Do a bit of readability spring cleaning:
- Fix misaligned structure member in perf_addr_filter: the new
struct perf_addr_filter::action member was too long, but when
it was added it was not aligned properly. Align all fields to
the customary column 41 alignment of most of the rest of the
header.
- Adjust the vertical alignment of the definition of other
structures and definitions as well, so that the 'most of' in
the previous paragraph changes to 'all of'. ;-)
- Prettify the assignments in perf_clear_branch_entry_bitfields()
- Move comments from CPP definitions to outside the macro
- Move perf_guest_info_callbacks and related defines from the front
of the header closer to where it's used within the header.
- And more #endif markers for larger CPP blocks and standardize
#if/#else/#endif blocks to the following nomenclature:
#ifdef CONFIG_FOO
...
#else /* !CONFIG_FOO: */
...
#endif /* !CONFIG_FOO */
- Standardize on consistently using the 'extern' storage class where
appropriate, we had cases where method prototypes sometimes omitted
the storage class:
extern void perf_pmu_migrate_context(struct pmu *pmu,
int src_cpu, int dst_cpu);
int perf_event_read_local(struct perf_event *event, u64 *value,
u64 *enabled, u64 *running);
extern u64 perf_event_read_value(struct perf_event *event,
u64 *enabled, u64 *running);
Which is obviously a bit confusing and adds unnecessary noise.
- s/__u64/u64 and similar cleanups: there's no point in using __u64
in non-UAPI headers, and doing so only adds unnecessary visual noise.
- Harmonize all multi-parameter function prototypes along the following
style:
extern struct perf_event *
perf_event_create_kernel_counter(struct perf_event_attr *attr,
int cpu,
struct task_struct *task,
perf_overflow_handler_t callback,
void *context);
- etc.

Memory sparing is defined as a repair function that replaces a portion of
memory with a portion of functional memory at that same DPA. The subclasses
for this operation vary in terms of the scope of the sparing being
performed. The cacheline sparing subclass refers to a sparing action that
can replace a full cacheline. Row sparing is provided as an alternative to
PPR sparing functions and its scope is that of a single DDR row.
As per CXL r3.2 Table 8-125 foot note 1. Memory sparing is preferred over
PPR when possible.
Bank sparing allows an entire bank to be replaced. Rank sparing is defined
as an operation in which an entire DDR rank is replaced.
Memory sparing maintenance operations may be supported by CXL devices
that implement CXL.mem protocol. A sparing maintenance operation requests
the CXL device to perform a repair operation on its media.
For example, a CXL device with DRAM components that support memory sparing
features may implement sparing maintenance operations.
The host may issue a query command by setting query resources flag in the
input payload (CXL spec 3.2 Table 8-120) to determine availability of
sparing resources for a given address. In response to a query request,
the device shall report the resource availability by producing the memory
sparing event record (CXL spec 3.2 Table 8-60) in which the Channel, Rank,
Nibble Mask, Bank Group, Bank, Row, Column, Sub-Channel fields are a copy
of the values specified in the request.
During the execution of a sparing maintenance operation, a CXL memory
device:
- may not retain data
- may not be able to process CXL.mem requests correctly.
These CXL memory device capabilities are specified by restriction flags
in the memory sparing feature readable attributes.
When a CXL device identifies error on a memory component, the device
may inform the host about the need for a memory sparing maintenance
operation by using DRAM event record, where the 'maintenance needed' flag
may set. The event record contains some of the DPA, Channel, Rank,
Nibble Mask, Bank Group, Bank, Row, Column, Sub-Channel fields that
should be repaired. The userspace tool requests for maintenance operation
if the 'maintenance needed' flag set in the CXL DRAM error record.
CXL spec 3.2 section 8.2.10.7.1.4 describes the device's memory sparing
maintenance operation feature.
CXL spec 3.2 section 8.2.10.7.2.3 describes the memory sparing feature
discovery and configuration.
Add support for controlling CXL memory device memory sparing feature.
Register with EDAC driver, which gets the memory repair attr descriptors
from the EDAC memory repair driver and exposes sysfs repair control
attributes for memory sparing to the userspace. For example CXL memory
sparing control for the CXL mem0 device is exposed in
/sys/bus/edac/devices/cxl_mem0/mem_repairX/
Use case
========
1. CXL device identifies a failure in a memory component, report to
userspace in a CXL DRAM trace event with DPA and other attributes of
memory to repair such as channel, rank, nibble mask, bank Group,
bank, row, column, sub-channel.
2. Rasdaemon process the trace event and may issue query request in sysfs
check resources available for memory sparing if either of the following
conditions met.
- 'maintenance needed' flag set in the event record.
- 'threshold event' flag set for CVME threshold feature.
- When the number of corrected error reported on a CXL.mem media to the
userspace exceeds the threshold value for corrected error count defined
by the userspace policy.
3. Rasdaemon process the memory sparing trace event and issue repair
request for memory sparing.
Kernel CXL driver shall report memory sparing event record to the userspace
with the resource availability in order rasdaemon to process the event
record and issue a repair request in sysfs for the memory sparing operation
in the CXL device.
Note: Based on the feedbacks from the community 'query' sysfs attribute is
removed and reporting memory sparing error record to the userspace are not
supported. Instead userspace issues sparing operation and kernel does the
same to the CXL memory device, when 'maintenance needed' flag set in the
DRAM event record.
Add checks to ensure the memory to be repaired is offline and if online,
then originates from a CXL DRAM error record reported in the current boot
before requesting a memory sparing operation on the device.
Note: Tested memory sparing feature control with QEMU patch

