"During the merge window an issue with si_perf and the siginfo ABI came
up. The alpha and sparc siginfo structure layout had changed with the
addition of SIGTRAP TRAP_PERF and the new field si_perf.
The reason only alpha and sparc were affected is that they are the
only architectures that use si_trapno.
Looking deeper it was discovered that si_trapno is used for only a few
select signals on alpha and sparc, and that none of the other
_sigfault fields past si_addr are used at all. Which means technically
no regression on alpha and sparc.
While the alignment concerns might be dismissed the abuse of si_errno
by SIGTRAP TRAP_PERF does have the potential to cause regressions in
existing userspace.
While we still have time before userspace starts using and depending
on the new definition siginfo for SIGTRAP TRAP_PERF this set of
changes cleans up siginfo_t.
- The si_trapno field is demoted from magic alpha and sparc status
and made an ordinary union member of the _sigfault member of
siginfo_t. Without moving it of course.
- si_perf is replaced with si_perf_data and si_perf_type ending the
abuse of si_errno.
- Unnecessary additions to signalfd_siginfo are removed"

The return value of hga_card_detect() is not properly handled causing
the probe to succeed even though hga_card_detect() failed. Since probe
succeeds, hgafb_open() can be called which will end up operating on an
unmapped hga_vram. This results in an out-of-bounds access as reported
by kernel test robot [1].
To fix this, correctly detect failure of hga_card_detect() by checking
for a non-zero error code.

It's possible that the interrupt handler for the UCSI driver signals a
connector changes after the handler clears the PENDING bit, but before
it has sent the acknowledge request. The result is that the handler is
invoked yet again, to ack the same connector change.
At least some versions of the Qualcomm UCSI firmware will not handle the
second - "spurious" - acknowledgment gracefully. So make sure to not
clear the pending flag until the change is acknowledged.
Any connector changes coming in after the acknowledgment, that would
have the pending flag incorrectly cleared, would afaict be covered by
the subsequent connector status check.

The driver incorrectly uses req->num_pending_sgs to track both the
number of pending and queued SG entries. It only prepares the next
request if the previous is done, and it doesn't update num_pending_sgs
until there is TRB completion interrupt. This may starve the controller
of more TRBs until the num_pending_sgs is decremented.
Fix this by decrementing the num_pending_sgs after they are queued and
properly track both num_mapped_sgs and num_queued_sgs.

Syzbot found that the kernel generates a WARNing if the user tries to
submit a bulk transfer through usbfs with a buffer that is way too
large. This isn't a bug in the kernel; it's merely an invalid request
from the user and the usbfs code does handle it correctly.
In theory the same thing can happen with async transfers, or with the
packet descriptor table for isochronous transfers.
To prevent the MM subsystem from complaining about these bad
allocation requests, add the __GFP_NOWARN flag to the kmalloc calls
for these buffers.

Allow SPI peripherals attached to this controller to know what is the
maximum transfer size and message size, so they can limit their transfer
lengths properly in case they are otherwise capable of larger transfer
sizes. For the sc18is602, this is 200 bytes in both cases, since as far
as I understand, it isn't possible to tell the controller to keep the
chip select asserted after the STOP command is sent.
The controller can support SPI messages larger than 200 bytes if
cs_change is set for individual transfers such that the portions with
chip select asserted are never longer than 200 bytes. What is not
supported is just SPI messages with a continuous chip select larger than
200. I don't think it is possible to express this using the current API,
so drivers which do send SPI messages with cs_change can safely just
look at the max_transfer_size limit.
An example of user for this is sja1105_xfer() in
drivers/net/dsa/sja1105/sja1105_spi.c which sends by default 64 * 4 =
256 byte transfers.

For each spi_message, the sc18is602 I2C-to-SPI bridge driver checks the
length of each spi_transfer against 200 (the size of the chip's internal
buffer) minus hw->tlen (the number of bytes transferred so far).
The first byte of the transferred data is the Function ID (the SPI
slave's chip select) and as per the documentation of the chip:
https://www.nxp.com/docs/en/data-sheet/SC18IS602B.pdf
the data buffer is up to 200 bytes deep _without_ accounting for the
Function ID byte.
However, in sc18is602_txrx(), the driver keeps the Function ID as part
of the buffer, and increments hw->tlen from 0 to 1. Combined with the
check in sc18is602_check_transfer, this prevents us from issuing a
transfer that has exactly 200 bytes in size, but only 199.
Adjust the check function to reflect that the Function ID is not part of
the 200 byte deep data buffer.

soundwire fixes for v5.13
Fix in qcom driver for handling of qcom,ports-block-pack-mode property.
This fixes regression reported in DragonBoard DB845c and Lenovo Yoga
C630.

To avoid a NULL pointer dereference when the kernel supports the new
feature but the tooling still hasn't an entry for it.
This happened with the recently added PERF_COUNT_SW_CGROUP_SWITCHES
software event.

When multiple PCI devices get assigned to a guest right at boot, libxl
incrementally populates the backend tree. The writes for the first of
the devices trigger the backend watch. In turn xen_pcibk_setup_backend()
will set the XenBus state to Initialised, at which point no further
reconfigures would happen unless a device got hotplugged. Arrange for
reconfigure to also get triggered from the backend watch handler.

The commit referenced below was incomplete: It merely affected what
would get written to the vdev-<N> xenstore node. The guest would still
find the function at the original function number as long as
__xen_pcibk_get_pci_dev() wouldn't be in sync. The same goes for AER wrt
__xen_pcibk_get_pcifront_dev().
Undo overriding the function to zero and instead make sure that VFs at
function zero remain alone in their slot. This has the added benefit of
improving overall capacity, considering that there's only a total of 32
slots available right now (PCI segment and bus can both only ever be
zero at present).

xen_setup_gdt(), via xen_load_gdt_boot(), wants to adjust page tables.
For this to work when NX is not available, x86_configure_nx() needs to
be called first.
[jgross] Note that this is a revert of 36104cb901 ("x86/xen:
Delay get_cpu_cap until stack canary is established"), which is possible
now that we no longer support running as PV guest in 32-bit mode.

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for drivers/net/ethernet/microchip/encx24j600 files follows
this syntax, but the content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc.
For e.g., running scripts/kernel-doc -none
drivers/net/ethernet/microchip/encx24j600_hw.h emits:
warning: expecting prototype for h(). Prototype was for _ENCX24J600_HW_H() instead
Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

problematic when it's used in combination with skb_redirect_peer().
Without it, redirecting a packet from a L3 device such as wireguard to

IP header on entry to tcp_v4_rcv() since the L2 header is not pulled

The cppcheck static code analysis reported the following error:
if (WARN_ON_ONCE(nest_level > ARRAY_SIZE(bufs->tmp_bufs))) {
^
ARRAY_SIZE is a macro that expands to sizeofs, so bufs is not actually
dereferenced at runtime, and the code is actually safe. But to keep
things tidy, this patch removes the need for a call to ARRAY_SIZE by
extracting the size of the array into a macro. Cppcheck should no longer
be confused and the code ends up being a bit cleaner.
