Lockdep considers this an AA deadlock because the different resize_lock
mutexes reside in the same lockdep class, but this is a false positive.
Place them in distinct classes to avoid these warnings.

pgalloc_tag_sub() might call page_ext_put() using a page different from
the one used in page_ext_get() call. This does not pose an issue since
page_ext_put() ignores this parameter as long as it's non-NULL but
technically this is wrong. Fix it by storing the original page used in
page_ext_get() and passing it to page_ext_put().

This mostly reverts commit af3b854492f3 ("mm/page_alloc.c: allow error
injection"). The commit made should_fail_alloc_page() a noinline function
that's always called from the page allocation hotpath, even if it's empty
because CONFIG_FAIL_PAGE_ALLOC is not enabled, and there is no option to
disable it and prevent the associated function call overhead.
As with the preceding patch "mm, slab: put should_failslab back behind
CONFIG_SHOULD_FAILSLAB" and for the same reasons, put the
should_fail_alloc_page() back behind the config option. When enabled, the
ALLOW_ERROR_INJECTION and BTF_ID records are preserved so it's not a
complete revert.

Patch series "revert unconditional slab and page allocator fault injection
calls".
These two patches largely revert commits that added function call overhead
into slab and page allocation hotpaths and that cannot be currently
disabled even though related CONFIG_ options do exist.
A much more involved solution that can keep the callsites always existing
but hidden behind a static key if unused, is possible [1] and can be
pursued by anyone who believes it's necessary. Meanwhile the fact the
should_failslab() error injection is already not functional on kernels
built with current gcc without anyone noticing [2], and lukewarm response
to [1] suggests the need is not there. I believe it will be more fair to
have the state after this series as a baseline for possible further
optimisation, instead of the unconditional overhead.
For example a possible compromise for anyone who's fine with an empty
function call overhead but not the full CONFIG_FAILSLAB /
CONFIG_FAIL_PAGE_ALLOC overhead is to reuse patch 1 from [1] but insert a
static key check only inside should_failslab() and
should_fail_alloc_page() before performing the more expensive checks.
[1] https://lore.kernel.org/all/20240620-fault-injection-statickeys-v2-0-e23947d3d84b@suse.cz/#t
[2] https://github.com/bpftrace/bpftrace/issues/3258
This patch (of 2):
This mostly reverts commit 4f6923fbb352 ("mm: make should_failslab always
available for fault injection"). The commit made should_failslab() a
noinline function that's always called from the slab allocation hotpath,
even if it's empty because CONFIG_SHOULD_FAILSLAB is not enabled, and
there is no option to disable that call. This is visible in profiles and
the function call overhead can be noticeable especially with cpu
mitigations.
Meanwhile the bpftrace program example in the commit silently does not
work without CONFIG_SHOULD_FAILSLAB anyway with a recent gcc, because the
empty function gets a .constprop clone that is actually being called
(uselessly) from the slab hotpath, while the error injection is hooked to
the original function that's not being called at all [1].
Thus put the whole should_failslab() function back behind
CONFIG_SHOULD_FAILSLAB. It's not a complete revert of 4f6923fbb352 - the
int return type that returns -ENOMEM on failure is preserved, as well
ALLOW_ERROR_INJECTION annotation. The BTF_ID() record that was meanwhile
added is also guarded by CONFIG_SHOULD_FAILSLAB.

Pull ata updates from Niklas Cassel:
- ATA PASS-THROUGH sense data cleanups and fixes (Igor Pylypiv)
Store the sense data for ATA PASS-THROUGH commands at the correct
offset in the sense buffer when using fixed format sense data.
Cleanup the logic related to generating sense data for PASS-THROUGH
commands. Generating sense data for PASS-THROUGH commands would
overwrite any eventual (real) sense data received from the device.
Honor the D_SENSE bit when generating sense data for PASS-THROUGH
commands. (The D_SENSE bit can be set by the user, and determines if
the returned sense data should be in fixed format or descriptor
format)
- ata port allocation cleanups (me)
Assign the ata port print_id at port allocation time, such that the
ata_port_* print functions can be used earlier in the init call
chain.
Change the ata port port print_id to use ida_alloc(), such that
print_ids will get reused on rmmod + modprobe, instead of being
incremented indefinitely.
Remove wrappers that only existed in order to export the internal
libata functions which they wrapped, and instead export the libata
functions directly.
- Update SATA_MOBILE_LPM_POLICY Kconfig default to med_power_with_dipm
(Mario Limonciello)
Using this default was not always a good idea before, because it
would break hot plug support. However, with LPM changes in recent
kernels, a port marked as external will not enable LPM (in order to
not break hot plug), so it is now safe to change the default value of
this Kconfig.
All major Linux distros have had SATA_MOBILE_LPM_POLICY set to
med_power_with_dipm for quite a long time

