Some protocols using TCP encapsulation (e.g., espintcp, openvpn) deliver
userspace-bound packets through a custom skb queue rather than the
standard sk_receive_queue.
Introduce datagram_poll_queue that accepts an explicit receive queue,
and convert datagram_poll into a wrapper around datagram_poll_queue.
This allows protocols with custom skb queues to reuse the core polling
logic without relying on sk_receive_queue.

There are GPIO controllers such as the one present in the LX2160ARDB
QIXIS FPGA which have fixed-direction input and output GPIO lines mixed
together in a single register. This cannot be modeled using the
gpio-regmap as-is since there is no way to present the true direction of
a GPIO line.
In order to make this use case possible, add a new configuration
parameter - fixed_direction_output - into the gpio_regmap_config
structure. This will enable user drivers to provide a bitmap that
represents the fixed direction of the GPIO lines.

The madvise implementation currently resets the SVM madvise if the
underlying CPU map is unmapped. This is in an attempt to mimic the
CPU madvise behaviour. However, it's not clear that this is a desired
behaviour since if the end app user relies on it for malloc()ed
objects or stack objects, it may not work as intended.
Instead of having the autoreset functionality being a direct
application-facing implicit UAPI, make the UMD explicitly choose
this behaviour if it wants to expose it by introducing
DRM_XE_VM_BIND_FLAG_MADVISE_AUTORESET, and add a semantics
description.

Merge tag 'fsnotify_for_v6.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
Pull fsnotify fixes from Jan Kara:
- Stop-gap solution for a race between unmount of a filesystem with
fsnotify marks and someone inspecting fdinfo of fsnotify group with
those marks in procfs.
A proper solution is in the works but it will get a while to settle.
- Fix for non-decodable file handles (used by unprivileged apps using
fanotify)

The blocker tracking mechanism assumes that lock pointers are at least
4-byte aligned to use their lower bits for type encoding.
However, as reported by Eero Tamminen, some architectures like m68k
only guarantee 2-byte alignment of 32-bit values. This breaks the
assumption and causes two related WARN_ON_ONCE checks to trigger.
To fix this, the runtime checks are adjusted to silently ignore any lock
that is not 4-byte aligned, effectively disabling the feature in such
cases and avoiding the related warnings.

happens due to the combination of features and fixes, but mainly due to
commit 6d78b4473c ("bpf: Tell memcg to use allow_spinning=false path in bpf_timer_init()")
It's using __GFP_HIGH, which instructs slub/kmemleak internals to skip
kmemleak_alloc_recursive() on allocation, so subsequent kfree_rcu()->
kvfree_call_rcu()->kmemleak_ignore() complains with the above splat.
To fix this imbalance, replace bpf_map_kmalloc_node() with
kmalloc_nolock() and kfree_rcu() with call_rcu() + kfree_nolock() to
make sure that the objects allocated with kmalloc_nolock() are freed
with kfree_nolock() rather than the implicit kfree() that kfree_rcu()
uses internally.
Note, the kmalloc_nolock() happens under bpf_spin_lock_irqsave(), so
it will always fail in PREEMPT_RT. This is not an issue at the moment,
since bpf_timers are disabled in PREEMPT_RT. In the future
bpf_spin_lock will be replaced with state machine similar to
bpf_task_work.

ipv6 tunnel yet increases the headroom without any ceiling.

The setting of delay_retrans is applied to synchronous RPC operations
because the retransmit count is stored in same struct nfs4_exception
that is passed each time an error is checked. However, for asynchronous
operations (READ, WRITE, LOCKU, CLOSE, DELEGRETURN), a new struct
nfs4_exception is made on the stack each time the task callback is
invoked. This means that the retransmit count is always zero and thus
delay_retrans never takes effect.
Apply delay_retrans to these operations by tracking and updating their
retransmit count.

FF-A v1.2 introduced 16 byte IMPLEMENTATION DEFINED value in the endpoint
memory access descriptor to allow any sender could to specify an its any
custom value for each receiver. Also this value must be specified by the
receiver when retrieving the memory region. The sender must ensure it
informs the receiver of this value via an IMPLEMENTATION DEFINED mechanism
such as a partition message.
So the FF-A driver can use the message interfaces to communicate the value
and set the same in the ffa_mem_region_attributes structures when using
the memory interfaces.
The driver ensure that the size of the endpoint memory access descriptors
is set correctly based on the FF-A version.

Commit 6d4405b16d ("ata: libata-core: Cache the general purpose log
directory") introduced caching of a device general purpose log directory
to avoid repeated access to this log page during device scan. This
change also added a check on this log page to verify that the log page
version is 0x0001 as mandated by the ACS specifications.
And it turns out that some devices do not bother reporting this version,
instead reporting a version 0, resulting in error messages such as:
ata6.00: Invalid log directory version 0x0000
and to the device being marked as not supporting the general purpose log
directory log page.
Since before commit 6d4405b16d the log page version check did not
exist and things were still working correctly for these devices, relax
ata_read_log_directory() version check and only warn about the invalid
log page version number without disabling access to the log directory
page.

Pull more x86 updates from Borislav Petkov:
- Remove a bunch of asm implementing condition flags testing in KVM's
emulator in favor of int3_emulate_jcc() which is written in C
- Replace KVM fastops with C-based stubs which avoids problems with the
fastop infra related to latter not adhering to the C ABI due to their
special calling convention and, more importantly, bypassing compiler
control-flow integrity checking because they're written in asm
- Remove wrongly used static branches and other ugliness accumulated
over time in hyperv's hypercall implementation with a proper static
function call to the correct hypervisor call variant
- Add some fixes and modifications to allow running FRED-enabled
kernels in KVM even on non-FRED hardware
- Add kCFI improvements like validating indirect calls and prepare for
enabling kCFI with GCC. Add cmdline params documentation and other
code cleanups
- Use the single-byte 0xd6 insn as the official #UD single-byte
undefined opcode instruction as agreed upon by both x86 vendors
- Other smaller cleanups and touchups all over the place
