The downstream code from which this was derived didn't ever run through
this 'switch' block with non-AFBC formats, but the upstream code does --
we use this function to probe whether a given format is supported.

Demote the warning to eliminate this sort of warning seen on every
boot:

  [drm] unsupported AFBC format[3231564e]

And make it warn more than once, because if we *actually* care to see
what formats we're probing/rejecting and for what reasons, we probably
care about more than just the first message.

Drop the comment, because one of the two *is* commonly reachable.

And lastly, drop the unreachable return; we'd do better to let the
compiler complain if we start hitting this unexpectedly.

types at the moment, the current code is safe. However, in order

The unprepare sequence has started to fail after moving to panel bridge
code in the msm drm driver (commit 007ac026 ("drm/msm/dsi: switch to
DRM_PANEL_BRIDGE")). You'll see messages like this in the kernel logs:

   panel-boe-tv101wum-nl6 ae94000.dsi.0: failed to set panel off: -22

This is because boe_panel_enter_sleep_mode() needs an operating DSI link
to set the panel into sleep mode. Performing those writes in the
unprepare phase of bridge ops is too late, because the link has already
been torn down by the DSI controller in post_disable, i.e. the PHY has
been disabled, etc. See dsi_mgr_bridge_post_disable() for more details
on the DSI .

Split the unprepare function into a disable part and an unprepare part.
For now, just the DSI writes to enter sleep mode are put in the disable
function. This fixes the panel off routine and keeps the panel happy.

My Wormdingler has an integrated touchscreen that stops responding to
touch if the panel is only half disabled too. This patch fixes it. And
finally, this saves power when the screen is off because without this
fix the regulators for the panel are left enabled when nothing is being
displayed on the screen.

At the moment, accel drivers can be built-in even with CONFIG_DRM=m,
but this causes a link failure:

The problem is that DRM_ACCEL is a 'bool' symbol, so driver that
only depend on DRM_ACCEL but not also on DRM do not see the restriction
to =m configs.

To ensure that each accel driver has an implied dependency on CONFIG_DRM,
enclose the entire Kconfig file in an if/endif check.

Merge tag 'drm-habanalabs-next-2023-01-26' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next

This tag contains habanalabs driver and accel changes for v6.3:

- Moved the driver to the accel subsystem. Currently only the files were
  moved (including the uapi file which was also renamed). This doesn't
  include registering to the accel subsystem. This will probably be only
  in the next kernel version.

- In case of decoder error (axi error) in Gaudi2, we can now find the exact
  IP that initiated the erroneous transaction and print the details for
  better debug.

- Add more trace events. We now can trace mmio transactions and communication
  with the preboot firmware.

- Add to Gaudi2 support for abrupt reset that is done by the firmware. This
  was support so far only for Gaudi1.

- Add uAPI to flush memory transactions (to the device memory). This is
  needed by the communications library in case of doing p2p with a host NIC
  which access our HBM directly through the PCI BAR.

- Add uAPI to pass-through a request from user-space to firmware and get the
  result back to user-space. This will allow the driver code to avoid the
  need to add new packet (in the communication channel with the firmware) for
  every new request type.

- Remove the option to export dma-buf by memory allocation handle in our uAPI.
  This was planned for Gaudi2 but was never used. Instead, we will do export
  by memory address (same as Gaudi1). In addition, we added the option to
  specify an offset to the address. This is needed in Gaudi2 because there
  the user allocates the entire HBM in one allocation, but would like to
  export only small part of it.

- Multiple bug fixes, refactors and small optimizations.

This reverts commit 7efc3b72.

We have got openSUSE reports (Link 1) for 6.1 kernel with khugepaged
stalling CPU for long periods of time.  Investigation of tracepoint data
shows that compaction is stuck in repeating fast_find_migrateblock()
based migrate page isolation, and then fails to migrate all isolated
pages.

Commit 7efc3b72 ("mm/compaction: fix set skip in fast_find_migrateblock")
was suspected as it was merged in 6.1 and in theory can indeed remove a
termination condition for fast_find_migrateblock() under certain
conditions, as it removes a place that always marks a scanned pageblock
from being re-scanned.  There are other such places, but those can be
skipped under certain conditions, which seems to match the tracepoint
data.

Testing of revert also appears to have resolved the issue, thus revert
the commit until a more robust solution for the original problem is
developed.

It's also likely this will fix qemu stalls with 6.1 kernel reported in
Link 2, but that is not yet confirmed.

Joe found another DT file that shouldn't be executable, and that
frustrated me enough that I went hunting with this script:

    git ls-files -s |
        grep '^100755' |
        cut -f2 |
        xargs grep -L '^#!'

and that found another file that shouldn't have been marked executable
either, despite being in the scripts directory.

Maybe these two are the last ones at least for now.  But I'm sure we'll
be back in a few years, fixing things up again.
