rockchip/drm: vop2: add support for gamma LUT
Add support for gamma LUT in VOP2 driver. The implementation was inspired
by one found in VOP1 driver. Blue and red channels in gamma LUT register
write were swapped with respect to how gamma LUT values are written in
VOP1. Gamma LUT port selection was added before the write of new gamma LUT
table.
If the current SoC is rk356x, check if no other CRTC has gamma LUT enabled
in atomic_check (only one video port can use gamma LUT at a time) and
disable gamma LUT before the LUT table write.
If the current SoC isn't rk356x, "seamless" gamma lut update is performed
similarly to how it was done in the case of RK3399 in VOP1[1]. In seamless
update gamma LUT disable before the write isn't necessary, check if no
other CRTC has gamma LUT enabled is also not necessary, different register
is being used to select gamma LUT port[2] and after setting DSP_LUT_EN bit,
GAMMA_UPDATE_EN bit is set[3].
Gamma size is set and drm color management is enabled for each video port's
CRTC except ones which have no associated device.
Patch was tested on RK3566 (Pinetab2). When using userspace tools
which set eg. constant color temperature no issues were noticed. When
using userspace tools which adjust eg. color temperature the slight screen
flicker is visible probably because of gamma LUT disable needed in the
case of RK356x before gamma LUT write.
Compare behaviour of eg.:
```
gammastep -O 3000
```
To eg.:
```
gammastep -l 53:23 -t 6000:3000
```
In latter case color temperature is slowly adjusted at the beginning which
causes screen to slighly flicker. Then it adjusts every few seconds which
also causes slight screen flicker.

- It does not use drm_helper_probe_detect(), which helps with the

drm/vkms: Remove usage of legacy drm_crtc members
Some members of the drm_crtc structure have been deprecated in favor of
equivalent members in the drm_crtc_state structure. As reported by Ville

commit updates the VKMS driver to use the new drm_crtc_state fields
instead.
Additionally, this commit removes the call to
`drm_calc_timestamping_constants` in `vkms_enable_vblank` as it is
redundant. This calculation is already performed in

drm/bridge: it6505: Fix inverted reset polarity
The IT6505 bridge chip has a active low reset line. Since it is a
"reset" and not an "enable" line, the GPIO should be asserted to
put it in reset and deasserted to bring it out of reset during
the power on sequence.
The polarity was inverted when the driver was first introduced, likely
because the device family that was targeted had an inverting level
shifter on the reset line.
The MT8186 Corsola devices already have the IT6505 in their device tree,
but the whole display pipeline is actually disabled and won't be enabled
until some remaining issues are sorted out. The other known user is
the MT8183 Kukui / Jacuzzi family; their device trees currently do not
have the IT6505 included.
Fix the polarity in the driver while there are no actual users.

mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify()
When the MM_WALK capability is enabled, memory that is mostly accessed by
a VM appears younger than it really is, therefore this memory will be less
likely to be evicted. Therefore, the presence of a running VM can
significantly increase swap-outs for non-VM memory, regressing the
performance for the rest of the system.
Fix this regression by always calling {ptep,pmdp}_clear_young_notify()

mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats
Patch series "mm: multi-gen LRU: Have secondary MMUs participate in
MM_WALK".
Today, the MM_WALK capability causes MGLRU to clear the young bit from
PMDs and PTEs during the page table walk before eviction, but MGLRU does
not call the clear_young() MMU notifier in this case. By not calling this
notifier, the MM walk takes less time/CPU, but it causes pages that are
accessed mostly through KVM / secondary MMUs to appear younger than they
should be.
We do call the clear_young() notifier today, but only when attempting to
evict the page, so we end up clearing young/accessed information less
frequently for secondary MMUs than for mm PTEs, and therefore they appear
younger and are less likely to be evicted. Therefore, memory that is
*not* being accessed mostly by KVM will be evicted *more* frequently,
worsening performance.
ChromeOS observed a tab-open latency regression when enabling MGLRU with a
setup that involved running a VM:
Tab-open latency histogram (ms)
Version p50 mean p95 p99 max
base 1315 1198 2347 3454 10319
mglru 2559 1311 7399 12060 43758
fix 1119 926 2470 4211 6947
This series replaces the final non-selftest patchs from this series[1],
which introduced a similar change (and a new MMU notifier) with KVM
optimizations. I'll send a separate series (to Sean and Paolo) for the
KVM optimizations.
This series also makes proactive reclaim with MGLRU possible for KVM
memory. I have verified that this functions correctly with the selftest
from [1], but given that that test is a KVM selftest, I'll send it with
the rest of the KVM optimizations later. Andrew, let me know if you'd
like to take the test now anyway.

