Pull irq fixes from Thomas Gleixner:
"A set of fixes for interrupt chip drivers:
- Unbreak the PLIC driver for Allwinner D1 systems
The recent conversion of the PLIC driver to a platform driver broke
Allwinnder D1 systems due to the deferred probing of platform
drivers.
Due to that the only timer available on D1 systems cannot get an
interrupt, which causes the system to hang at boot. Other RISCV
platforms are not affected because they provide the architected SBI
timer which uses the built in core interrupt controller.
Cure this by probing PLIC early on D1 systems
- Cure a regression in ARM/GIC-V3 on 32-bit ARM systems caused by the
recent addition of a initialization function, which accesses system
registers before they are enabled. On 64-bit ARM they are enabled
prior to that by sheer luck.
Ensure they are enabled.
- Cure a use before check problem in the MSI library. The existing
NULL pointer check is too late.
- Cure a lock order inversion in the ARM/GIC-V4 driver
- Fix a IS_ERR() vs. NULL pointer check issue in the RISCV APLIC
driver
- Plug a reference count leak in the ARM/GIC-V2 driver"

====================
net: mctp-serial: Fix for missing tx escapes
The mctp-serial code to add escape characters was incorrect due to an
off-by-one error. This series adds a test for the chunking which splits
by escape characters, and fixes the bug.
v2: Fix kunit param const pointer
====================

0x7d and 0x7e bytes are meant to be escaped in the data portion of
frames, but this didn't occur since next_chunk_len() had an off-by-one
error. That also resulted in the final byte of a payload being written
as a separate tty write op.
The chunk prior to an escaped byte would be one byte short, and the
next call would never test the txpos+1 case, which is where the escaped
byte was located. That meant it never hit the escaping case in
mctp_serial_tx_work().
Example Input: 01 00 08 c8 7e 80 02
Previous incorrect chunks from next_chunk_len():
01 00 08
c8 7e 80

With this fix:

We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

MGMT_OP_DISCONNECT can be called while mgmt_device_connected has not
been called yet, which will cause the connection procedure to be
aborted, so mgmt_device_disconnected shall still respond with command
complete to MGMT_OP_DISCONNECT and just not emit
MGMT_EV_DEVICE_DISCONNECTED since MGMT_EV_DEVICE_CONNECTED was never
sent.
To fix this MGMT_OP_DISCONNECT is changed to work similarly to other
command which do use hci_cmd_sync_queue and then use hci_conn_abort to
disconnect and returns the result, in order for hci_conn_abort to be
used from hci_cmd_sync context it now uses hci_cmd_sync_run_once.

On systems in the field, we are seeing this sometimes in the kernel logs:
Bluetooth: qca_controller_memdump() hci0: hci_devcd_init Return:-95
This means that _something_ decided that it wanted to get a memdump
but then hci_devcd_init() returned -EOPNOTSUPP (AKA -95).
The cleanup code in qca_controller_memdump() when we get back an error
from hci_devcd_init() undoes most things but forgets to clear
QCA_IBS_DISABLED. One side effect of this is that, during the next
suspend, qca_suspend() will always get a timeout.
Let's fix it so that we clear the bit.

Kvaser's PCIe cards uses the KCAN FPGA IP block which has dual 4K
buffers for incoming messages shared by all (currently up to eight)
channels. While the driver processes messages in one buffer, new
incoming messages are stored in the other and so on.
The design of KCAN is such that a buffer must be fully read and then
released. Releasing a buffer will make the FPGA switch buffers. If the
other buffer contains at least one incoming message the FPGA will also
instantly issue a new interrupt, if not the interrupt will be issued
after receiving the first new message.
With IRQx interrupts, it takes a little time for the interrupt to
happen, enough for any previous ISR call to do it's business and
return, but MSI interrupts are way faster so this time is reduced to
almost nothing.
So with MSI, releasing the buffer HAS to be the very last action of
the ISR before returning, otherwise the new interrupt might be
"masked" by the kernel because the previous ISR call hasn't returned.
And the interrupts are edge-triggered so we cannot loose one, or the
ping-pong reading process will stop.
This is why this patch modifies the driver to use a single write to
the SRB_CMD register before returning.

When we cork messages in psock->cork, the last message triggers the
flushing will result in sending a sk_msg larger than the current
message size. In this case, in tcp_bpf_send_verdict(), 'copied' becomes
negative at least in the following case:
468 case __SK_DROP:
469 default:
470 sk_msg_free_partial(sk, msg, tosend);
471 sk_msg_apply_bytes(psock, tosend);
472 *copied -= (tosend + delta); // <==== HERE
473 return -EACCES;
Therefore, it could lead to the following BUG with a proper value of
'copied' (thanks to syzbot). We should not use negative 'copied' as a
return value here.

io_provided_buffers_select() returns 0 to indicate success, but it should
be returning 1 to indicate that 1 vec was mapped. This causes peeking
to fail with classic provided buffers, and while that's not a use case
that anyone should use, it should still work correctly.
The end result is that no buffer will be selected, and hence a completion
with '0' as the result will be posted, without a buffer attached.

It is not safe to dereference fl->c.flc_owner without first confirming
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()
tests fl_lmops but largely ignores the result and assumes that flc_owner
is an nfs4_delegation anyway. This is wrong.
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave
as it did before the change mentioned below. This is the same as the
current code, but without any reference to a possible delegation.

For buffer registration (or updates), a userspace iovec is copied in
and updated. If the application is within a compat syscall, then the
iovec type is compat_iovec rather than iovec. However, the type used
in __io_sqe_buffers_update() and io_sqe_buffers_register() is always
struct iovec, and hence the source is incremented by the size of a
non-compat iovec in the loop. This misses every other iovec in the
source, and will run into garbage half way through the copies and
return -EFAULT to the application.
Maintain the source address separately and assign to our user vec
pointer, so that copies always happen from the right source address.
While in there, correct a bad placement of __user which triggered
the following sparse warning prior to this fix:
io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression
io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces)

Fix filemap_invalidate_inode() to use invalidate_inode_pages2_range()
rather than truncate_inode_pages_range(). The latter clears the
invalidated bit of a partial pages rather than discarding it entirely.
This causes copy_file_range() to fail on cifs because the partial pages at
either end of the destination range aren't evicted and reread, but rather
just partly cleared.
This causes generic/075 and generic/112 xfstests to fail.

sm8250 and sc7280 have lpass codec version 1.0, as these are very old
platforms, they do not have a reliable way to get the codec version
from core_id registers.
On codec versions below 2.0, even though the core_id registers are
available to read, the values of these registers are not unique to be
able to determine the version of the codec dynamically.
Add the version info into of_data, so that driver does not need to use
core_id registers to get version number for such situations.
