It is possible for a malicious device to forgo submitting a Feature

In `do_fb_ioctl()` of fbmem.c, if cmd is FBIOPUT_VSCREENINFO, var will be
copied from user, then go through `fb_set_var()` and
`info->fbops->fb_check_var()` which could may be `pm2fb_check_var()`.
Along the path, `var->pixclock` won't be modified. This function checks
whether reciprocal of `var->pixclock` is too high. If `var->pixclock` is
zero, there will be a divide by zero error. So, it is necessary to check
whether denominator is zero to avoid crash. As this bug is found by
Syzkaller, logs are listed below.

The ixgbe_ptp_start_cyclecounter is intended to be called whenever the
cyclecounter parameters need to be changed.
Since commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x
devices"), this function has cleared the SYSTIME registers and reset the
TSAUXC DISABLE_SYSTIME bit.
While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear
them during ixgbe_ptp_start_cyclecounter. This function may be called
during both reset and link status change. When link changes, the SYSTIME
counter is still operating normally, but the cyclecounter should be updated
to account for the possibly changed parameters.
Clearing SYSTIME when link changes causes the timecounter to jump because
the cycle counter now reads zero.
Extract the SYSTIME initialization out to a new function and call this
during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids
an unnecessary reset of the current time.
This also restores the original SYSTIME clearing that occurred during
ixgbe_ptp_reset before the commit above.

A race condition still exists when removing and re-creating md devices
in test cases. However, it is only seen on some setups.
The race condition was tracked down to a reference still being held
to the kobject by the rdev in the md_rdev_misc_wq which will be released
in rdev_delayed_delete().
md_alloc() waits for previous deletions by waiting on the md_misc_wq,
but the md_rdev_misc_wq may still be holding a reference to a recently
removed device.
To fix this, also flush the md_rdev_misc_wq in md_alloc().

The userspace can configure a loop using an ioctl call, wherein
a configuration of type loop_config is passed (see lo_ioctl()'s
case on line 1550 of drivers/block/loop.c). This proceeds to call
loop_configure() which in turn calls loop_set_status_from_info()
(see line 1050 of loop.c), passing &config->info which is of type
loop_info64*. This function then sets the appropriate values, like
the offset.
loop_device has lo_offset of type loff_t (see line 52 of loop.c),
which is typdef-chained to long long, whereas loop_info64 has
lo_offset of type __u64 (see line 56 of include/uapi/linux/loop.h).
The function directly copies offset from info to the device as
follows (See line 980 of loop.c):
lo->lo_offset = info->lo_offset;
This results in an overflow, which triggers a warning in iomap_iter()
due to a call to iomap_iter_done() which has:
WARN_ON_ONCE(iter->iomap.offset > iter->pos);
Thus, check for negative value during loop_set_status_from_info().

On link state change, the controller gets reset,
causing PPS to drop out and the PHC to lose its
time and calibration. So we restart it if needed,
restoring calibration and time registers.
Changes since v2:
* Add `fec_ptp_save_state()`/`fec_ptp_restore_state()`
* Use `ktime_get_real_ns()`
* Use `BIT()` macro
Changes since v1:
* More ECR #define's
* Stop PPS in `fec_ptp_stop()`

Commit 20f85ef89d94 ("drm/i915/backlight: use unique backlight device
names") added support for multiple backlight devices on dual panel
systems, but did so with error handling on -EEXIST from
backlight_device_register(). Unfortunately, that triggered a warning in
dmesg all the way down from sysfs_add_file_mode_ns() and
sysfs_warn_dup().
Instead of optimistically always attempting to register with the default
name ("intel_backlight", which we have to retain for backward
compatibility), check if a backlight device with the name exists first,
and, if so, use the card and connector based name.