This patch (of 2):
The removed stats, MM_LEAF_OLD and MM_NONLEAF_TOTAL, are not very helpful
and become more complicated to properly compute when adding
test/clear_young() notifiers in MGLRU's mm walk.

Pull scheduler fixes from Thomas Gleixner:
- Plug a race between pick_next_task_fair() and try_to_wake_up() where
both try to write to the same task, even though both paths hold a
runqueue lock, but obviously from different runqueues.
The problem is that the store to task::on_rq in __block_task() is
visible to try_to_wake_up() which assumes that the task is not
queued. Both sides then operate on the same task.
Cure it by rearranging __block_task() so the the store to task::on_rq
is the last operation on the task.
- Prevent a potential NULL pointer dereference in task_numa_work()
task_numa_work() iterates the VMAs of a process. A concurrent unmap
of the address space can result in a NULL pointer return from
vma_next() which is unchecked.
Add the missing NULL pointer check to prevent this.
- Operate on the correct scheduler policy in task_should_scx()
task_should_scx() returns true when a task should be handled by sched
EXT. It checks the tasks scheduling policy.
This fails when the check is done before a policy has been set.
Cure it by handing the policy into task_should_scx() so it operates
on the requested value.
- Add the missing handling of sched EXT in the delayed dequeue
mechanism. This was simply forgotten.

modpost: fix input MODULE_DEVICE_TABLE() built for 64-bit on 32-bit host
When building a 64-bit kernel on a 32-bit build host, incorrect
input MODULE_ALIAS() entries may be generated.
For example, when compiling a 64-bit kernel with CONFIG_INPUT_MOUSEDEV=m
on a 64-bit build machine, you will get the correct output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*r*0,*1,*a*m*l*s*f*w*");

MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*r*a*0,*1,*m*l*s*f*w*");
However, building the same kernel on a 32-bit machine results in
incorrect output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*130,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*16A,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*165,*r*a*0,*1,*18,*1C,*20,*21,*38,*3C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*130,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
A similar issue occurs with CONFIG_INPUT_JOYDEV=m. On a 64-bit build
machine, the output is:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*m*l*s*f*w*");

MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*r*a*m*l*s*f*w*");
However, on a 32-bit machine, the output is incorrect:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*20,*m*l*s*f*w*");

MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*2E0,*r*a*m*l*s*f*w*");
When building a 64-bit kernel, BITS_PER_LONG is defined as 64. However,
on a 32-bit build machine, the constant 1L is a signed 32-bit value.
Left-shifting it beyond 32 bits causes wraparound, and shifting by 31
or 63 bits makes it a negative value.
The fix in commit
e0e92632715f ("[PATCH] PATCH: 1 line 2.6.18 bugfix:
modpost-64bit-fix.patch") is incorrect; it only addresses cases where
a 64-bit kernel is built on a 64-bit build machine, overlooking cases
on a 32-bit build machine.
Using 1ULL ensures a 64-bit width on both 32-bit and 64-bit machines,
avoiding the wraparound issue.

modpost: fix acpi MODULE_DEVICE_TABLE built with mismatched endianness
When CONFIG_SATA_AHCI_PLATFORM=m, modpost outputs incorect acpi
MODULE_ALIAS() if the endianness of the target and the build machine

When the endianness of the target kernel and the build machine match,
the output is correct:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:010601:*");
However, when building a little-endian kernel on a big-endian machine

MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:0601??:*");
The 'cls' and 'cls_msk' fields are 32-bit.
DEF_FIELD() must be used instead of DEF_FIELD_ADDR() to correctly handle
endianness of these 32-bit fields.
The check 'if (cls)' was unnecessary; it never became NULL, as it was
the pointer to 'symval' plus the offset to the 'cls' field.

Input: fix regression when re-registering input handlers
Commit
d469647bafd9 ("Input: simplify event handling logic") introduced
code that would set handler->events() method to either
input_handler_events_filter() or input_handler_events_default() or
input_handler_events_null(), depending on the kind of input handler
(a filter or a regular one) we are dealing with. Unfortunately this
breaks cases when we try to re-register the same filter (as is the case
with sysrq handler): after initial registration the handler will have 2
event handling methods defined, and will run afoul of the check in
input_handler_check_methods():
input: input_handler_check_methods: only one event processing method can be defined (sysrq)
sysrq: Failed to register input handler, error -22
Fix this by adding handle_events() method to input_handle structure and
setting it up when registering a new input handle according to event
handling methods defined in associated input_handler structure, thus
avoiding modifying the input_handler structure.

