b57aa47d39 drm/gem: Test for imported GEM buffers with helper
Add drm_gem_is_imported() that tests if a GEM object's buffer has
been imported. Update the GEM code accordingly.

GEM code usually tests for imports if import_attach has been set
in struct drm_gem_object. But attaching a dma-buf on import requires
a DMA-capable importer device, which is not the case for many serial
busses like USB or I2C. The new helper tests if a GEM object's dma-buf
has been created from the GEM object.

Add a number of helpers for shrinking that access core TTM and

f3bcfd04a5 drm/ttm: Add a macro to perform LRU iteration
Following the design direction communicated here:

https://lore.kernel.org/linux-mm/b7491378-defd-4f1c-31e2-29e4c77e2d67@amd.com/T/#ma918844aa8a6efe8768fdcda0c6590d5c93850c9

Export a LRU walker for driver shrinker use. The walker
initially supports only trylocking, since that's the
method used by shrinkes. The walker makes use of
scoped_guard() to allow exiting from the LRU walk loop
without performing any explicit unlocking or
cleanup.

v8:
- Split out from another patch.
- Use a struct for bool arguments to increase readability (Matt Brost).
- Unmap user-space cpu-mappings before shrinking pages.
- Explain non-fatal error codes (Matt Brost)

v10:
- Instead of using the existing helper, Wrap the interface inside out and
  provide a loop to de-midlayer things the LRU iteration (Christian König).
- Removing the R-B by Matt Brost since the patch was significantly changed.

v11:
- Split the patch up to include just the LRU walk helper.

v12:
- Indent after scoped_guard() (Matt Brost)

v15:
- Adapt to new definition of scoped_guard()

b63d715b80 drm/ttm/pool, drm/ttm/tt: Provide a helper to shrink pages
Provide a helper to shrink ttm_tt page-vectors on a per-page
basis. A ttm_backup backend could then in theory get away with
allocating a single temporary page for each struct ttm_tt.

This is accomplished by splitting larger pages before trying to
back them up.

In the future we could allow ttm_backup to handle backing up
large pages as well, but currently there's no benefit in
doing that, since the shmem backup backend would have to
split those anyway to avoid allocating too much temporary
memory, and if the backend instead inserts pages into the
swap-cache, those are split on reclaim by the core.

Due to potential backup- and recover errors, allow partially swapped
out struct ttm_tt's, although mark them as swapped out stopping them
from being swapped out a second time. More details in the ttm_pool.c
DOC section.

v2:
- A couple of cleanups and error fixes in ttm_pool_back_up_tt.
- s/back_up/backup/
- Add a writeback parameter to the exported interface.
v8:
- Use a struct for flags for readability (Matt Brost)
- Address misc other review comments (Matt Brost)
v9:
- Update the kerneldoc for the ttm_tt::backup field.
v10:
- Rebase.
v13:
- Rebase on ttm_backup interface change. Update kerneldoc.
- Rebase and adjust ttm_tt_is_swapped().
v15:
- Rebase on ttm_backup return value change.
- Rebase on previous restructuring of ttm_pool_alloc()
- Rework the ttm_pool backup interface (Christian König)
- Remove cond_resched() (Christian König)
- Get rid of the need to allocate an intermediate page array
  when restoring a multi-order page (Christian König)
- Update documentation.

d05386a3fd drm/print: require struct drm_device for drm_err() and friends
The expectation is that the struct drm_device based logging helpers get
passed an actual struct drm_device pointer rather than some random
struct pointer where you can dereference the ->dev member.

Add a static inline helper to convert struct drm_device to struct
device, with the main benefit being the type checking of the macro
argument.

As a side effect, this also reduces macro argument double references.

drm/tests: Drop drm_kunit_helper_acquire_ctx_alloc()
lockdep complains when a lock is released in a separate thread the
lock is taken in, and it turns out that kunit does run its actions in a
separate thread than the test ran in.

This means that drm_kunit_helper_acquire_ctx_alloc() just cannot work as
it's supposed to, so let's just get rid of it.

a6ba2dad0a drivers: base: component: add function to query the bound status
The component helpers already expose the bound status in debugfs, but at
times it might be necessary to also check that state in the kernel and
act differently depending on the result.

For example the shutdown handler of a drm-driver might need to stop
a whole output pipeline if the drm device is up and running, but may
run into problems if that drm-device has never been set up before,
for example because the binding deferred.

So add a little helper that returns the bound status for a componet
device.

5e7715478c drm/dp: Add helper to set LTTPRs in transparent mode
According to the DisplayPort standard, LTTPRs have two operating
modes:
 - non-transparent - it replies to DPCD LTTPR field specific AUX
   requests, while passes through all other AUX requests
 - transparent - it passes through all AUX requests.

Switching between this two modes is done by the DPTX by issuing
an AUX write to the DPCD PHY_REPEATER_MODE register.

