The VPU_JSM_MSG_CONTEXT_DELETE will remove any resources associated
with the SSID, that included any blobs create by the user space
application.
The command can also remove doorbell registrations, but since this
does not work in HW scheduling case, we do not depend on this
capability and unregister the doorbells explicitly.

At the moment, accel drivers can be built-in even with CONFIG_DRM=m,
but this causes a link failure:
x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_dev_init':

ivpu_drv.c:(.text+0x1fef): undefined reference to `__devm_drm_dev_alloc'
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.

Once we create the handle, the handle owns the reference. Currently
nothing was doing anything with the shmem ptr after the handle was
created, but let's change drm_gem_shmem_create_with_handle() to not
return the pointer, so-as to not encourage problematic use of this
function in the future. As a bonus, it makes the code a bit cleaner.

Due to holidays we started -next with more -fixes in-flight than
usual, and people have been asking where they are. Backmerge to get
things better in sync.
Conflicts:
- Tiny conflict in drm_fbdev_generic.c between variable rename and
missing error handling that got added.
- Conflict in drm_fb_helper.c between the added call to vgaswitcheroo
in drm_fb_helper_single_fb_probe and a refactor patch that extracted
lots of helpers and incidentally removed the dev local variable.
Readd it to make things compile.

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 7efc3b7261030da79001c00d92bc3392fd6c664c.
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 7efc3b726103 ("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.

If st_uid/st_gid doesn't have a mapping in the mounter's user_ns, then
copy-up should fail, just like it would fail if the mounter task was doing
the copy using "cp -a".
There's a corner case where the "cp -a" would succeed but copy up fail: if
there's a mapping of the invalid uid/gid (65534 by default) in the user
namespace. This is because stat(2) will return this value if the mapping
doesn't exist in the current user_ns and "cp -a" will in turn be able to
create a file with this uid/gid.
This behavior would be inconsistent with POSIX ACL's, which return -1 for
invalid uid/gid which result in a failed copy.
For consistency and simplicity fail the copy of the st_uid/st_gid are
invalid.

Drain requests all go through io_drain_req, which has a quick exit in case
there is nothing pending (ie the drain is not useful). In that case it can
run the issue the request immediately.
However for safety it queues it through task work.
The problem is that in this case the request is run asynchronously, but
the async work has not been prepared through io_req_prep_async.
This has not been a problem up to now, as the task work always would run
before returning to userspace, and so the user would not have a chance to
race with it.
However - with IORING_SETUP_DEFER_TASKRUN - this is no longer the case and
the work might be defered, giving userspace a chance to change data being
referred to in the request.
Instead _always_ prep_async for drain requests, which is simpler anyway
and removes this issue.

Following line should listen for a rising edge and exit after the first
one since '-c 1' is provided.
# gpio-event-mon -n gpiochip1 -o 0 -r -c 1
It works with kernel 4.19 but it doesn't work with 5.10. In 5.10 the
above command doesn't exit after the first rising edge it keep listening
for an event forever. The '-c 1' is not taken into an account.
The problem is in commit 62757c32d5db ("tools: gpio: add multi-line
monitoring to gpio-event-mon").
Before this commit the iterator 'i' in monitor_device() is used for
counting of the events (loops). In the case of the above command (-c 1)
we should start from 0 and increment 'i' only ones and hit the 'break'
statement and exit the process. But after the above commit counting
doesn't start from 0, it start from 1 when we listen on one line.
It is because 'i' is used from one more purpose, counting of lines
(num_lines) and it isn't restore to 0 after following code
for (i = 0; i < num_lines; i++)
gpiotools_set_bit(&values.mask, i);
Restore the initial value of the iterator to 0 in order to allow counting
of loops to work for any cases.
