Commit 057996380a42 ("bpf: Add batch ops to all htab bpf map")
added lookup_and_delete batch operation for hash table.
The current implementation has bpf_lru_push_free() inside
the bucket lock, which may cause a deadlock.

*** DEADLOCK ***
To fix the issue, for htab_lru_map_lookup_and_delete_batch() in CPU0,
let us do bpf_lru_push_free() out of the htab bucket lock. This can
avoid the above deadlock scenario.

Grabbing the spinlock for every bucket even if it's empty, was causing
significant perfomance cost when traversing htab maps that have only a
few entries. This patch addresses the issue by checking first the
bucket_cnt, if the bucket has some entries then we go and grab the
spinlock and proceed with the batching.
Tested with a htab of size 50K and different value of populated entries.

Implemented small fix so that the script changes work directories to the
root of the linux kernel source tree from which kunit.py is run. This
enables the user to run kunit from any working directory. Originally
considered using os.path.join but this is more error prone as we would
have to find all file path usages and modify them accordingly. Using
os.chdir ensures that the entire script is run within /linux.

The configuration/command below is failing when the VF in the xml
file is already bound to the host iavf driver.
pci_0000_af_0_0.xml:
<interface type='hostdev' managed='yes'>
<source>
<address type='pci' domain='0x0000' bus='0xaf' slot='0x0' function='0x0'/>
</source>
<mac address='00:de:ad:00:11:01'/>
</interface>
> virsh attach-device domain_name pci_0000_af_0_0.xml
error: Failed to attach device from pci_0000_af_0_0.xml
error: Cannot set interface MAC/vlanid to 00:de:ad:00:11:01/0 for
ifname ens1f1 vf 0: Device or resource busy
This is failing because the VF has not been completely removed/reset
after being unbound (via the virsh command above) from the host iavf
driver and ice_set_vf_mac() checks if the VF is disabled before waiting
for the reset to finish.
Fix this by waiting for the VF remove/reset process to happen before
checking if the VF is disabled. Also, since many functions for VF
administration on the PF were more or less calling the same 3 functions
(ice_wait_on_vf_reset(), ice_is_vf_disabled(), and ice_check_vf_init())
move these into the helper function ice_check_vf_ready_for_cfg(). Then
call this function in any flow that attempts to configure/query a VF
from the PF.
Lastly, increase the maximum wait time in ice_wait_on_vf_reset() to
800ms, and modify/add the #define(s) that determine the wait time.
This was done for robustness because in rare/stress cases VF removal can
take a max of ~800ms and previously the wait was a max of ~300ms.

Remove code that tell the OS that link is going down when user
change flow control via ethtool. When link is up it isn't certain
that link goes down after 0x0605 aq command. If link doesn't go
down, OS thinks that link is down, but physical link is up. To
reset this state user have to take interface down and up.
If link goes down after 0x0605 command, FW send information
about that and after that driver tells the OS that the link goes
down. So this code in ethtool is unnecessary.

Currently if a user sets an odd [tx|rx]-usecs value through ethtool,
the request is denied because the hardware is set to have an ITR
granularity of 2us. This caused poor customer experience. Fix this by
aligning to a register allowed value, which results in rounding down.
Also, print a once per ring container type message to be clear about
our intentions.
Also, change the ITR_TO_REG define to be the bitwise and of the ITR
setting and the ICE_ITR_MASK. This makes the purpose of ITR_TO_REG more
obvious.

The PN544 driver checks the "enable" polarity during of driver's probe and
it's doing that by turning ON and OFF NFC with different polarities until
enabling succeeds. It takes some time for the hardware to power-down, and
thus, to deassert the IRQ that is raised by turning ON the hardware.
Since the delay after last power-down of the polarity-checking process is
missed in the code, the interrupt may trigger immediately after installing
the IRQ handler (right after the checking is done), which results in IRQ
handler trying to touch the disabled HW and ends with marking NFC as
'DEAD' during of the driver's probe:
pn544_hci_i2c 1-002a: NFC: nfc_en polarity : active high
pn544_hci_i2c 1-002a: NFC: invalid len byte
shdlc: llc_shdlc_recv_frame: NULL Frame -> link is dead
This patch fixes the occasional NFC initialization failure on Nexus 7
device.

Commit
aaf248848db50 ("perf/x86/msr: Add AMD IRPERF (Instructions Retired)

added support for access to the free-running counter via 'perf -e

BEFORE:
$ perf stat -e instructions,msr/irperf/ true
Performance counter stats for 'true':
624,833 instructions
0 msr/irperf/
Simply set its enable bit - HWCR bit 30 - to make it start counting.
Enablement is restricted to all machines advertising IRPERF capability,
except those susceptible to an erratum that makes the IRPERF return
bad values.
That erratum occurs in Family 17h models 00-1fh [1], but not in F17h
models 20h and above [2].
AFTER (on a family 17h model 31h machine):
$ perf stat -e instructions,msr/irperf/ true
Performance counter stats for 'true':
621,690 instructions
622,490 msr/irperf/

This reverts commit 219d2e9dfda9431b808c28d5efc74b404b95b638.
The call chain below requires the cm_id_priv's destination address to be
setup before performing rdma_bind_addr(). Otherwise source port allocation
fails as cma_port_is_unique() no longer sees the correct tuple to allow
duplicate users of the source port.
rdma_resolve_addr()
cma_bind_addr()
rdma_bind_addr()
cma_get_port()
cma_alloc_any_port()
cma_port_is_unique() <- compared with zero daddr
This can result in false failures to connect, particularly if the source
port range is restricted.

The RK3328 reference design uses an external line driver IC as a buffer
on the analog codec output, enabled by the GPIO_MUTE pin, and such a
configuration is currently assumed in the codec driver's direct poking
of GRF_SOC_CON10 to control the GPIO_MUTE output value. However, some
boards wire up analog audio yet use that pin for some other purpose, so
that assumption doesn't always hold. Update this functionality to rely
on an explicit GPIO descriptor, such that it can be managed at the
board level.

Existing RK3328 codec drivers have overloaded the GRF phandle to assume
implicit control of the limited-function GPIO_MUTE pin, which is usually
used to enable an external audio line driver IC. Since this pin has a
proper binding of its own (see gpio/rockchip,rk3328-grf-gpio.txt), make
a GPIO explicit in the codec binding too. This will help avoid ambiguity
on boards that use that pin for some other purpose.
(and while touching the example, enforce the "don't include status" rule)

Use the existence of the workqueue itself to determine when to
enable HDCP features rather than sprinkling asic checks all over
the code. Also add a check for the existence of the hdcp
workqueue in the irq handling on the off chance we get and HPD
RX interrupt with the CP bit set. This avoids a crash if
the driver doesn't support HDCP for a particular asic.

This reverts commit b2354e4009a773c00054b964d937e1b81cb92078.
This change might have been desirable to ensure the uniqueness of
the component name. It would have helped to better support linux
devices which register multiple components, something is which more
common than initially thought.
However, some card driver are directly using dev_name() to fill the
component names of the dai_link which is a problem if want to change
the way ASoC generates the component names.
Until we figure out the appropriate way to deal with this, revert the
change and keep the names as they were. There might be a couple of warning
related to debugfs (which were already present before the change) but it
is still better than breaking working audio cards.

dpcm_show_state() invokes multiple snprintf() calls to concatenate
formatted strings on the fixed size buffer. The usage of snprintf()
is supposed for avoiding the buffer overflow, but it doesn't work as
expected because snprintf() doesn't return the actual output size but
the size to be written.
Fix this bug by replacing all snprintf() calls with scnprintf()
calls.
