That comes from the call to kuap_loc(), allthough __kuap_lock() is an
empty function on the 8xx.

To avoid that, only perform kuap_is_disabled() check when there is
something to do with __kuap_lock().

Do the same with __kuap_save_and_lock() and
__kuap_get_and_assert_locked().

880df2d46a powerpc/kuap: Avoid unnecessary reads of MD_AP
A disassembly of interrupt_exit_kernel_prepare() shows a useless read
of MD_AP register. This is shown by r9 being re-used immediately without
doing anything with the value read.

  c000e0e0:       60 00 00 00     nop
  c000e0e4: ===>  7d 3a c2 a6     mfmd_ap r9	<====

  c000e0f4:       71 29 80 00     andi.   r9,r9,32768

kuap_get_and_assert_locked() is paired with kuap_kernel_restore()
and are only used in interrupt_exit_kernel_prepare(). The value
returned by kuap_get_and_assert_locked() is only used by
kuap_kernel_restore().

On 8xx, kuap_kernel_restore() doesn't use the value read by
kuap_get_and_assert_locked() so modify kuap_get_and_assert_locked()
to not perform the read of MD_AP and return 0 instead.

The same applies on BOOKE.

72c8caf904 wifi: ath11k: fix band selection for ppdu received in channel 177 of 5 GHz
5 GHz band channel 177 support was added with the commit e5e94d10c8 ("wifi:
ath11k: add channel 177 into 5 GHz channel list"). However, during processing
for the received ppdu in ath11k_dp_rx_h_ppdu(), channel number is checked only
till 173. This leads to driver code checking for channel and then fetching the
band from it which is extra effort since firmware has already given the channel
number in the metadata.

Fix this issue by checking the channel number till 177 since we support
it now.

Found via code review. Compile tested only.

16e455a465 wifi: brcmfmac: Fix field-spanning write in brcmf_scan_params_v2_to_v1()
Using brcmfmac with 6.5-rc3 on a brcmfmac43241b4-sdio triggers
a backtrace caused by the following field-spanning warning:

memcpy: detected field-spanning write (size 120) of single field
  "&params_le->channel_list[0]" at
  drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c:1072 (size 2)

The driver still works after this warning. The warning was introduced by the
new field-spanning write checks which were enabled recently.

Fix this by replacing the channel_list[1] declaration at the end of
the struct with a flexible array declaration.

Most users of struct brcmf_scan_params_le calculate the size to alloc
using the size of the non flex-array part of the struct + needed extra
space, so they do not care about sizeof(struct brcmf_scan_params_le).

brcmf_notify_escan_complete() however uses the struct on the stack,
expecting there to be room for at least 1 entry in the channel-list
to store the special -1 abort channel-id.

To make this work use an anonymous union with a padding member
added + the actual channel_list flexible array.

d6b484b5cb wifi: mt76: Replace strlcpy() with strscpy()
strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().

Direct replacement is safe here since DEV_ASSIGN is only used by
TRACE macros and the return values are ignored.

0756384fb1 vxlan: Fix nexthop hash size
The nexthop code expects a 31 bit hash, such as what is returned by
fib_multipath_hash() and rt6_multipath_hash(). Passing the 32 bit hash
returned by skb_get_hash() can lead to problems related to the fact that
'int hash' is a negative number when the MSB is set.

In the case of hash threshold nexthop groups, nexthop_select_path_hthr()
will disproportionately select the first nexthop group entry. In the case
of resilient nexthop groups, nexthop_select_path_res() may do an out of
bounds access in nh_buckets[], for example:
    hash = -912054133
    num_nh_buckets = 2
    bucket_index = 65535

which leads to the following panic:

27bcd12295 Merge branch 'icssg-driver'
MD Danish Anwar says:

====================
Introduce ICSSG based ethernet Driver

The Programmable Real-time Unit and Industrial Communication Subsystem
Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI
SoCs. This subsystem is provided for the use cases like the implementation
of custom peripheral interfaces, offloading of tasks from the other
processor cores of the SoC, etc.

