Commit b0f847e16c1e ("HID: hid-sensor-hub: Force logical minimum to 1 for
power and report state") not only replaced the descriptor fixup done for
devices with the HID_SENSOR_HUB_ENUM_QUIRK with a generic fix, but also
accidentally removed the unrelated descriptor fixup for the Lenovo ThinkPad
Helix 2 sensor hub. This commit restores this fixup.
Restoring this fixup not only fixes the Lenovo ThinkPad Helix 2's sensors,
but also the Lenovo ThinkPad 8's sensors.

There is a NULL pointer dereference in case memory resources

Use the new of_get_compatible_child() helper to lookup the slot child
node instead of using of_find_compatible_node(), which searches the
entire tree from a given start node and thus can return an unrelated
(i.e. non-child) node.
This also addresses a potential use-after-free (e.g. after probe
deferral) as the tree-wide helper drops a reference to its first
argument (i.e. the node of the device being probed).
While at it, also fix up the related slot-node reference leak.

"crtc->helper_private" is not initialized by the QXL driver and thus the
"crtc_funcs->disable" call would crash (resulting in suspend failure).
Fix this by converting the suspend/resume functions to use the
drm_mode_config_helper_* helpers.
Tested system sleep with QEMU 3.0 using "echo mem > /sys/power/state".
During suspend the following message is visible from QEMU:
spice/server/display-channel.c:2425:display_channel_validate_surface: canvas address is 0x7fd05da68308 for 0 (and is NULL)
spice/server/display-channel.c:2426:display_channel_validate_surface: failed on 0
This seems to be triggered by QXL_IO_NOTIFY_CMD after
QXL_IO_DESTROY_PRIMARY_ASYNC, but aside from the warning things still
seem to work (tested with both the GTK and -spice options).

Within show_valid_zones() the function test_pages_in_a_zone() should be
called for online memory blocks only.
Otherwise it might lead to the VM_BUG_ON due to uninitialized struct
pages (when CONFIG_DEBUG_VM_PGFLAGS kernel option is set):
page dumped because: VM_BUG_ON_PAGE(PagePoisoned(p))

That VM_BUG_ON was triggered by the page poisoning introduced in
mm/sparse.c with the git commit d0dc12e86b31 ("mm/memory_hotplug:
optimize memory hotplug").
With the same commit the new 'nid' field has been added to the struct
memory_block in order to store and later on derive the node id for
offline pages (instead of accessing struct page which might be
uninitialized). But one reference to nid in show_valid_zones() function
has been overlooked. Fixed with current commit. Also, nr_pages will
not be used any more after test_pages_in_a_zone() call, do not update
it.

The current code grabs the private_data of whatever file descriptor
userspace has supplied and implicitly casts it to a `struct ucma_file *`,
potentially causing a type confusion.
This is probably fine in practice because the pointer is only used for
comparisons, it is never actually dereferenced; and even in the
comparisons, it is unlikely that a file from another filesystem would have
a ->private_data pointer that happens to also be valid in this context.
But ->private_data is not always guaranteed to be a valid pointer to an
object owned by the file's filesystem; for example, some filesystems just
cram numbers in there.
Check the type of the supplied file descriptor to be safe, analogous to how
other places in the kernel do it.

If the previous modeset commit has completed and is no longer part of
the crtc state, skip waiting for it.
Ville pointed out that, in fact, the commit is never removed after a
modeset so the only way we could see a NULL here should be if there was
never a commit attached. Nevertheless, we have the evidence it can be
NULL and it has been defended against elsewhere, for example commit
93313538c153 ("drm/i915: Pass idle crtc_state to intel_dp_sink_crc").

commit f07b3c1da92d ("HID: generic: create one input report per
application type") was effectively the same as MULTI_INPUT:
hidinput->report was never set, so hidinput_match_application()
always returned null.
Fix that by testing against the real application.
Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT
instead of HID_QUIRK_INPUT_PER_APP. Enable this quirk for backward
compatibility on all non-Win8 touchscreens.

resist any temptation to flood the kernel logs with their errors.
Relegate the DRM_ERROR to a DRM_DEBUG so the user has to opt into

attached to the task, so that the concerned process can inspect its own

Since commit d1ac3ff008fb ("dm verity: switch to using asynchronous hash

so that it can use hardware with asynchronous processing of crypto
operations.
These asynchronous calls don't support vmalloc memory, but the buffer data
can be allocated with vmalloc if dm-bufio is short of memory and uses a
reserved buffer that was preallocated in dm_bufio_client_create().