"The important one is a change to the way in which we handle protection
keys around signal delivery so that we're more closely aligned with
the x86 behaviour, however there is also a revert of the previous fix

materialised shortly afterwards.
I'd love to say we're done with 6.12, but we're aware of some

interrupted context and align our user-visible behaviour with that

mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes
Since commit
efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") a mmap() of anonymous memory without a specific address hint
and of at least PMD_SIZE will be aligned to PMD so that it can benefit
from a THP backing page.
However this change has been shown to regress some workloads
significantly. [1] reports regressions in various spec benchmarks, with
up to 600% slowdown of the cactusBSSN benchmark on some platforms. The
benchmark seems to create many mappings of 4632kB, which would have merged
to a large THP-backed area before commit
efa7df3e3bb5 and now they are
fragmented to multiple areas each aligned to PMD boundary with gaps
between. The regression then seems to be caused mainly due to the
benchmark's memory access pattern suffering from TLB or cache aliasing due
to the aligned boundaries of the individual areas.
Another known regression bisected to commit
efa7df3e3bb5 is darktable [2]
[3] and early testing suggests this patch fixes the regression there as
well.
To fix the regression but still try to benefit from THP-friendly anonymous
mapping alignment, add a condition that the size of the mapping must be a
multiple of PMD size instead of at least PMD size. In case of many
odd-sized mapping like the cactusBSSN creates, those will stop being
aligned and with gaps between, and instead naturally merge again.

vmscan,migrate: fix page count imbalance on node stats when demoting pages
When numa balancing is enabled with demotion, vmscan will call
migrate_pages when shrinking LRUs. migrate_pages will decrement the
the node's isolated page count, leading to an imbalanced count when
invoked from (MG)LRU code.
The result is dmesg output like such:
$ cat /proc/sys/vm/stat_refresh
[77383.088417] vmstat_refresh: nr_isolated_anon -103212
[77383.088417] vmstat_refresh: nr_isolated_file -899642
This negative value may impact compaction and reclaim throttling.
The following path produces the decrement:
shrink_folio_list
demote_folio_list
migrate_pages
migrate_pages_batch
migrate_folio_move
migrate_folio_done
mod_node_page_state(-ve) <- decrement
This path happens for SUCCESSFUL migrations, not failures. Typically
callers to migrate_pages are required to handle putback/accounting for
failures, but this is already handled in the shrink code.
When accounting for migrations, instead do not decrement the count when
the migration reason is MR_DEMOTION. As of v6.11, this demotion logic
is the only source of MR_DEMOTION.

btrfs: fix defrag not merging contiguous extents due to merged extent maps
When running defrag (manual defrag) against a file that has extents that
are contiguous and we already have the respective extent maps loaded and
merged, we end up not defragging the range covered by those contiguous
extents. This happens when we have an extent map that was the result of
merging multiple extent maps for contiguous extents and the length of the
merged extent map is greater than or equals to the defrag threshold
length.
The script below reproduces this scenario:
$ cat test.sh
#!/bin/bash
DEV=/dev/sdi
MNT=/mnt/sdi
mkfs.btrfs -f $DEV
mount $DEV $MNT
# Create a 256K file with 4 extents of 64K each.
xfs_io -f -c "falloc 0 64K" \
-c "pwrite 0 64K" \
-c "falloc 64K 64K" \
-c "pwrite 64K 64K" \
-c "falloc 128K 64K" \
-c "pwrite 128K 64K" \
-c "falloc 192K 64K" \
-c "pwrite 192K 64K" \
$MNT/foo
umount $MNT
echo -n "Initial number of file extent items: "
btrfs inspect-internal dump-tree -t 5 $DEV | grep EXTENT_DATA | wc -l
mount $DEV $MNT
# Read the whole file in order to load and merge extent maps.
cat $MNT/foo > /dev/null
btrfs filesystem defragment -t 128K $MNT/foo
umount $MNT
echo -n "Number of file extent items after defrag with 128K threshold: "
btrfs inspect-internal dump-tree -t 5 $DEV | grep EXTENT_DATA | wc -l
mount $DEV $MNT
# Read the whole file in order to load and merge extent maps.
cat $MNT/foo > /dev/null
btrfs filesystem defragment -t 256K $MNT/foo
umount $MNT
echo -n "Number of file extent items after defrag with 256K threshold: "
btrfs inspect-internal dump-tree -t 5 $DEV | grep EXTENT_DATA | wc -l
Running it:
$ ./test.sh
Initial number of file extent items: 4
Number of file extent items after defrag with 128K threshold: 4
Number of file extent items after defrag with 256K threshold: 4
The 4 extents don't get merged because we have an extent map with a size
of 256K that is the result of merging the individual extent maps for each
of the four 64K extents and at defrag_lookup_extent() we have a value of
zero for the generation threshold ('newer_than' argument) since this is a
manual defrag. As a consequence we don't call defrag_get_extent() to get
an extent map representing a single file extent item in the inode's
subvolume tree, so we end up using the merged extent map at
defrag_collect_targets() and decide not to defrag.
Fix this by updating defrag_lookup_extent() to always discard extent maps
that were merged and call defrag_get_extent() regardless of the minimum
generation threshold ('newer_than' argument).
A test case for fstests will be sent along soon.

