_func.
2. vblank irq fires, radeon_crtc_handle_vblank checks for
flip_status == FLIP_SUBMITTED finds none, no-ops.
3. radeon_flip_work_func runs inside vblank, decides to
set flip_status == FLIP_SUBMITTED and programs the
flip into hw.
4. hw executes flip immediately (because in vblank), but
as 2 already happened, the flip completion routine only
emits the flip completion event one refresh later ->
wrong vblank count/timestamp for completion and no
performance gain, as instead of delaying the flip until
next vblank, we now delay the next flip by 1 refresh
while waiting for the delayed flip completion event.
Given we often don't gain anything due to this race, but
lose precision, prevent the programmed flip from executing
in vblank on pre DCE4 asics to avoid this race.
On pre-AVIVO hw we can't program the hw for edge-triggered
flips, they always execute anywhere in vblank. Therefore delay
the actual flip programming until after vblank on pre-AVIVO.

Pre DCE4 hardware doesn't have (reliable) pageflip completion
irqs, therefore we have to use the old polling method for flip
completion handling in vblank irq.
As vblank irqs fire a bit before start of vblank (when the
linebuffer fifo read position reaches end of scanout), we
have some fudge for flip completion handling in the last
lines of active scanout. Old code assumed the threshold to
be 99% of active scanout height, a ballpark estimate which
worked ok. Since we know since a while how to calculate the
actual threshold from linebuffer size, lets make use of it
to get a more accurate threshold.
This completion path is still prone to some races in corner
cases, especially on pre-AVIVO hardware, so document them
a bit better in the code comments.

Rather than using "struct file*", use "struct drm_file*" as tag VM tag for
BOs. This will pave the way for "struct drm_file*" without any "struct
file*" back-pointer.

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/radeon/radeon_device.c:1961:5: warning: no previous prototype for 'radeon_debugfs_init' [-Wmissing-prototypes]
drivers/gpu/drm/radeon/radeon_device.c:1966:6: warning: no previous prototype for 'radeon_debugfs_cleanup' [-Wmissing-prototypes]
In fact, these functions are dummy, but can be removed,
so this patch removes them.

Normally on shutdown or reboot we don't care about necessarily
making sure the hw is in a good state because the system is about
to be powered down or reset. However, after a shutdown or reboot
in a VM, it's best to tear down the hw properly otherwise there
can be problems with the next VM use.

First drm-next pull for radeon and amdgpu for 4.9. Highlights:
- powerplay support for iceland asics
- improved GPU reset (both full asic and per block)
- UVD and VCE powergating for CZ and ST
- VCE clockgating for CZ and ST
- Support for pre-initialized (e.g., zeroed) vram buffers
- ttm cleanups
- virtual display support
- core and radeon/amdgpu support for page_flip_target
- lots of bug fixes and clean ups

Replace packet2's with packet0 writes to UVD_NO_OP. The
value written to UVD_NO_OP does not matter.

Writes to this register are the preferred way to do NOPs.
