2023-02-06pinctrl: qcom: sm8450-lpass-lpi: correct swr_rx_data groupKrzysztof Kozlowski
According to hardware programming guide, the swr_rx_data pin group has only two pins (GPIO5 and GPIO6). This is also visible in "struct sm8450_groups" in the driver - GPIO15 does not have swr_rx_data function.

2023-02-06ARM: defconfig: Add IOSCHED_BFQ to the default configsLinus Walleij
ARM systems are often memory constrained and more often than not use slow single-channel storage such as flash memory or MMC/SD-cards. For any interactive systems (such as mobile phones, tablets, chromebooks...) the BFQ I/O scheduler will be desireable. Make sure the BFQ I/O scheduler is available on these systems. Loongarch, MIPS, m68k, UM and S390 has also enabled BFQ in their defconfigs, cf commit b495dfed706c4c5873c0dab8930ad6eb1d276a6c "um: Cleanup CONFIG_IOSCHED_CFQ" where the motivation is that it replaces the former CFQ scheduler.

2023-02-06s390/boot: fix mem_detect extended area allocationVasily Gorbik
Allocation of mem_detect extended area was not considered neither in commit 9641b8cc733f ("s390/ipl: read IPL report at early boot") nor in commit b2d24b97b2a9 ("s390/kernel: add support for kernel address space layout randomization (KASLR)"). As a result mem_detect extended theoretically may overlap with ipl report or randomized kernel image position. But as mem_detect code will allocate extended area only upon exceeding 255 online regions (which should alternate with offline memory regions) it is not seen in practice. To make sure mem_detect extended area does not overlap with ipl report or randomized kernel position extend usage of "safe_addr". Make initrd handling and mem_detect extended area allocation code move it further right and make KASLR takes in into consideration as well.

2023-02-06neigh: make sure used and confirmed times are validJulian Anastasov
Entries can linger in cache without timer for days, thanks to the gc_thresh1 limit. As result, without traffic, the confirmed time can be outdated and to appear to be in the future. Later, on traffic, NUD_STALE entries can switch to NUD_DELAY and start the timer which can see the invalid confirmed time and wrongly switch to NUD_REACHABLE state instead of NUD_PROBE. As result, timer is set many days in the future. This is more visible on 32-bit platforms, with higher HZ value. Why this is a problem? While we expect unused entries to expire, such entries stay in REACHABLE state for too long, locked in cache. They are not expired normally, only when cache is full. Problem and the wrong state change reported by Zhang Changzhong: 172.16.1.18 dev bond0 lladdr 0a:0e:0f:01:12:01 ref 1 used 350521/15994171/350520 probes 4 REACHABLE 350520 seconds have elapsed since this entry was last updated, but it is still in the REACHABLE state (base_reachable_time_ms is 30000), preventing lladdr from being updated through probe. Fix it by ensuring timer is started with valid used/confirmed times. Considering the valid time range is LONG_MAX jiffies, we try not to go too much in the past while we are in DELAY/PROBE state. There are also places that need used/updated times to be validated while timer is not running.

2023-02-06ALSA: hda/realtek: Enable mute/micmute LEDs on HP Elitebook, 645 G9Elvis Angelaccio
The HP Elitebook 645 G9 laptop (with motherboard model 89D2) uses the ALC236 codec and requires the alc236_fixup_hp_mute_led_micmute_vref fixup in order to enable mute/micmute LEDs. Note: the alc236_fixup_hp_gpio_led fixup, which is used by the Elitebook 640 G9, does not work with the 645 G9.

2023-02-06cpufreq: qcom-hw: Fix cpufreq_driver->get() for non-LMH systemsDouglas Anderson
On a sc7180-based Chromebook, when I go to /sys/devices/system/cpu/cpu0/cpufreq I can see: cpuinfo_cur_freq:2995200 cpuinfo_max_freq:1804800 scaling_available_frequencies:300000 576000 ... 1708800 1804800 scaling_cur_freq:1804800 scaling_max_freq:1804800 As you can see the `cpuinfo_cur_freq` is bogus. It turns out that this bogus info started showing up as of commit c72cf0cb1d77 ("cpufreq: qcom-hw: Fix the frequency returned by cpufreq_driver->get()"). That commit seems to assume that everyone is on the LMH bandwagon, but sc7180 isn't. Let's go back to the old code in the case where LMH isn't used.
