The generic_handle_domain_irq() function resolves the hardware IRQ
internally. The driver performed a duplicative mapping by calling
irq_find_mapping() first, which could lead to an RCU stall.
Delete the redundant irq_find_mapping() call and pass the hardware IRQ
directly to generic_handle_domain_irq().

If the send_peer_notif counter and the peer event notify are not synchronized.
It may cause problems such as the loss or dup of peer notify event.
Before this patch:
- If should_notify_peers is true and the lock for send_peer_notif-- fails, peer
event may be sent again in next mii_monitor loop, because should_notify_peers
is still true.
- If should_notify_peers is true and the lock for send_peer_notif-- succeeded,
but the lock for peer event fails, the peer event will be lost.
This patch locks the RTNL for send_peer_notif, events, and commit simultaneously.

Commit 16c07342b542 ("gpiolib: acpi: Program debounce when finding GPIO")
adds a gpio_set_debounce_timeout() call to acpi_find_gpio() and makes
acpi_find_gpio() fail if this fails.
But gpio_set_debounce_timeout() failing is a somewhat normal occurrence,
since not all debounce values are supported on all GPIO/pinctrl chips.
Making this an error for example break getting the card-detect GPIO for
the micro-sd slot found on many Bay Trail tablets, breaking support for
the micro-sd slot on these tablets.
acpi_request_own_gpiod() already treats gpio_set_debounce_timeout()
failures as non-fatal, just warning about them.
Add a acpi_gpio_set_debounce_timeout() helper which wraps
gpio_set_debounce_timeout() and warns on failures and replace both existing
gpio_set_debounce_timeout() calls with the helper.
Since the helper only warns on failures this fixes the card-detect issue.

The phmac implementation used the req->nbytes field on combined
operations (finup, digest) to track the state:
with req->nbytes > 0 the update needs to be processed,
while req->nbytes == 0 means to do the final operation. For
this purpose the req->nbytes field was set to 0 after successful
update operation. However, aead uses the req->nbytes field after a
successful hash operation to determine the amount of data to
en/decrypt. So an implementation must not modify the nbytes field.
Fixed by a slight rework on the phmac implementation. There is
now a new field async_op in the request context which tracks
the (asynch) operation to process. So the 'state' via req->nbytes
is not needed any more and now this field is untouched and may
be evaluated even after a request is processed by the phmac
implementation.

'net-ravb-fix-soc-specific-configuration-and-descriptor-handling-issues'
Lad Prabhakar says:
====================
net: ravb: Fix SoC-specific configuration and descriptor handling issues [part]
This series addresses several issues in the Renesas Ethernet AVB (ravb)
driver related descriptor ordering.
A potential ordering hazard in descriptor setup could cause
the DMA engine to start prematurely, leading to TX stalls on some
platforms.
The series includes the following changes:
Enforce descriptor type ordering to prevent early DMA start
Ensure proper write ordering of TX descriptor type fields to prevent the
DMA engine from observing an incomplete descriptor chain. This fixes
observed TX stalls on RZ/G2L platforms running RT kernels.
Tested on R/G1x Gen2, RZ/G2x Gen3 and RZ/G2L family hardware.

Add a final dma_wmb() barrier before triggering the transmit request
(TCCR_TSRQ) to ensure all descriptor and buffer writes are visible to
the DMA engine.
According to the hardware manual, a read-back operation is required
before writing to the doorbell register to guarantee completion of
previous writes. Instead of performing a dummy read, a dma_wmb() is
used to both enforce the same ordering semantics on the CPU side and
also to ensure completion of writes.

Ensure the TX descriptor type fields are published in a safe order so the
DMA engine never begins processing a descriptor chain before all descriptor
fields are fully initialised.
For multi-descriptor transmits the driver writes DT_FEND into the last
descriptor and DT_FSTART into the first. The DMA engine begins processing
when it observes DT_FSTART. Move the dma_wmb() barrier so it executes
immediately after DT_FEND and immediately before writing DT_FSTART
(and before DT_FSINGLE in the single-descriptor case). This guarantees
that all prior CPU writes to the descriptor memory are visible to the
device before DT_FSTART is seen.
This avoids a situation where compiler/CPU reordering could publish
DT_FSTART ahead of DT_FEND or other descriptor fields, allowing the DMA to
start on a partially initialised chain and causing corrupted transmissions
or TX timeouts. Such a failure was observed on RZ/G2L with an RT kernel as
transmit queue timeouts and device resets.

