Information for packet type is in ieee80211_tx_info
band IEEE80211_BAND_5GHZ for PK_TYPE_11A.
IEEE80211_TX_RC_USE_CTS_PROTECT via tx_rate flags selects PK_TYPE_11GB

There is pm_qos_add_request() being executed on serial_omap_probe(),
which stores "&up->pm_qos_request" from omap-serial driver to
"pm_qos_array[PM_QOS_CPU_DMA_LATENCY]->constraints". If
serial_omap_probe() fails after pm_qos_add_request() (e.g. on
uart_add_one_port() call), pm_qos_array still keeping pm_qos_request
struct from omap-serial driver, which is not valid anymore (since driver
failed). This leads further to kernel crash on pm_qos_update_target(),
executing from some completely different driver.
We were observing this while trying to run audio playback while having
one of omap-serial driver instances failed on uart_add_one_port() call:
Unable to handle kernel paging request at virtual address fffffffc

Tegra would not only need a hardware vblank counter that
increments at leading edge of vblank, but also support
for instantaneous high precision vblank timestamp queries, ie.
a proper implementation of dev->driver->get_vblank_timestamp().
Without these, there can be off-by-one errors during vblank
disable/enable if the scanout is inside vblank at en/disable
time, and additionally clients will never see any useable
vblank timestamps when querying via drmWaitVblank ioctl. This
would negatively affect swap scheduling under X11 and Wayland.

iTLB-load-misses and LLC-load-misses count incorrectly on SLM.
There is no ITLB.MISSES support on SLM. Event PAGE_WALKS.I_SIDE_WALK
should be used to count iTLB-load-misses. This event counts when an
instruction (I) page walk is completed or started. Since a page walk
implies a TLB miss, the number of TLB misses can be counted by counting
the number of pagewalks.
DMND_DATA_RD counts both demand and DCU prefetch data reads. However,
LLC-load-misses should only count demand reads. There is no way to not
include prefetches with a single counter on SLM. So the LLC-load-misses
support should be removed on SLM.

Commit 3c18d447b3 ("sched/core: Check for available DL bandwidth in
cpuset_cpu_inactive()"), a SCHED_DEADLINE bugfix, had a logic error that
caused a regression in setting a CPU inactive during suspend. I ran into
this when a program was failing pthread_setaffinity_np() with EINVAL after
a suspend+wake up.
A simple reproducer:
$ ./a.out
sched_setaffinity: Success
$ systemctl suspend
$ ./a.out
sched_setaffinity: Invalid argument
... where ./a.out is:
#define _GNU_SOURCE
#include <errno.h>
#include <sched.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
int main(void)
{
long num_cores;
cpu_set_t cpu_set;
int ret;
num_cores = sysconf(_SC_NPROCESSORS_ONLN);
CPU_ZERO(&cpu_set);
CPU_SET(num_cores - 1, &cpu_set);
errno = 0;
ret = sched_setaffinity(getpid(), sizeof(cpu_set), &cpu_set);
perror("sched_setaffinity");
return ret ? EXIT_FAILURE : EXIT_SUCCESS;
}
The mistake is that suspend is handled in the action ==
CPU_DOWN_PREPARE_FROZEN case of the switch statement in
cpuset_cpu_inactive().
However, the commit in question masked out CPU_TASKS_FROZEN
from the action, making this case dead.
The fix is straightforward.

Ronny reported that the following scenario is not handled correctly:
T1 (prio = 10)
lock(rtmutex);
T2 (prio = 20)
lock(rtmutex)
boost T1
T1 (prio = 20)
sys_set_scheduler(prio = 30)
T1 prio = 30
....
sys_set_scheduler(prio = 10)
T1 prio = 30
The last step is wrong as T1 should now be back at prio 20.
Commit c365c292d0 ("sched: Consider pi boosting in setscheduler()")
only handles the case where a boosted tasks tries to lower its
priority.
Fix it by taking the new effective priority into account for the
decision whether a change of the priority is required.

There is no need for special handling of stripe-batches when the array
is degraded.
There may be if there is a failure in the batch, but STRIPE_DEGRADED
does not imply an error.
So don't set STRIPE_BATCH_ERR in ops_run_io just because the array is
degraded.
This actually causes a bug: the STRIPE_DEGRADED flag gets cleared in
check_break_stripe_batch_list() and so the bitmap bit gets cleared
when it shouldn't.
So in check_break_stripe_batch_list(), split the batch up completely -
again STRIPE_DEGRADED isn't meaningful.
Also don't set STRIPE_BATCH_ERR when there is a write error to a
replacement device. This simply removes the replacement device and
requires no extra handling.

As the new 'scribble' array is sized based on chunk size,
we need to make sure the size matches the largest of 'old'
and 'new' chunk sizes when the array is undergoing reshape.
We also potentially need to resize it even when not resizing
the stripe cache, as chunk size can change without changing
number of devices.
So move the 'resize' code into a separate function, and
consider old and new sizes when allocating.

If any memory allocation in resize_stripes fails we will return
-ENOMEM, but in some cases we update conf->pool_size anyway.
This means that if we try again, the allocations will be assumed
to be larger than they are, and badness results.
So only update pool_size if there is no error.

Here we just align the local field names with the main system one. Then
we can add an include of the system one and delete the local copy in one
smooth step in a follow-on commit.
Not that the replacement:
for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_aci_acm_aifsn/aci_aifsn/g' $i ; done
for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_ecwmin_ecwmax/cw/g' $i ; done
for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_txop_limit/txop_limit/g' $i ; done

Currently LEAP is defined to two locally but the identically named

switch over to using the global value, we need to adjust the local

In order to start reducing the duplicated code/constants/macros in this
driver, we need to include <linux/ieee80211.h> to provide the defacto
versions. However this driver has structs with the same name as the
ones in the main include, so namespace collision prevents us from doing
step #1.
Since the structs actually differ in their respective fields, we can't
simply delete the local ones without impacting the runtime; a conversion
to use the global ones can be considered at a later date if desired.
Rename the ones here with a vendor specific prefix so that we won't have
the namespace collision, and hence can continue on with the cleanup.
Automated conversion done with:
for i in `find . -name '*.[ch]'` ; do \
sed -i 's/struct ieee80211_hdr/struct rtl_80211_hdr/g' $i ; \
