In debugging platform or firmware related MEI-PXP connection
issues, having a timeout when clients (such as i915) calling
into mei-pxp's send/receive functions have proven useful as opposed to
blocking forever until the kernel triggers a watchdog panic (when
platform issues are experienced).

The existing implementation support only 32-bit DMA operation.
So, it fails to load the bitstream for the high DDR designs(Beyond 4GB).
To fix this issue update the DMA mask handling logic to support 44-bit

Use preferred spi_get_device_match_data() instead of of_match_device() and
spi_get_device_id() to get the driver match data. With this, adjust the
includes to explicitly include the correct headers.

Also drop of_match_ptr for of_ef_match, which is not necessary because DT
is always used for this driver.

This reverts commit 45e34c8a, and the
two subsequent fixes to it:

  3f874c9b ("x86/smp: Don't send INIT to non-present and non-booted CPUs")
  b1472a60 ("x86/smp: Don't send INIT to boot CPU")

because it seems to result in hung machines at shutdown.  Particularly
some Dell machines, but Thomas says

 "The rest seems to be Lenovo and Sony with Alderlake/Raptorlake CPUs -
  at least that's what I could figure out from the various bug reports.

  I don't know which CPUs the DELL machines have, so I can't say it's a
  pattern.

  I agree with the revert for now"

Ashok Raj chimes in:

 "There was a report (probably this same one), and it turns out it was a
  bug in the BIOS SMI handler.

  The client BIOS's were waiting for the lowest APICID to be the SMI
  rendevous master. If this is MeteorLake, the BSP wasn't the one with
  the lowest APIC and it triped here.

  The BIOS change is also being pushed to others for assimilation :)

  Server BIOS's had this correctly for a while now"

and it does look likely to be some bad interaction between SMI and the
non-BSP cores having put into INIT (and thus unresponsive until reset).

Commit 295525e2 ("virtio_net: merge dma operations when filling
mergeable buffers") unmaps the buffer with DMA_ATTR_SKIP_CPU_SYNC when
the dma->ref is zero. We do that with DMA_ATTR_SKIP_CPU_SYNC, because we
do not want to do the sync for the entire page_frag. But that misses the
sync for the current area.

This patch does cpu sync regardless of whether the ref is zero or not.

Kernel v6.5 converted overlayfs to new mount api.
As an added bonus, it also added a feature to allow appending lowerdirs
using lowerdir=:/lower2,lowerdir=::/data3 syntax.

This new syntax has raised some concerns regarding escaping of colons.
We decided to try and disable this syntax, which hasn't been in the wild
for so long and introduce it again in 6.7 using explicit mount options
lowerdir+=/lower2,datadir+=/data3.

Before commit b36a5780 ("ovl: modify layer parameter parsing"),
spaces and commas in lowerdir mount option value used to be escaped using
seq_show_option().

In current upstream, when lowerdir value has a space, it is not escaped
in /proc/mounts, e.g.:

  none /mnt overlay rw,relatime,lowerdir=l l,upperdir=u,workdir=w 0 0

which results in broken output of the mount utility:

  none on /mnt type overlay (rw,relatime,lowerdir=l)

Store the original lowerdir mount options before unescaping and show
them using the same escaping used for seq_show_option() in addition to
escaping the colon separator character.

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct.  When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.

The issue was uncovered when in 92e24e0e ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.

Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.