Add a generic helper that allows switching between these modes.

Also add a generic wrapper for the helper that handles the explicit
disabling of non-transparent mode and its disable->enable sequence
mentioned in the DP Standard v2.0 section 3.6.6.1. Do this in order
to move this handling out of the vendor specific driver implementation
into the generic framework.

Helper is for scheduler internal use so lets hide it from DRM drivers
completely.

At the same time we change the method of checking whethere there is
anything in the queue from peeking to looking at the node count.

b76f1467dc drm/sched: Remove a hole from struct drm_sched_job
We can re-order some struct members and take u32 credits outside of the
pointer sandwich and also for the last_dependency member we can get away
with an unsigned int since for dependency we use xa_limit_32b.

Pahole report before:
        /* size: 160, cachelines: 3, members: 14 */
        /* sum members: 156, holes: 1, sum holes: 4 */
        /* last cacheline: 32 bytes */

And after:
        /* size: 152, cachelines: 3, members: 14 */
        /* last cacheline: 24 bytes */

6bc7e4eb04 Revert "net: skb: introduce and use a single page frag cache"
After the previous commit is finally safe to revert commit dbae2b0628
("net: skb: introduce and use a single page frag cache"): do it here.

The intended goal of such change was to counter a performance regression
introduced by commit 3226b158e6 ("net: avoid 32 x truesize
under-estimation for tiny skbs").

Unfortunately, the blamed commit introduces another regression for the
virtio_net driver. Such a driver calls napi_alloc_skb() with a tiny
size, so that the whole head frag could fit a 512-byte block.

The single page frag cache uses a 1K fragment for such allocation, and
the additional overhead, under small UDP packets flood, makes the page
allocator a bottleneck.

Thanks to commit bf9f1baa27 ("net: add dedicated kmem_cache for
typical/small skb->head"), this revert does not re-introduce the
original regression. Actually, in the relevant test on top of this
revert, I measure a small but noticeable positive delta, just above
noise level.

The revert itself required some additional mangling due to recent updates
in the affected code.

on kernel built with MAX_SKB_FRAGS=45, where SKB_WITH_OVERHEAD(1024)
is smaller than GRO_MAX_HEAD.

Such built additionally contains the revert of the single page frag cache
so that napi_get_frags() ends up using the page frag allocator, triggering
the splat.

Note that the underlying issue is independent from the mentioned
revert; address it ensuring that the small head cache will fit either TCP
and GRO allocation and updating napi_alloc_skb() and __netdev_alloc_skb()
to select kmalloc() usage for any allocation fitting such cache.

9b6412e697 tcp: drop secpath at the same time as we currently drop dst
Xiumei reported hitting the WARN in xfrm6_tunnel_net_exit while
running tests that boil down to:
 - create a pair of netns
 - run a basic TCP test over ipcomp6
 - delete the pair of netns

The xfrm_state found on spi_byaddr was not deleted at the time we
delete the netns, because we still have a reference on it. This
lingering reference comes from a secpath (which holds a ref on the
xfrm_state), which is still attached to an skb. This skb is not
leaked, it ends up on sk_receive_queue and then gets defer-free'd by
skb_attempt_defer_free.

The problem happens when we defer freeing an skb (push it on one CPU's
defer_list), and don't flush that list before the netns is deleted. In
that case, we still have a reference on the xfrm_state that we don't
expect at this point.

We already drop the skb's dst in the TCP receive path when it's no
longer needed, so let's also drop the secpath. At this point,
tcp_filter has already called into the LSM hooks that may require the
secpath, so it should not be needed anymore. However, in some of those
places, the MPTCP extension has just been attached to the skb, so we
cannot simply drop all extensions.

966a0d49d1 drm/ast: cursor: Move format conversion to shared helper
User-space cursor-image data is encoded in ARBG8888, while hardware
supports ARGB4444. Implement the format conversion as part of the
format-helper framework, so that other drivers can benefit.

This allows to respect the damage area of the cursor update. In
previous code, all cursor image data had to be converted on each
update. Now, only the changed areas require an update. The hardware
image is always updated completely, as it is required for the
checksum update.

The format-conversion helper still contains the old implementation's
optimization of writing 2 output pixels at the same time.

4b5a28b38c net: Add non-RCU dev_getbyhwaddr() helper
Add dedicated helper for finding devices by hardware address when
holding rtnl_lock, similar to existing dev_getbyhwaddr_rcu(). This prevents
PROVE_LOCKING warnings when rtnl_lock is held but RCU read lock is not.

Extract common address comparison logic into dev_addr_cmp().

net_drop_ns() is NULL when CONFIG_NET_NS is disabled.

The next patch introduces a function that increments

As a prep, let's rename and export net_free() to
net_passive_dec() and add net_passive_inc().
