uselib() is the legacy systemcall for loading shared libraries.
Nowadays, applications use dlopen() to load shared libraries, completely
implemented in user space via mmap().
For example, glibc uses MAP_COPY to mmap shared libraries. While this
maps to MAP_PRIVATE | MAP_DENYWRITE on Linux, Linux ignores any
MAP_DENYWRITE specification from user space in mmap.
With this change, all remaining in-tree users of MAP_DENYWRITE use it
to map an executable. We will be able to open shared libraries loaded
via uselib() writable, just as we already can via dlopen() from user
space.
This is one step into the direction of removing MAP_DENYWRITE from the
kernel. This can be considered a minor user space visible change.

This reverts commit 419dd626e3.
It turned out that the change from the reverted commit breaks the ACPI
based rpi's because it causes the 100Mhz max clock to be overridden to the
return from sdhci_iproc_get_max_clock(), which is 0 because there isn't a
OF/DT based clock device.

If the endpoint completion callback is call right after the ep_enabled flag

on the request and the associated buffer.

The issue happens only when the gadget is using the sync type "async", not
"adaptive". This indicates that problem is coming from the feedback
endpoint, which is only used with async synchronization mode.
The problem is that request is freed regardless of usb_ep_dequeue(), which
ends up badly if the request is not actually dequeued yet.
Update the feedback endpoint free function to release the endpoint the same
way it is done for the data endpoint, which takes care of the problem.

it tries to, it results in a crash like this:

This reverts commit fb926032b3.
Zhen reports that this commit slows down mq-deadline on a 128 thread
box, going from 258K IOPS to 170-180K. My testing shows that Optane
gen2 IOPS goes from 2.3M IOPS to 1.2M IOPS on a 64 thread box.
Looking in detail at the code, the main culprit here is needing to sum
percpu counters in the dispatch hot path, leading to very high CPU
utilization there. To make matters worse, the code currently needs to
sum 2 percpu counters, and it does so in the most naive way of iterating
possible CPUs _twice_.
Since we're close to release, revert this commit and we can re-do it
with regular per-priority counters instead for the 5.15 kernel.

"We received a report this week that the generic version of
pfn_valid(), which we switched to this merge window in 16c9afc776
("arm64/mm: drop HAVE_ARCH_PFN_VALID"), interacts badly with
dma_map_resource() due to the following check:
/* Don't allow RAM to be mapped */
if (WARN_ON_ONCE(pfn_valid(PHYS_PFN(phys_addr))))
return DMA_MAPPING_ERROR;
Since the ongoing saga to determine the semantics of pfn_valid() is
unlikely to be resolved this week (does it indicate valid memory, or
just the presence of a struct page, or whether that struct page has
been initialised?), just revert back to our old version of pfn_valid()

This reverts commit ce78ffa3ef.
Wren and Nicolas reported that ath11k was failing to initialise QCA6390
Wi-Fi 6 device with error:
qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22
Commit ce78ffa3ef ("net: really fix the build..."), introduced in
v5.14-rc5, caused this regression in qrtr. Most likely all ath11k
devices are broken, but I only tested QCA6390. Let's revert the broken
commit so that ath11k works again.

Pull btrfs fix from David Sterba:
"One more fix that I think qualifies for a late merge. It's a revert of
a one-liner fix that meanwhile got backported to stable kernels and we
got reports from users.
The broken fix prevents creating compressed inline extents, which
could be noticeable on space consumption.
Technically it's a regression as the patch was merged in 5.14-rc1 but
got propagated to several stable kernels and has higher exposure than
a 'typical' development cycle bug"

push_rt_task() attempts to move the currently running task away if the
next runnable task has migration disabled and therefore is pinned on the
current CPU.
The current task is retrieved via get_push_task() which only checks for
nr_cpus_allowed == 1, but does not check whether the task has migration
disabled and therefore cannot be moved either. The consequence is a
pointless invocation of the migration thread which correctly observes
that the task cannot be moved.
Return NULL if the task has migration disabled and cannot be moved to
another CPU.

The commit 71f6428332 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") moved adev assignment outside of error
path and hence made acpi_dev_put(sensor->adev) a no-op. We still
need to drop reference count on error path, and to achieve that,
replace sensor->adev by locally assigned adev.

Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.
for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on
To fix this problem, just returns user's PFC config parameter saved in
driver.

In bond 4, when the link goes down and up repeatedly, the bond may get an
unknown speed, and then this port can not work.
The driver notify netif_carrier_on() before update the link state, when the
bond receive carrier on, will query the speed of the port, if the query
operation happens before updating the link state, will get an unknown
speed. So need to notify netif_carrier_on() after update the link state.

If the port is going to send Discover_Identity Message, vdm_sm_running
flag was intentionally set before entering Ready States in order to
avoid the conflict because the port and the port partner might start
AMS at almost the same time after entering Ready States.
However, the original design has a problem. When the port is doing
DR_SWAP from Device to Host, it raises the flag. Later in the
tcpm_send_discover_work, the flag blocks the procedure of sending the
Discover_Identity and it might never be cleared until disconnection.
Since there exists another flag send_discover representing that the port
is going to send Discover_Identity or not, it is enough to use that flag
to prevent the conflict. Also change the timing of the set/clear of
vdm_sm_running to indicate whether the VDM SM is actually running or
not.
