The UEFI specification does not make any mention of a maximum variable
name size, so the headers and implementation shouldn't claim that one
exists either.
Comments referring to this limit have been removed or rewritten, as this
is an implementation detail local to the Linux kernel.
Where appropriate, the magic value of 1024 has been replaced with
EFI_VAR_NAME_LEN, as this is used for the efi_variable struct
definition. This in itself does not change any behavior, but should
serve as points of interest when making future changes in the same area.
A related build-time check has been added to ensure that the special
512 byte sized buffer will not overflow with a potentially decreased
EFI_VAR_NAME_LEN.

The soft lockup detector lacks a mechanism to identify interrupt storms as
root cause of a lockup. To enable this the detector needs a mechanism to
snapshot the interrupt count statistics on a CPU when the detector observes
a potential lockup scenario and compare that against the interrupt count
when it warns about the lockup later on. The number of interrupts in that
period give a hint whether the lockup might have been caused by an interrupt
storm.
Instead of having extra storage in the lockup detector and accessing the
internals of the interrupt descriptor directly, add a snapshot member to
the per CPU irq_desc::kstat_irq structure and provide interfaces to take a
snapshot of all interrupts on the current CPU and to retrieve the delta of
a specific interrupt later on.

The irq_desc::kstat_irqs member is a per-CPU variable of type int, which is
only capable of counting. A snapshot mechanism for interrupt statistics
will be added soon, which requires an additional variable to store the
snapshot.
To facilitate expansion, convert kstat_irqs here to a struct containing
only the count.

Add support for ACPI RAS2 feature table(RAS2) defined in the ACPI 6.5
Specification & upwards revision, section 5.2.21.
The RAS2 table provides interfaces for platform RAS features. RAS2 offers
the same services as RASF, but is more scalable than the latter.
RAS2 supports independent RAS controls and capabilities for a given RAS
feature for multiple instances of the same component in a given system.
The platform can support either RAS2 or RASF but not both.

The following patchset contains Netfilter fixes for net:
Patches #1 and #2 add missing rcu read side lock when iterating over
expression and object type list which could race with module removal.
Patch #3 prevents promisc packet from visiting the bridge/input hook
to amend a recent fix to address conntrack confirmation race
in br_netfilter and nf_conntrack_bridge.
Patch #4 adds and uses iterate decorator type to fetch the current
pipapo set backend datastructure view when netlink dumps the
set elements.
Patch #5 fixes removal of duplicate elements in the pipapo set backend.
Patch #6 flowtable validates pppoe header before accessing it.
Patch #7 fixes flowtable datapath for pppoe packets, otherwise lookup
fails and pppoe packets follow classic path.

Hi all,
this series converts the SCSI midlayer and LLDDs to use atomic queue
limits API. It is pretty straight forward, except for the mpt3mr
driver which does really weird and probably already broken things by
setting limits from unlocked device iteration callbacks.
I will probably defer the (more complicated) ULD changes to the next
merge window as they would heavily conflict with Damien's zone write
plugging series. With that the series could go in through the SCSI
tree if Jens' ACKs the core block layer bits.

Existing remove_dev_pasid() callbacks of the underlying iommu drivers
get the attached domain from the group->pasid_array. However, the domain
stored in group->pasid_array is not always correct in all scenarios.
A wrong domain may result in failure in remove_dev_pasid() callback.
To avoid such problems, it is more reliable to pass the domain to the
remove_dev_pasid() op.

After commit dfa2f0483360 ("tcp: get rid of sysctl_tcp_adv_win_scale"),
we noticed an application-level timeout due to reduced throughput.
Before the commit, for a client that sets SO_RCVBUF to 65k, it takes
around 22 seconds to transfer 10M data. After the commit, it takes 40
seconds. Because our application has a 30-second timeout, this
regression broke the application.
The reason that it takes longer to transfer data is that
tp->scaling_ratio is initialized to a value that results in ~0.25 of
rcvbuf. In our case, SO_RCVBUF is set to 65536 by the application, which
translates to 2 * 65536 = 131,072 bytes in rcvbuf and hence a ~28k
initial receive window.
Later, even though the scaling_ratio is updated to a more accurate
skb->len/skb->truesize, which is ~0.66 in our environment, the window
stays at ~0.25 * rcvbuf. This is because tp->window_clamp does not
change together with the tp->scaling_ratio update when autotuning is
disabled due to SO_RCVBUF. As a result, the window size is capped at the
initial window_clamp, which is also ~0.25 * rcvbuf, and never grows
bigger.
Most modern applications let the kernel do autotuning, and benefit from
the increased scaling_ratio. But there are applications such as kafka
that has a default setting of SO_RCVBUF=64k.
This patch increases the initial scaling_ratio from ~25% to 50% in order
to make it backward compatible with the original default
sysctl_tcp_adv_win_scale for applications setting SO_RCVBUF.