The subsystem includes many accelerators for data processing like
multiplier and multiplier-accumulator. It also has peripherals like
UART, MII/RGMII, MDIO, etc. Every ICSSG core includes two 32-bit
load/store RISC CPU cores called PRUs.

The above features allow it to be used for implementing custom firmware
based peripherals like ethernet.

This series adds the YAML documentation and the driver with basic EMAC
support for TI AM654 Silicon Rev 2 SoC with the PRU_ICSSG Sub-system.
running dual-EMAC firmware.
This currently supports basic EMAC with 1Gbps and 100Mbps link. 10M and
half-duplex modes are not yet supported because they require the support
of an IEP, which will be added later.
Advanced features like switch-dev and timestamping will be added later.

This is the v13 of the patch series [v1]. This version of the patchset
addresses comments made on v12.

There series doesn't have any dependency.

Changes from v12 to v13 :
*) Rebased the series on latest net-next.
*) Addressed Jakub's comments on ndo_xmit API. Now we will only stop queues
   based on occupancy not on dma errors.
*) Removed limiting the number of serviced packets to budget for Tx NAPI.
   Now Tx NAPI will keep servicing packets.
*) Removed netif_running() check when packet arrives.
*) Introduced prototypes of APIs in the same patch where these APIs are added.
   Dropped __maybe_unused tags as compiler only cares about prototypes
   existing, not whether actual callers are in place. Now prototypes of these
   APIs are present in the same patch where they are introduced but thes APIs
   are called later (in patch 6).

Changes from v11 to v12 :
*) Rebased the series on latest net-next.
*) Addressed Jakub's comments on ndo_xmit API.
*) Added hooks to .get_rmon_stats for the driver. Now tx / rx bucket size
   and frame counts per bucket will be fetched by ethtool_rmon_stats instead
   of ethtool -S.
*) Added __maybe_unused tags to unused config and classifier APIs in patch
   2,3 and 4. These tags are later removed in patch 6.

Changes from v10 to v11 :
*) Rebased the series on latest net-next.
*) Split the ICSSG driver introduction patch into 9 different patches as
   asked by Jakub.
*) Introduced new patch(patch 8/10) to dump Standard network interface
   staticstics via ndo_get_stats64. Now certain stats that are reported by
   ICSSG hardware and are also part of struct rtnl_link_stats64, will be
   reported by ndo_get_stats64. While other stats that are not part of the
   struct rtnl_link_stats64 will be reported by ethtool -S. These stats
   are not duplicated.

Changes from v9 to v10 :
*) Rebased the series on latest net-next.
*) Moved 'ndev prueth->emac[mac] == emac' assignment to the end of function
   prueth_netdev_init().
*) In unsupported phy_mode switch case instead of returning -EINVAL, store
   the error code in ret and 'goto free'

Changes from v8 to v9 :
*) Rebased the series on latest net-next.
*) Fixed smatch and sparse warnings as pointed by Simon.
*) Fixed leaky ndev in prueth_netdev_init() as asked by Simon.

Changes from v7 to v8 :
*) Rebased the series on 6.5-rc1.
*) Fixed few formattings.

Changes from v6 to v7 :
*) Added RB tag of Rob in patch 1 of this series.
*) Addressed Simon's comment on patch 2 of the series.
*) Rebased patchset on next-20230428 linux-next.

Changes from v5 to v6 :
*) Added RB tag of Andrew Lunn in patch 2 of this series.
*) Addressed Rob's comment on patch 1 of the series.
*) Rebased patchset on next-20230421 linux-next.

Changes from v4 to v5 :
*) Re-arranged properties section in ti,icssg-prueth.yaml file.
*) Added requirement for minimum one ethernet port.
*) Fixed some minor formatting errors as asked by Krzysztof.
*) Dropped SGMII mode from enum mii_mode as SGMII mode is not currently
   supported by the driver.
*) Added switch-case block to handle different phy modes by ICSSG driver.

