Pull RCU updates from Frederic Weisbecker:
"SRCU:
- Introduction of the new SRCU-lite flavour with a new pair of
srcu_read_[un]lock_lite() APIs. In practice the read side using
this flavour becomes lighter by removing a full memory barrier on
LOCK and a full memory barrier on UNLOCK. This comes at the expense
of a higher latency write side with two (in the best case of a
snaphot of unused read-sides) or more RCU grace periods on the
update side which now assumes by itself the whole full ordering
guarantee against the LOCK/UNLOCK counters on both indexes, along
with the accesses performed inside.
Uretprobes is a known potential user.
Note this doesn't replace the default normal flavour of SRCU which
still behaves the same as usual.
- Add testing of SRCU-lite through rcutorture and rcuscale
- Various cleanups on the way.
Fixes:
- Allow short-circuiting RCU-TASKS-RUDE grace periods on
architectures that have sane noinstr boundaries forbidding tracing
on low-level idle and kernel entry code. RCU-TASKS is enough on
such configurations because it involves an RCU grace period that
waits for all idle tasks to either schedule out voluntarily or
enter into RCU unwatched noinstr code.
- Allow and test start_poll_synchronize_rcu() with IRQs disabled.
- Mention rcuog kthreads in relevant documentation and Kconfig help
- Various fixes and consolidations
rcutorture:
- Add --no-affinity on tools to leave the affinity setting of guests
up to the user.
- Add guest_os_delay parameter to rcuscale for better warm-up
control.
- Fix and improve some rcuscale error handling.
- Various cleanups and fixes
stall:
- Remove dead code
- Stop dumping tasks if a stalled grace period eventually ended
midway as that only produces confusing output.
- Optimize detection of stalling CPUs and avoid useless node locking
otherwise.
NOCB:
- Fix rcu_barrier() hang due to a race against callbacks
deoffloading. This is not yet used, except by rcutorture, and waits
for its promised cpusets interface.
- Remove leftover function declaration"

page_frag test module is an out of tree module, but built
using KDIR as the main kernel tree, the mm test suite is
just getting skipped if newly added page_frag test module
fails to compile due to kernel not yet compiled.
Fix the above problem by ensuring both kernel is built first
and a newer kernel which has page_frag_cache.h is used.

Pull pidfs update from Christian Brauner:
"This adds a new ioctl to retrieve information about a pidfd.
A common pattern when using pidfds is having to get information about
the process, which currently requires /proc being mounted, resolving
the fd to a pid, and then do manual string parsing of /proc/N/status
and friends. This needs to be reimplemented over and over in all
userspace projects (e.g.: it has been reimplemented in systemd, dbus,
dbus-daemon, polkit so far), and requires additional care in checking
that the fd is still valid after having parsed the data, to avoid
races.
Having a programmatic API that can be used directly removes all these
requirements, including having /proc mounted.
As discussed at LPC24, add an ioctl with an extensible struct so that
more parameters can be added later if needed. Start with returning
pid/tgid/ppid and some creds unconditionally, and cgroupid optionally"

Pull vfs file updates from Christian Brauner:
"This contains changes the changes for files for this cycle:
- Introduce a new reference counting mechanism for files.
As atomic_inc_not_zero() is implemented with a try_cmpxchg() loop
it has O(N^2) behaviour under contention with N concurrent
operations and it is in a hot path in __fget_files_rcu().
The rcuref infrastructures remedies this problem by using an
unconditional increment relying on safe- and dead zones to make
this work and requiring rcu protection for the data structure in
question. This not just scales better it also introduces overflow
protection.
However, in contrast to generic rcuref, files require a memory
barrier and thus cannot rely on *_relaxed() atomic operations and
also require to be built on atomic_long_t as having massive amounts
of reference isn't unheard of even if it is just an attack.
This adds a file specific variant instead of making this a generic
library.
This has been tested by various people and it gives consistent
improvement up to 3-5% on workloads with loads of threads.
- Add a fastpath for find_next_zero_bit(). Skip 2-levels searching
via find_next_zero_bit() when there is a free slot in the word that
contains the next fd. This improves pts/blogbench-1.1.0 read by 8%
and write by 4% on Intel ICX 160.
- Conditionally clear full_fds_bits since it's very likely that a bit
in full_fds_bits has been cleared during __clear_open_fds(). This
improves pts/blogbench-1.1.0 read up to 13%, and write up to 5% on
Intel ICX 160.
- Get rid of all lookup_*_fdget_rcu() variants. They were used to
lookup files without taking a reference count. That became invalid
once files were switched to SLAB_TYPESAFE_BY_RCU and now we're
always taking a reference count. Switch to an already existing
helper and remove the legacy variants.
- Remove pointless includes of <linux/fdtable.h>.
- Avoid cmpxchg() in close_files() as nobody else has a reference to
the files_struct at that point.
- Move close_range() into fs/file.c and fold __close_range() into it.
- Cleanup calling conventions of alloc_fdtable() and expand_files().
- Merge __{set,clear}_close_on_exec() into one.
- Make __set_open_fd() set cloexec as well instead of doing it in two
separate steps"