btrfs: fix extent map merging not happening for adjacent extents
If we have 3 or more adjacent extents in a file, that is, consecutive file
extent items pointing to adjacent extents, within a contiguous file range
and compatible flags, we end up not merging all the extents into a single
extent map.
For example:
$ mkfs.btrfs -f /dev/sdc
$ mount /dev/sdc /mnt/sdc
$ xfs_io -f -d -c "pwrite -b 64K 0 64K" \
-c "pwrite -b 64K 64K 64K" \
-c "pwrite -b 64K 128K 64K" \
-c "pwrite -b 64K 192K 64K" \
/mnt/sdc/foo
After all the ordered extents complete we unpin the extent maps and try
to merge them, but instead of getting a single extent map we get two
because:
1) When the first ordered extent completes (file range [0, 64K)) we
unpin its extent map and attempt to merge it with the extent map for
the range [64K, 128K), but we can't because that extent map is still
pinned;
2) When the second ordered extent completes (file range [64K, 128K)), we
unpin its extent map and merge it with the previous extent map, for
file range [0, 64K), but we can't merge with the next extent map, for
the file range [128K, 192K), because this one is still pinned.
The merged extent map for the file range [0, 128K) gets the flag
EXTENT_MAP_MERGED set;
3) When the third ordered extent completes (file range [128K, 192K)), we
unpin its extent map and attempt to merge it with the previous extent
map, for file range [0, 128K), but we can't because that extent map
has the flag EXTENT_MAP_MERGED set (mergeable_maps() returns false
due to different flags) while the extent map for the range [128K, 192K)
doesn't have that flag set.
We also can't merge it with the next extent map, for file range
[192K, 256K), because that one is still pinned.
At this moment we have 3 extent maps:
One for file range [0, 128K), with the flag EXTENT_MAP_MERGED set.
One for file range [128K, 192K).
One for file range [192K, 256K) which is still pinned;
4) When the fourth and final extent completes (file range [192K, 256K)),
we unpin its extent map and attempt to merge it with the previous
extent map, for file range [128K, 192K), which succeeds since none
of these extent maps have the EXTENT_MAP_MERGED flag set.
So we end up with 2 extent maps:
One for file range [0, 128K), with the flag EXTENT_MAP_MERGED set.
One for file range [128K, 256K), with the flag EXTENT_MAP_MERGED set.
Since after merging extent maps we don't attempt to merge again, that
is, merge the resulting extent map with the one that is now preceding
it (and the one following it), we end up with those two extent maps,
when we could have had a single extent map to represent the whole file.
Fix this by making mergeable_maps() ignore the EXTENT_MAP_MERGED flag.
While this doesn't present any functional issue, it prevents the merging
of extent maps which allows to save memory, and can make defrag not
merging extents too (that will be addressed in the next patch).

bpf, test_run: Fix LIVE_FRAME frame update after a page has been recycled
The test_run code detects whether a page has been modified and
re-initialises the xdp_frame structure if it has, using
xdp_update_frame_from_buff(). However, xdp_update_frame_from_buff()
doesn't touch frame->mem, so that wasn't correctly re-initialised, which
led to the pages from page_pool not being returned correctly. Syzbot
noticed this as a memory leak.
Fix this by also copying the frame->mem structure when re-initialising
the frame, like we do on initialisation of a new page from page_pool.