There are two issues with the current RPCS programming for Icelake:
Expansion of the slice count bitfield has been missed, as well as the
required programming workaround for the subslice count bitfield size
limitation.
1)
Bitfield width for configuring the active slice count has grown so we need
to program the GEN8_R_PWR_CLK_STATE accordingly.
Current code was always requesting eight times the number of slices (due
writing to a bitfield starting three bits higher than it should). These
requests were luckily a) capped by the hardware to the available number of
slices, and b) we haven't yet exported the code to ask for reduced slice
configurations.
Due both of the above there was no impact from this incorrect programming
but we should still fix it.
2)
Due subslice count bitfield being only three bits wide and furthermore
capped to a maximum documented value of four, special programming
workaround is needed to enable more than four subslices.
With this programming driver has to consider the GT configuration as
2x4x8, while the hardware internally translates this to 1x8x8.
A limitation stemming from this is that either a subslice count between
one and four can be selected, or a subslice count equaling the total
number of subslices in all selected slices. In other words, odd subslice
counts greater than four are impossible, as are odd subslice counts
greater than a single slice subslice count.
This also had no impact in the current code base due breakage from 1)
always reqesting more than one slice.
While fixing this we also add some asserts to flag up any future bitfield
overflows.
v2:
* Use a local in all branches for clarity. (Lionel)

Continuing the fun of trying to find exactly the delay that is
sufficient to ensure that the page directory is fully loaded between
context switches, move the extra flush added in commit 70b73f9ac113
("drm/i915/ringbuffer: Delay after invalidating gen6+ xcs") to just

Handle guest mm access life cycle properly with mmget()/mmput().
As noted by Linus, use_mm() depends on valid live page table but
KVM's mmgrab() doesn't guarantee that. As vGPU usage depends on
guest VM life cycle, need to make sure to use mmget()/mmput() to
guarantee VM address access.
v3: fix build
v2: v1 caused a weird dependence issue which failed for vfio
device release, which result invalid mdev vgpu and kvm state
without proper release taken. This trys to put right reference
around VM address space access instead.

Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number
of MSIX vectors used by RDMA. There is one code path in open that needs
to check the true max_cp_rings including any used by RDMA. This code
is now checking for the reduced max_cp_rings which will fail when the
number of cp rings is very small.
To fix this in a clean way, we don't adjust max_cp_rings anymore.
Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the
reduced max_cp_rings when appropriate.

When the driver detects that resources have changed during open, it
should reset the rx and tx rings to 0. This will properly setup the
init sequence to initialize the default rings again. We also need
to signal the RDMA driver to stop and clear its interrupts. We then
call the RoCE driver to restart if a new set of default rings is
successfully reserved.

Older gen use a physical address for the hardware status page, for which
we use cache-coherent writes. As the writes are into the cpu cache, we use
a normal WB mapped page to read the HWS, used for our seqno tracking.
Anecdotally, I observed lost breadcrumbs writes into the HWS on i965gm,
which so far have not reoccurred with this patch. How reliable that
evidence is remains to be seen.
v2: Explicitly pass the expected physical address to the hw
v3: Also remember the wild writes we once had for HWS above 4G.

We currently assert that if the target is in a CPU write domain, we use
a CPU reloc path rather than the GPU reloc path. However, we have a debug
override to force the GPU path and that unfortunately hits the assert.
Include the async clflush under the debug option to ensure correct
behaviour even when debugging, and strict when not.