To ultimately allow BPF programs attached to perf events to completely
suppress all of the effects of a perf event overflow (rather than just the
sample output, as they do today), call bpf_overflow_handler() from
__perf_event_overflow() directly rather than modifying struct perf_event's
overflow_handler. Return the BPF program's return value from
bpf_overflow_handler() so that __perf_event_overflow() knows how to
proceed. Remove the now unnecessary orig_overflow_handler from struct
perf_event.
This patch is solely a refactoring and results in no behavior change.

Add a DEFINE_FREE() clause for x509_certificate structs and use it in
x509_cert_parse() and x509_key_preparse(). These are the only functions
where scope-based x509_certificate allocation currently makes sense.
A third user will be introduced with the forthcoming SPDM library
(Security Protocol and Data Model) for PCI device authentication.
Unlike most other DEFINE_FREE() clauses, this one checks for IS_ERR()
instead of NULL before calling x509_free_certificate() at end of scope.
That's because the "constructor" of x509_certificate structs,
x509_cert_parse(), returns a valid pointer or an ERR_PTR(), but never
NULL.
Comparing the Assembler output before/after has shown they are identical,
save for the fact that gcc-12 always generates two return paths when
__cleanup() is used, one for the success case and one for the error case.
In x509_cert_parse(), add a hint for the compiler that kzalloc() never
returns an ERR_PTR(). Otherwise the compiler adds a gratuitous IS_ERR()
check on return. Introduce an assume() macro for this which can be
re-used elsewhere in the kernel to provide hints for the compiler.

For NIST P192/256/384 the public key's x and y parameters could be copied
directly from a given array since both parameters filled 'ndigits' of
digits (a 'digit' is a u64). For support of NIST P521 the key parameters
need to have leading zeros prepended to the most significant digit since
only 2 bytes of the most significant digit are provided.
Therefore, implement ecc_digits_from_bytes to convert a byte array into an
array of digits and use this function in ecdsa_set_pub_key where an input
byte array needs to be converted into digits.

RTO_ONLINK was a flag used in ->flowi4_tos that allowed to alter the
scope of an IPv4 route lookup. Setting this flag was equivalent to
specifying RT_SCOPE_LINK in ->flowi4_scope.
With commit ec20b2830093 ("ipv4: Set scope explicitly in
ip_route_output()."), the last users of RTO_ONLINK have been removed.
Therefore, we can now drop the code that checked this bit and stop
modifying ->flowi4_scope in ip_route_output_key_hash().

Refactor some of the skb frag ref/unref helpers for improved clarity.
Implement napi_pp_get_page() to be the mirror counterpart of
napi_pp_put_page().
Implement skb_page_ref() to be the mirror of skb_page_unref().
Improve __skb_frag_ref() to become a mirror counterpart of
__skb_frag_unref(). Previously unref could handle pp & non-pp pages,
while the ref could only handle non-pp pages. Now both the ref & unref
helpers can correctly handle both pp & non-pp pages.
Now that __skb_frag_ref() can handle both pp & non-pp pages, remove
skb_pp_frag_ref(), and use __skb_frag_ref() instead. This lets us
remove pp specific handling from skb_try_coalesce.
Additionally, since __skb_frag_ref() can now handle both pp & non-pp
pages, a latent issue in skb_shift() should now be fixed. Previously
this function would do a non-pp ref & pp unref on potential pp frags
(fragfrom). After this patch, skb_shift() should correctly do a pp
ref/unref on pp frags.

Add a new header, linux/skbuff_ref.h, which contains all the skb_*_ref()
helpers. Many of the consumers of skbuff.h do not actually use any of
the skb ref helpers, and we can speed up compilation a bit by minimizing
this header file.
Additionally in the later patch in the series we add page_pool support
to skb_frag_ref(), which requires some page_pool dependencies. We can
now add these dependencies to skbuff_ref.h instead of a very ubiquitous
skbuff.h

UFS spec version 2.1 was published more than 10 years ago. It is
vanishingly unlikely that even there are out there platforms that uses
earlier host controllers, let alone that those ancient platforms will ever
run a V6.10 kernel. To be extra cautious, leave out removal of UFSHCI 2.0
support from this patch, and just remove support of host controllers prior
to UFS2.0.
This patch removes some legacy tuning calls that no longer apply.

This is a version of ->slave_configure that also takes a queue_limits
structure that the caller applies, and thus allows drivers to reconfigure
the queue using the atomic queue limits API.
In the long run it should also replace ->slave_configure entirely as there
is no need to have two different methods here, and the slave name in
addition to being politically charged also has no basis in the SCSI
standards or the kernel code.

While we really should be killing the block layer bounce buffering ASAP, I
even more urgently need to stop the drivers to fiddle with the limits from
->slave_configure. Add a no_highmem flag to the Scsi_Host to centralize
this setting and switch the remaining four drivers that use block layer
bounce buffering to it.

having it set a queue limits after creating the BSG queues, add a field so