Pull nfsd updates from Chuck Lever:
"This is a light release containing optimizations, code clean-ups, and
minor bug fixes.
This development cycle focused on work outside of upstream kernel
development:
- Continuing to build upstream CI for NFSD based on kdevops
- Continuing to focus on the quality of NFSD in LTS kernels
- Participation in IETF nfsv4 WG discussions about NFSv4 ACLs,
directory delegation, and NFSv4.2 COPY offload
Notable features for v6.11 that do not come through the NFSD tree
include NFS server-side support for the new pNFS NVMe layout type
[RFC9561]. Functional testing for pNFS block layouts like this one has
been introduced to our kdevops CI harness. Work on improving the
resolution of file attribute time stamps in local filesystems is also
ongoing tree-wide.
As always I am grateful to NFSD contributors, reviewers, testers, and
bug reporters who participated during this cycle"

Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.
Core & protocols:
- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT
- Use flex array for netdevice priv area, ensure its cache alignment
- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful
- Support scheduling transmission of packets based on CLOCK_TAI
- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets
- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address
- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync
- Improve TCP compliance with RFC 9293 for simultaneous connect()
- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it
- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled
- Introduce IPPROTO_SMC for selecting SMC when socket is created
- Allow UDP GSO transmit from devices with no checksum offload
- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding
- nf_tables: shrink memory consumption for transaction objects
Things we sprinkled into general kernel code:
- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]
- Add IRQ information in sysfs for auxiliary bus
- Introduce guard definition for local_lock
- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures
BPF:
- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered
- Add new kfuncs for a generic, open-coded bits iterator
- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head
- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules
- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs
- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter
- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs
Driver API:
- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose
- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits
- Track additional RSS contexts in the core, make sure configuration
changes don't break them
- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths
- Support updating firmware on SFP modules
Tests and tooling:
- mptcp: use net/lib.sh to manage netns

Pull sysctl updates from Joel Granados:
- Remove "->procname == NULL" check when iterating through sysctl table
arrays
Removing sentinels in ctl_table arrays reduces the build time size
and runtime memory consumed by ~64 bytes per array. With all
ctl_table sentinels gone, the additional check for ->procname == NULL
that worked in tandem with the ARRAY_SIZE to calculate the size of
the ctl_table arrays is no longer needed and has been removed. The
sysctl register functions now returns an error if a sentinel is used.
- Preparation patches for sysctl constification
Constifying ctl_table structs prevents the modification of
proc_handler function pointers as they would reside in .rodata. The
ctl_table arguments in sysctl utility functions are const qualified
in preparation for a future treewide proc_handler argument
constification commit.
- Misc fixes
Increase robustness of set_ownership by providing sane default
ownership values in case the callee doesn't set them. Bound check
proc_dou8vec_minmax to avoid loading buggy modules and give sysctl
testing module a name to avoid compiler complaints.

Pull EFI updates from Ard Biesheuvel:
"Note the removal of the EFI fake memory map support - this is believed
to be unused and no longer worth supporting. However, we could easily
bring it back if needed.
With recent developments regarding confidential VMs and unaccepted
memory, combined with kexec, creating a known inaccurate view of the
firmware's memory map and handing it to the OS is a feature we can
live without, hence the removal. Alternatively, I could imagine making
this feature mutually exclusive with those confidential VM related
features, but let's try simply removing it first.
Summary:
- Drop support for the 'fake' EFI memory map on x86
- Add an SMBIOS based tweak to the EFI stub instructing the firmware
on x86 Macbook Pros to keep both GPUs enabled
- Replace 0-sized array with flexible array in EFI memory attributes

KVM generic changes for 6.11
- Enable halt poll shrinking by default, as Intel found it to be a clear win.
- Setup empty IRQ routing when creating a VM to avoid having to synchronize
SRCU when creating a split IRQCHIP on x86.
- Rework the sched_in/out() paths to replace kvm_arch_sched_in() with a flag
that arch code can use for hooking both sched_in() and sched_out().
- Take the vCPU @id as an "unsigned long" instead of "u32" to avoid
truncating a bogus value from userspace, e.g. to help userspace detect bugs.
- Mark a vCPU as preempted if and only if it's scheduled out while in the
KVM_RUN loop, e.g. to avoid marking it preempted and thus writing guest
memory when retrieving guest state during live migration blackout.
- A few minor cleanups

Pull spi updates from Mark Brown:
"There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
Summary:
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper
and allowing the DMA mapping decision to be done per transfer
instead of per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A"

Pull regulator updates from Mark Brown:
"This s a very quiet release for the regulator API, we have a few new
devices (most of which are just ID updates) and one new fairly
specialist core feature for use in interrupt context.
- An API allowing lockless enable/disable for regulators acquired in
exclusive mode, for use in interrupt contexts
- A rewrite of the MedaTek DVFSRC regulator driver which apparently
never worked
- Support for Mediaktek MT6312, Qualcomm QCA6390 and WCN7850, Renesas
RZ/G2L USB VBUS regulator and ST Microelectronics STM32MP13"

Pull regmap updates from Mark Brown:
"There's one new feature here, a regmap_multi_reg_read() matching the
existing write function which has some IIO users coming.
This allows atomic reads from multiple registers without the need to
wrap a higher level lock in the client driver just for regmap (which
already has locks anyway).
We also have one fix for the KUnit tests, and a bunch of cleanups"