If the GuC CTs are full and we need to stall the request submission
while waiting for space, we save the stalled request and where the stall
occurred; when the CTs have space again we pick up the request submission
from where we left off.
If a full GT reset occurs, the state of all contexts is cleared and all
non-guilty requests are unsubmitted, therefore we need to restart the
stalled request submission from scratch. To make sure that we do so,
clear the saved request after a reset.
Fixes note: the patch that introduced the bug is in 5.15, but no
officially supported platform had GuC submission enabled by default
in that kernel, so the backport to that particular version (and only
that one) can potentially be skipped.

Crucible + recent Mesa seems to sometimes hit:
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER)
And it looks like we can also trigger this with gem_lmem_swapping, if we
modify the test to use slightly larger object sizes.
Looking closer it looks like we have the following issues in
migrate_copy():
- We are using plain integer in various places, which we can easily
overflow with a large object.
- We pass the entire object size (when the src is lmem) into
emit_pte() and then try to copy it, which doesn't work, since we
only have a few fixed sized windows in which to map the pages and
perform the copy. With an object > 8M we therefore aren't properly
copying the pages. And then with an object > 64M we trigger the
GEM_BUG_ON(num_ccs_blks > NUM_CCS_BLKS_PER_XFER).
So it looks like our copy handling for any object > 8M (which is our
CHUNK_SZ) is currently broken on DG2.

The while loop in raspberrypi_discover_clocks() relies on the assumption
that the id of the last clock element is zero. Because this data comes
from the Videocore firmware and it doesn't guarantuee such a behavior
this could lead to out-of-bounds access. So fix this by providing
a sentinel element.

There are 2 issues:
1. We should decrement hw_resc->max_nqs instead of hw_resc->max_irqs
with the number of NQs assigned to the VFs. The IRQs are fixed
on each function and cannot be re-assigned. Only the NQs are being
assigned to the VFs.
2. vf_msix is the total number of NQs to be assigned to the VFs. So
we should decrement vf_msix from hw_resc->max_nqs.

Address learning should initially be turned off by the driver for port
operation in standalone mode, then the DSA core handles changes to it
via ds->ops->port_bridge_flags().
Leaving address learning enabled while ports are standalone breaks any
kind of communication which involves port B receiving what port A has
sent. Notably it breaks the ksz9477 driver used with a (non offloaded,
ports act as if standalone) bonding interface in active-backup mode,
when the ports are connected together through external switches, for
redundancy purposes.
This fixes a major design flaw in the ksz9477 and ksz8795 drivers, which
unconditionally leave address learning enabled even while ports operate
as standalone.

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fixes from Helge Deller:
"Some interesting background to the current patchset:
It turned out that the fldw instruction (which loads a 32-bit word
from memory into one half of a FP register) failed on unaligned
addresses and even trashed some other random FP register instead. It's
a trivial one-liner fix in the exception handler but this failure
dates back to the very beginnings of the parisc-port. It's strange
that it was never noticed before.
Another patch fixes an annoyance noticed by Randy Dunlap. Running
"make ARCH=parisc64 randconfig" always returned a 32-bit config,
although one would expect a 64-bit config. Masahiro Yamada suggested
to mimik sparc Kconfig code, which fixed the issue nicely. This
allowed to drop some compiler build checks too.
Third, it's possible to build an optimized 32-bit kernel for PA8X00
(64-bit) CPUs, which then wouldn't start on 32-bit-only (PA1.x)
machines. I've added a bootup check which prevents that and which
prints a message to the console. This can be tested with qemu, which
currently only supports 32-bit emulation.
The other patches are usual clean-up stuff like added return value
checks and typo fixes in comments.
Summary:
- Fix emulation of fldw instruction on unaligned addresses
- Fix "make ARCH=parisc64 randconfig" to return a 64-bit config
- Prevent boot if trying to boot a 32-bit kernel compiled for PA8X00

There is no need to check if the cpufreq driver implements callback
cpufreq_driver::target_index. The logic in the __resolve_freq uses
the frequency table available in the policy. It doesn't matter if the
driver provides 'target_index' or 'target' callback. It just has to
populate the 'policy->freq_table'.
Thus, check only frequency table during the frequency resolving call.