Create selftests for PCIe BW control through the PCIe cooling device sysfs
interface.
First, the BW control selftest finds the PCIe Port to test with. By
default, the PCIe Port with the highest Link Speed is selected but
another PCIe Port can be provided with -d parameter.
The actual test steps the cur_state of the cooling device one-by-one
from max_state to what the cur_state was initially. The speed change
is confirmed by observing the current_link_speed for the corresponding
PCIe Port.

Check that only one notification is produced for various FDB edit

Regarding the ip_link_add() and ip_link_master() helpers. This pattern of
action plus corresponding defer is bound to come up often, and a dedicated
vocabulary to capture it will be handy. tunnel_create() and vlan_create()
from forwarding/lib.sh are somewhat opaque and perhaps too kitchen-sinky,
so I tried to go in the opposite direction with these ones, and wrapped

For logging to be useful, something has to set RET and retmsg by calling
ret_set_ksft_status(). There is a suite of functions to that end in
forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so
that every net test can use them.
Existing lib.sh users might be using these same names for their functions.
However lib.sh is always sourced near the top of the file (checked), and

Many net selftests invent their own logging helpers. These really should be
in a library sourced by these tests. Currently forwarding/lib.sh has a
suite of perfectly fine logging helpers, but sourcing a forwarding/ library
from a higher-level directory smells of layering violation. In this patch,
move the logging helpers to net/lib.sh so that every net test can use them.
Together with the logging helpers, it's also necessary to move
pause_on_fail(), and EXIT_STATUS and RET.
Existing lib.sh users might be using these same names for their functions
or variables. However lib.sh is always sourced near the top of the
file (checked), and whatever new definitions will simply override the ones

The combination of ntuple action (ring_cookie) and RSS context can
cause an ntuple rule to target a higher queue than appears in any
RSS indirection table or directly in the ntuple rule, since the two
numbers are added together. Verify the logic that prevents reducing
the queue count in this case.

Test creates an ntuple filter with 'action 2' and an RSS context whose
indirection table has entries 0 and 1. Resulting traffic should go to
queues 2 and 3; verify that it never hits queues 0 and 1.

token/obj_priv_implicit_token_envvar test may fail in an environment
where the process executing tests can not write to the root path.
Example:
https://github.com/libbpf/libbpf/actions/runs/11844507007/job/33007897936
Change default path used by the test to /tmp/bpf-token-fs, and make it
runtime configurable via an environment variable.

1. Add iocsr and mmio bus simulation in kernel.
2. Add in-kernel interrupt controller emulation.
3. Add virt extension support for eiointc irqchip.

KVM/arm64 changes for 6.13, part #1
- Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
- Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call
was introduced in PSCIv1.3 as a mechanism to request hibernation,
similar to the S4 state in ACPI
- Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
- PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
- Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
- Avoid emulated MMIO completion if userspace has requested synchronous
external abort injection
- Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests

KVM x86 misc changes for 6.13
- Clean up and optimize KVM's handling of writes to MSR_IA32_APICBASE.
- Quirk KVM's misguided behavior of initialized certain feature MSRs to
their maximum supported feature set, which can result in KVM creating
invalid vCPU state. E.g. initializing PERF_CAPABILITIES to a non-zero
value results in the vCPU having invalid state if userspace hides PDCM
from the guest, which can lead to save/restore failures.
- Fix KVM's handling of non-canonical checks for vCPUs that support LA57
to better follow the "architecture", in quotes because the actual
behavior is poorly documented. E.g. most MSR writes and descriptor
table loads ignore CR4.LA57 and operate purely on whether the CPU
supports LA57.
- Bypass the register cache when querying CPL from kvm_sched_out(), as
filling the cache from IRQ context is generally unsafe, and harden the
cache accessors to try to prevent similar issues from occuring in the
future.
- Advertise AMD_IBPB_RET to userspace, and fix a related bug where KVM
over-advertises SPEC_CTRL when trying to support cross-vendor VMs.
- Minor cleanups