This makes the logic to prevent on overflow of
the send submission queue with ib_post_send() easier.
As we first get a local credit and then a remote credit
before we mark us as pending.
For now we'll keep the logic around smbdirect_socket.send_io.pending.*,
but that will likely change or be removed completely.
The server will get a similar logic soon, so
we'll be able to share the send code in future.

smb_direct_flush_send_list/send_done
We have a list handling that is much easier to understand:
1. Before smb_direct_flush_send_list() is called all
struct smbdirect_send_io messages are part of
send_ctx->msg_list
2. Before smb_direct_flush_send_list() calls
smb_direct_post_send() we remove the last
element in send_ctx->msg_list and move all
others into last->sibling_list. As only
last has IB_SEND_SIGNALED and gets a completion
vis send_done().
3. send_done() has an easy way to free all others
in sendmsg->sibling_list (if there are any).
And use list_for_each_entry_safe() instead of
a complex custom logic.
This will help us to share send_done() in common
code soon, as it will work fine for the client too,
where last->sibling_list is currently always an empty list.

This will be used to implement a logic in order to make sure
we don't overflow the send submission queue for ib_post_send().
We will initialize the local credits with the
fixed sp->send_credit_target value, which matches
the reserved slots in the submission queue for ib_post_send().
We will be a local credit first and then wait for a remote credit,
if we managed to get both we are allowed to post an
IB_WR_SEND[_WITH_INV]. The local credit is given back to
the pool when we get the local ib_post_send() completion,
while remote credits are granted by the peer.
From reading the git history of the linux smbdirect
implementations in client and server) it was seen
that a peer granted more credits than we requested.
I guess that only happened because of bugs in our
implementation which was active as client and server.
I guess Windows won't do that.
So the local credits make sure we only use the amount
of credits we asked for.
The client already has some logic for this based on
smbdirect_socket.send_io.pending.count, but that
counts in the order direction and makes it complex it
share common logic for various credits classes.
That logic will be replaced soon.

And rely on rdma_rw_init_qp() to setup ib_mr_pool_init() for
RW MRs. ib_mr_pool_destroy() will be called by rdma_rw_cleanup_mrs().
It seems the code was implemented before the rdma_rw_* layer
was fully established in the kernel.
While there also add additional space for ib_drain_qp().
This should make sure ib_post_send() will never fail
because the submission queue is full.

Restore the dependency of the architecture-optimized Poly1305 code on
!KMSAN. It was dropped by commit b646b782e522 ("lib/crypto: poly1305:
Consolidate into single module").
Unlike the other hash algorithms in lib/crypto/ (e.g., SHA-512), the way
the architecture-optimized Poly1305 code is integrated results in
assembly code initializing memory, for several different architectures.
Thus, it generates false positive KMSAN warnings. These could be
suppressed with kmsan_unpoison_memory(), but it would be needed in quite
a few places. For now let's just restore the dependency on !KMSAN.
Note: this should have been caught by running poly1305_kunit with
CONFIG_KMSAN=y, which I did. However, due to an unrelated KMSAN bug
(https://lore.kernel.org/r/20251022030213.GA35717@sol/), KMSAN currently
isn't working reliably. Thus, the warning wasn't noticed until later.