Changes from v3 to v4 :
*) Addressed Krzysztof's comments and fixed dt_binding_check errors in
   patch 1/2.
*) Added interrupt-extended property in ethernet-ports properties section.
*) Fixed comments in file icssg_switch_map.h according to the Linux coding
   style in patch 2/2. Added Documentation of structures in patch 2/2.

Changes from v2 to v3 :
*) Addressed Rob and Krzysztof's comments on patch 1 of this series.
   Fixed indentation. Removed description and pinctrl section from
   ti,icssg-prueth.yaml file.
*) Addressed Krzysztof, Paolo, Randy, Andrew and Christophe's comments on
   patch 2 of this seires.
*) Fixed blanklines in Kconfig and Makefile. Changed structures to const
   as suggested by Krzysztof.
*) Fixed while loop logic in emac_tx_complete_packets() API as suggested
   by Paolo. Previously in the loop's last iteration 'budget' was 0 and
   napi_consume_skb would wrongly assume the caller is not in NAPI context
   Now, budget won't be zero in last iteration of loop.
*) Removed inline functions addr_to_da1() and addr_to_da0() as asked by
   Andrew.
*) Added dev_err_probe() instead of dev_err() as suggested by Christophe.
*) In ti,icssg-prueth.yaml file, in the patternProperties section of
   ethernet-ports, kept the port name as "port" instead of "ethernet-port"
   as all other drivers were using "port". Will change it if is compulsory
   to use "ethernet-port".

c1e10d5dc7 net: ti: icssg-prueth: Add ICSSG Stats
Add icssg_stats.c to help dump, icssg related driver statistics.

ICSSG has hardware registers for providing statistics like total rx bytes,
total tx bytes, etc. These registers are of 32 bits and hence in case of 1G
link, they overflows in around 32 seconds. The behaviour of these registers
is such that they don't roll back to 0 after overflow but rather stay at
UINT_MAX.

These registers support a feature where the value written to them is
subtracted from the register. This feature can be utilized to fix the
overflowing of stats.

This solution uses a Workqueues based solution where a function gets
called before the registers overflow (every 25 seconds in 1G link, 25000
seconds in 100M link), this function saves the register
values in local variables and writes the last read value to the
register. So any update during the read will be taken care of.

128d5874c0 net: ti: icssg-prueth: Add ICSSG ethernet driver
This is the Ethernet driver for TI AM654 Silicon rev. 2
with the ICSSG PRU Sub-system running dual-EMAC firmware.

The Programmable Real-time Unit and Industrial Communication Subsystem
Gigabit (PRU_ICSSG) is a low-latency microcontroller subsystem in the TI
SoCs. This subsystem is provided for the use cases like implementation of
custom peripheral interfaces, offloading of tasks from the other
processor cores of the SoC, etc.

Every ICSSG core has two Programmable Real-Time Unit(PRUs),
two auxiliary Real-Time Transfer Unit (RT_PRUs), and
two Transmit Real-Time Transfer Units (TX_PRUs). Each one of these runs
its own firmware. Every ICSSG core has two MII ports connect to these
PRUs and also a MDIO port.

The cores can run different firmwares to support different protocols and
features like switch-dev, timestamping, etc.

It uses System DMA to transfer and receive packets and
shared memory register emulation between the firmware and
driver for control and configuration.

This patch adds support for basic EMAC functionality with 1Gbps
and 100Mbps link speed. 10M and half duplex mode are not supported
currently as they require IEP, the support for which will be added later.
Support for switch-dev, timestamp, etc. will be added later
by subsequent patch series.

a2e87e9ef8 drm/msm/dpu: use MDSS data for programming SSPP
Switch to using data from MDSS driver to program the SSPP fetch and UBWC
configuration. As a side-effect, this also swithes the DPU driver from
DPU_HW_UBWC_VER_xx values to the UBWC_x_y enum, which reflects
the hardware register values.