Using acpi_irq_create_hierarchy() in the cases where the code
also handles OF leads to code duplication as the ACPI subsystem
doesn't provide means to compute the IRQ domain parent whereas
the OF does.
Introduce acpi_get_gsi_dispatcher() so that the drivers relying
on both ACPI and OF may use irq_domain_create_hierarchy() in the
common code paths.

The KVM/arm64 uses SMCCC to detect hypervisor presence. That code is
private, and it follows the SMCCC specification. Other existing and
emerging hypervisor guest implementations can and should use that
standard approach as well.
Factor out a common infrastructure that the guests can use, update KVM
to employ the new API. The central notion of the SMCCC method is the
UUID of the hypervisor, and the new API follows that.
No functional changes. Validated with a KVM/arm64 guest.

In prior kernel versions (5.8-6.8), commit 9f6c61f96f2d9 ("proc/mounts:
add cursor") introduced MNT_CURSOR, a flag used by readers from
/proc/mounts to keep their place while reading the file. Later, commit
2eea9ce4310d8 ("mounts: keep list of mounts in an rbtree") removed this
flag and its value has since been repurposed.
For debuggers iterating over the list of mounts, cursors should be
skipped as they are irrelevant. Detecting whether an element is a cursor
can be difficult. Since the MNT_CURSOR flag is a preprocessor constant,
it's not present in debuginfo, and since its value is repurposed, we
cannot hard-code it. For this specific issue, cursors are possible to
detect in other ways, but ideally, we would be able to read the mount
flag definitions out of the debuginfo. For that reason, convert the
mount flags to an enum.

Supporting a 1:n relationship between nft_hook and nf_hook_ops is
convenient since a chain's or flowtable's nft_hooks may remain in place
despite matching interfaces disappearing. This stabilizes ruleset dumps
in that regard and opens the possibility to claim newly added interfaces
which match the spec. Also it prepares for wildcard interface specs
since these will potentially match multiple interfaces.
All spots dealing with hook registration are updated to handle a list of
multiple nf_hook_ops, but nft_netdev_hook_alloc() only adds a single
item for now to retain the old behaviour. The only expected functional
change here is how vanishing interfaces are handled: Instead of dropping
the respective nft_hook, only the matching nf_hook_ops are dropped.
To safely remove individual ops from the list in netdev handlers, an
rcu_head is added to struct nf_hook_ops so kfree_rcu() may be used.
There is at least nft_flowtable_find_dev() which may be iterating
through the list at the same time.

While nf_conntrack_id() doesn't need any functionaliy from conntrack, it
does reside in nf_conntrack_core.c -- callers add a module
dependency on conntrack.
Followup patch will need to compute the conntrack id from nf_tables_trace.c
to include it in nf_trace messages emitted to userspace via netlink.
I don't want to introduce a module dependency between nf_tables and
conntrack for this.
Since trace is slowpath, the added indirection is ok.
One alternative is to move nf_conntrack_id to the netfilter/core.c,
but I don't see a compelling reason so far.

nf_skb_duplicated is a per-CPU variable and relies on disabled BH for its

this data structure requires explicit locking.
Due to the recursion involved, the simplest change is to make it a

in_nf_duplicate. Add it to the existing bitfield so it doesn't use

As explained in the next patch, SO_PASSRIGHTS would have a problem
if we assigned a corresponding bit to socket->flags, so it must be
managed in struct sock.
Mixing socket->flags and sk->sk_flags for similar options will look
confusing, and sk->sk_flags does not have enough space on 32bit system.
Also, as mentioned in commit 16e572626961 ("af_unix: dont send
SCM_CREDENTIALS by default"), SOCK_PASSCRED and SOCK_PASSPID handling
is known to be slow, and managing the flags in struct socket cannot
avoid that for embryo sockets.
Let's move SOCK_PASS{CRED,PIDFD,SEC} to struct sock.
While at it, other SOCK_XXX flags in net.h are grouped as enum.
Note that assign_bit() was atomic, so the writer side is moved down
after lock_sock() in setsockopt(), but the bit is only read once
in sendmsg() and recvmsg(), so lock_sock() is not needed there.