The current approach is a bit naive, and hence calls the time querying
way too often. Only start the "doing work" timer when there's actual
work to do, and then use that information to terminate (and account) the
work time once done. This greatly reduces the frequency of these calls,
when they cannot have changed anyway.
Running a basic random reader that is setup to use SQPOLL, a profile
before this change shows these as the top cycle consumers:

According to Maciej W. Rozycki <macro@orcam.me.uk>, the
mips_pcibios_init() for malta adjusts root bus IO resource start
address to prevent interfering with PIIX4 I/O cycle decoding. Adjusting
lower bound leaves PIIX4 IO resources outside of the root bus resource
and assign_fixed_resource_on_bus() does not link the resources into the
resource tree.
Prior to commit ae81aad5c2e1 ("MIPS: PCI: Use pci_enable_resources()") the
arch specific pcibios_enable_resources() did not check if the resources
were assigned which diverges from what PCI core checks, effectively hiding
the PIIX4 IO resources were not properly within the resource tree. After
starting to use pcibios_enable_resources() from PCI core, enabling PIIX4
fails:
ata_piix 0000:00:0a.1: BAR 0 [io 0x01f0-0x01f7]: not claimed; can't enable device
ata_piix 0000:00:0a.1: probe with driver ata_piix failed with error -22
MIPS PCI code already has support for enforcing lower bounds using
PCIBIOS_MIN_IO in pcibios_align_resource() without altering the IO window
start address itself. Make malta PCI code too to use PCIBIOS_MIN_IO.

Covering the PCI southbridge legacy port I/O range with a northbridge
resource reservation prevents MIPS Malta platform code from claiming its
standard legacy resources. This is because request_resource() calls
cause a clash with the previous reservation and consequently fail.
Change to using insert_resource() so as to prevent the clash, switching
the legacy reservations from:
00000000-00ffffff : MSC PCI I/O
00000020-00000021 : pic1
00000070-00000077 : rtc0

MIPS Malta platform code registers the PCI southbridge legacy port I/O
PS/2 keyboard range as a standard resource marked as busy. It prevents
the i8042 driver from registering as it fails to claim the resource in
a call to i8042_platform_init(). Consequently PS/2 keyboard and mouse
devices cannot be used with this platform.
Fix the issue by removing the busy marker from the standard reservation,
making the driver register successfully:
serio: i8042 KBD port at 0x60,0x64 irq 1
serio: i8042 AUX port at 0x60,0x64 irq 12
and the resource show up as expected among the legacy devices:
00000000-00ffffff : MSC PCI I/O
00000000-0000001f : dma1
00000020-00000021 : pic1

000000a0-000000a1 : pic2
000000c0-000000df : dma2
[...]
If the i8042 driver has not been configured, then the standard resource
will remain there preventing any conflicting dynamic assignment of this
PCI port I/O address range.

The block layer PI generation / verification code expects the bio_vecs
to have at least LBA size (or more correctly integrity internal)
granularity. With the direct I/O alignment relaxation in 2022, user
space can now feed bios with less alignment than that, leading to
scribbling outside the PI buffers. Apparently this wasn't noticed so far
because none of the tests generate such buffers, but since 851c4c96db00
("xfs: implement XFS_IOC_DIOINFO in terms of vfs_getattr"), xfstests
generic/013 by default generates such I/O now that the relaxed alignment
is advertised by the XFS_IOC_DIOINFO ioctl.
Fix this by increasing the required alignment when using PI, although
handling arbitrary alignment in the long run would be even nicer.

In of_msi_get_domain() if the iterator loop stops early because an
irq_domain match is detected, an of_node_put() on the iterator node is
needed to keep the OF node refcount in sync.
Add it.

In some legacy platforms the MSI controller for a PCI host bridge is
identified by an msi-parent property whose phandle points at an MSI
controller node with no #msi-cells property, that implicitly
means #msi-cells == 0.
For such platforms, mapping a device ID and retrieving the MSI controller
node becomes simply a matter of checking whether in the device hierarchy
there is an msi-parent property pointing at an MSI controller node with
such characteristics.
Add a helper function to of_msi_xlate() to check the msi-parent property in
addition to msi-map and retrieve the MSI controller node (with a 1:1 ID
deviceID-IN<->deviceID-OUT mapping) to provide support for deviceID
mapping and MSI controller node retrieval for such platforms.

The SPI controller found in the RK3506 SoC is still compatible to the
original one introduced with the RK3066, so add the RK3506 compatible
to the list of its variants.
