2021-12-26hwmon: add driver for NZXT RGB&Fan Controller/Smart Device v2.Aleksandr Mezin
This driver implements monitoring and control of fans plugged into the device. Besides typical speed monitoring and PWM duty cycle control, voltage and current are reported for every fan. The device also has 2 connectors for RGB LEDs, support for them isn't implemented (mainly because there is no standardized sysfs interface). Also, the device has a noise sensor, but the sensor seems to be completely useless (and very imprecise), so support for it isn't implemented too. The driver coexists with userspace tools that access the device through hidraw interface with no known issues. The driver has been tested on x86_64, built in and as a module. Some changes/improvements were suggested by Jonas Malaco.

2021-12-26hwmon: (dell-smm) Unify i8k_ioctl() and i8k_ioctl_unlocked()Armin Wolf
The only purpose of i8k_ioctl() is to call i8k_ioctl_unlocked() with i8k_mutex held. Judging from the hwmon code, this mutex only needs to be held when setting the fan speed/mode, so the operation of I8K_SET_FAN is guaranteed to be atomic. Unify both functions and reduce the locking of i8k_mutex to I8K_SET_FAN. Tested on a Dell Inspiron 3505.

2021-12-26hwmon: (dell-smm) Simplify ioctl handlerArmin Wolf
The second switch-case has no real purpose: - for I8K_BIOS_VERSION, val does not represent a return value, making the check for error values unnecessary. - for I8K_MACHINE_ID, val remains zero, so the error check is unnecessary too. Remove the switch-case and move the calls to copy_to_user() into the first switch-case for I8K_BIOS_VERSION/_MACHINE_ID. Omit buff[] since data->bios_machineid already contains the string with the necessary zero padding through devm_kzalloc(). Tested on a Dell Inspiron 3505.

2021-12-26hwmon: (ntc_thermistor) Switch to generic firmware propsLinus Walleij
This switches to retrieveing the configuration of the NTC from generic firmware properties so that we get neutral from device tree: now ACPI or, more importantly, software nodes can be used to spawn NTC devices provided they have the required properties. This was inspired by the similar changes made to the IIO drivers. This was tested on the Ux500 HREF with the NTC devices probing from device tree just as fine after this as before.

2021-12-26hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.Denis Pauk
Linux HWMON sensors driver for ASUS motherboards to read sensors from the embedded controller. Many ASUS motherboards do not publish all the available sensors via the Super I/O chip but the missing ones are available through the embedded controller (EC) registers. This driver implements reading those sensor data via the WMI method BREC, which is known to be present in all ASUS motherboards based on the AMD 500 series chipsets (and probably is available in other models too). The driver needs to know exact register addresses for the sensors and thus support for each motherboard has to be added explicitly. The EC registers do not provide critical values for the sensors and as such they are not published to the HWMON.

Hulk Robot reported a panic in put_page_testzero() when testing madvise() with MADV_SOFT_OFFLINE. The BUG() is triggered when retrying get_any_page(). This is because we keep MF_COUNT_INCREASED flag in second try but the refcnt is not increased. page dumped because: VM_BUG_ON_PAGE(page_ref_count(page) == 0) ------------[ cut here ]------------ kernel BUG at include/linux/mm.h:737! invalid opcode: 0000 [#1] PREEMPT SMP CPU: 5 PID: 2135 Comm: sshd Tainted: G B 5.16.0-rc6-dirty #373 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 RIP: release_pages+0x53f/0x840 Call Trace: free_pages_and_swap_cache+0x64/0x80 tlb_flush_mmu+0x6f/0x220 unmap_page_range+0xe6c/0x12c0 unmap_single_vma+0x90/0x170 unmap_vmas+0xc4/0x180 exit_mmap+0xde/0x3a0 mmput+0xa3/0x250 do_exit+0x564/0x1470 do_group_exit+0x3b/0x100 __do_sys_exit_group+0x13/0x20 __x64_sys_exit_group+0x16/0x20 do_syscall_64+0x34/0x80 entry_SYSCALL_64_after_hwframe+0x44/0xae Modules linked in: ---[ end trace e99579b570fe0649 ]--- RIP: 0010:release_pages+0x53f/0x840 Link: https://lkml.kernel.org/r/20211221074908.3910286-1-liushixin2@huawei.com Fixes: b94e02822deb ("mm,hwpoison: try to narrow window race for free pages") Signed-off-by: Liu Shixin <liushixin2@huawei.com> Reported-by: Hulk Robot <hulkci@huawei.com> Reviewed-by: Oscar Salvador <osalvador@suse.de> Acked-by: Naoya Horiguchi <naoya.horiguchi@nec.com> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
