3502596332 vdpa/mlx5: Fix suboptimal range on iotlb iteration
The starting iova address to iterate iotlb map entry within a range
was set to an irrelevant value when passing to the itree_next()
iterator, although luckily it doesn't affect the outcome of finding
out the granule of the smallest iotlb map size. Fix the code to make
it consistent with the following for-loop.

29ce8b8a4f vdpa/mlx5: Fix PA offset with unaligned starting iotlb map
When calculating the physical address range based on the iotlb and mr
[start,end) ranges, the offset of mr->start relative to map->start
is not taken into account. This leads to some incorrect and duplicate
mappings.

For the case when mr->start < map->start the code is already correct:
the range in [mr->start, map->start) was handled by a different
iteration.

83e445e64f vdpa/mlx5: Fix error path during device add
In the error recovery path of mlx5_vdpa_dev_add(), the cleanup is
executed and at the end put_device() is called which ends up calling
mlx5_vdpa_free(). This function will execute the same cleanup all over
again. Most resources support being cleaned up twice, but the recent
mlx5_vdpa_destroy_mr_resources() doesn't.

This change drops the explicit cleanup from within the
mlx5_vdpa_dev_add() and lets mlx5_vdpa_free() do its work.

This issue was discovered while trying to add 2 vdpa devices with the
same name:
$> vdpa dev add name vdpa-0 mgmtdev auxiliary/mlx5_core.sf.2
$> vdpa dev add name vdpa-0 mgmtdev auxiliary/mlx5_core.sf.3

... yields the following dump:

97ee04feb6 virtio_pci: Fix admin vq cleanup by using correct info pointer
vp_modern_avq_cleanup() and vp_del_vqs() clean up admin vq
resources by virtio_pci_vq_info pointer. The info pointer of admin
vq is stored in vp_dev->admin_vq.info instead of vp_dev->vqs[].
Using the info pointer from vp_dev->vqs[] for admin vq causes a
kernel NULL pointer dereference bug.
In vp_modern_avq_cleanup() and vp_del_vqs(), get the info pointer
from vp_dev->admin_vq.info for admin vq to clean up the resources.
Also make info ptr as argument of vp_del_vq() to be symmetric with
vp_setup_vq().

vp_reset calls vp_modern_avq_cleanup, and causes the Call Trace:

0b364cf53b vdpa: solidrun: Fix UB bug with devres
In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to
pcim_iomap_regions() is placed on the stack. Neither
pcim_iomap_regions() nor the functions it calls copy that string.

Should the string later ever be used, this, consequently, causes
undefined behavior since the stack frame will by then have disappeared.

Fix the bug by allocating the strings on the heap through
devm_kasprintf().

1d4832becd 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()
whenever we clear the young bits on PMDs/PTEs.

ddd6d8e975 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.

[1]: https://lore.kernel.org/linux-mm/20240926013506.860253-18-jthoughton@google.com/


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.

33e83ffe4c A few scheduler fixes:
- 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.

   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.

68f05b251b A single fix for perf:
perf_event_clear_cpumask() uses list_for_each_entry_rcu() without being
   in a RCU read side critical section, which triggers a "suspicious RCU
   usage" warning.
 
   It turns out that the list walk does not be RCU protected because the
   write side lock is held in this contxt.
 
   Change it to a regular list walk.

77dc55a978 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,*2,*k*r*8,*a*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*r*a*0,*1,*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*r*a*0,*1,*18,*1C,*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*3,*k*r*a*8,*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*1,*k*120,*r*a*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*1,*k*130,*r*a*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*3,*k*r*a*2,*22,*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*28,*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*26,*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*");
  MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*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 e0e9263271 ("[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.

2e766a1f5f 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
do not match.

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
(or vice versa), the output is incorrect:

  $ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
  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.

071b24b54d Input: fix regression when re-registering input handlers
Commit d469647baf ("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.

Merge tag 'cxl-fixes-6.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull cxl fixes from Ira Weiny:
 "The bulk of these fixes center around an initialization order bug
  reported by Gregory Price and some additional fall out from the
  debugging effort.

  In summary, cxl_acpi and cxl_mem race and previously worked because of
  a bus_rescan_devices() while testing without modules built in.

  Unfortunately with modules built in the rescan would fail due to the
  cxl_port driver being registered late via the build order. Furthermore
  it was found bus_rescan_devices() did not guarantee a probe barrier
  which CXL was expecting. Additional fixes to cxl-test and decoder
  allocation came along as they were found in this debugging effort.

  The other fixes are pretty minor but one affects trace point data seen
  by user space.

  Summary:

   - Fix crashes when running with cxl-test code

   - Fix Trace DRAM Event Record field decodes

   - Fix module/built in initialization order errors

   - Fix use after free on decoder shutdowns

   - Fix out of order decoder allocations

   - Improve cxl-test to better reflect real world systems"

a031e15404 RISC-V Fixes for 6.11-rc6
* A fix that avoids accessing the early boot ACPI tables via unsafe
   memory attributes, which can result in incorrect ACPI table data
   appearing.  This can cause all sorts of bad behavior.
 * A fix to avoid compiler-insert library calls in the VDSO.
 * GCC+Rust builds have been disabled, to avoid issues related to ISA
   string mismatched between the GCC and LLVM Rust implementations.
 * The NX flag is now set in the EFI PE/COFF headers, which is necessary
   for some distro GRUB versions to boot images.
 * A fix to avoid leaking DT node reference counts on ACPI systems during
   cache info parsing.
 * CPU numbers are now printed as unsigned values during hotplug.
 * A pair of build fixes for usused macros, which can trigger warnings on
   some configurations.

 - Avoid accessing the early boot ACPI tables via unsafe memory
   attributes, which can result in incorrect ACPI table data appearing.
   This can cause all sorts of bad behavior.

 - Avoid compiler-inserted library calls in the VDSO.

 - GCC+Rust builds have been disabled, to avoid issues related to ISA
   string mismatched between the GCC and LLVM Rust implementations.

 - The NX flag is now set in the EFI PE/COFF headers, which is necessary
   for some distro GRUB versions to boot images.

 - A fix to avoid leaking DT node reference counts on ACPI systems
   during cache info parsing.

 - CPU numbers are now printed as unsigned values during hotplug.

 - A pair of build fixes for usused macros, which can trigger warnings
   on some configurations.

d4148aeab4 mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes
Since commit efa7df3e3b ("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 efa7df3e3b 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 efa7df3e3b 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.

35e41024c4 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.