On cifs, "DIO reads" (specified by O_DIRECT) need to be differentiated from
"unbuffered reads" (specified by cache=none in the mount parameters). The
difference is flagged in the protocol and the server may behave
differently: Windows Server will, for example, mandate that DIO reads are
block aligned.
Fix this by adding a NETFS_UNBUFFERED_READ to differentiate this from
NETFS_DIO_READ, parallelling the write differentiation that already exists.
cifs will then do the right thing.

into THP in the background. However, now not only tmpfs/shmem can support
large folios, but some other file systems (such as XFS, erofs ...) also
support large folios. Therefore, it is time to decouple the support of
file folios collapse from SHMEM.

The "try_" prefix is confusing, since it made people believe that
try_alloc_pages() is analogous to spin_trylock() and NULL return means
EAGAIN. This is not the case. If it returns NULL there is no reason to
call it again. It will most likely return NULL again. Hence rename it to
alloc_pages_nolock() to make it symmetrical to free_pages_nolock() and
document that NULL means ENOMEM.

Having encountered a trinity report in linux-next (Linked in the 'Closes'
tag) it appears that there are legitimate situations where a file-backed
mapping can be acquired but no file->f_op->mmap or
file->f_op->mmap_prepare is set, at which point do_mmap() should simply
error out with -ENODEV.
Since previously we did not warn in this scenario and it appears we rely
upon this, restore this situation, while retaining a WARN_ON_ONCE() for
the case where both are set, which is absolutely incorrect and must be
addressed and thus always requires a warning.
If further work is required to chase down precisely what is causing this,
then we can later restore this, but it makes no sense to hold up this
series to do so, as this is existing and apparently expected behaviour.

In do_set_pmd(), we always use the folio->page to build PMD mappings for
the entire folio. Since all callers of do_set_pmd() already hold a stable
folio, converting do_set_pmd() to take a folio is safe and more
straightforward.
In addition, to ensure the extensibility of do_set_pmd() for supporting
larger folios beyond PMD size, we keep the 'page' parameter to specify
which page within the folio should be mapped.
No functional changes expected.

We've already gotten the stable locked folio in collapse_pte_mapped_thp(),
so just use folio for set_huge_pmd() to set the PMD entry, which is more
straightforward.
Moreover, we will check the folio size in do_set_pmd(), so we can remove
the unnecessary VM_BUG_ON() in set_huge_pmd(). While we are at it, we can
also remove the PageTransHuge(), as it currently has no callers.

Let's use our new interface. In remap_pfn_range(), we'll now decide
whether we have to track (full VMA covered) or only lookup the cachemode
(partial VMA covered).
Remember what we have to untrack by linking it from the VMA. When
duplicating VMAs (e.g., splitting, mremap, fork), we'll handle it similar
to anon VMA names, and use a kref to share the tracking.
Once the last VMA un-refs our tracking data, we'll do the untracking,
which simplifies things a lot and should sort our various issues we saw
recently, for example, when partially unmapping/zapping a tracked VMA.
This change implies that we'll keep tracking the original PFN range even
after splitting + partially unmapping it: not too bad, because it was not
working reliably before. The only thing that kind-of worked before was
shrinking such a mapping using mremap(): we managed to adjust the
reservation in a hacky way, now we won't adjust the reservation but leave
it around until all involved VMAs are gone.
If that ever turns out to be an issue, we could hook into VM splitting
code and split the tracking; however, that adds complexity that might not
be required, so we'll keep it simple for now.

acpi_parse_cfmws() currently adds empty CFMWS ranges to numa_meminfo with
the expectation that numa_cleanup_meminfo moves them to
numa_reserved_meminfo. There is no need for that indirection when it is
known in advance that these unpopulated ranges are meant for
numa_reserved_meminfo in support of future hotplug / CXL provisioning.
Introduce and use numa_add_reserved_memblk() to add the empty CFMWS ranges
directly.

Other subsystems may make use of the cgroup hierarchy with the cgroup_bpf
support being one such example. For such a feature, it's useful to be able
to hook into cgroup creation and destruction paths to perform
feature-specific initializations and cleanups.
Add cgroup_lifetime_notifier which generates CGROUP_LIFETIME_ONLINE and
CGROUP_LIFETIME_OFFLINE events whenever cgroups are created and destroyed,
respectively.
The next patch will convert cgroup_bpf to use the new notifier and other

ASoC: Updates for v6.16
The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.
- Conversion of quite a few drivers to newer GPIO APIs.
- More helpers and cleanups from Mormimoto-san.
- Support for a wider range of AVS platforms.
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32,
Everest Semiconductor ES8389, Longsoon-1 AC'97 controllers, nVidia
Tegra264, Richtek ALC203 and RT9123 and Rockchip SAI controllers.
