2022-03-23selftests/x86/amx: Update the ARCH_REQ_XCOMP_PERM testChang S. Bae
Update the arch_prctl test to check the permission bitmap whether the requested feature is added as expected or not. Every non-dynamic feature that is enabled is permitted already for use. TILECFG is not dynamic feature. Ensure the bit is always on from ARCH_GET_XCOMP_PERM. Signed-off-by: Chang S.

2022-03-23x86/fpu/xstate: Fix the ARCH_REQ_XCOMP_PERM implementationYang Zhong
ARCH_REQ_XCOMP_PERM is supposed to add the requested feature to the permission bitmap of thread_group_leader()->fpu. But the code overwrites the bitmap with the requested feature bit only rather than adding it. Fix the code to add the requested feature bit to the master bitmask.

2022-03-23cifs: fix incorrect use of list iterator after the loopXiaomeng Tong
The bug is here: if (!tcon) { resched = true; list_del_init(&ses->rlist); cifs_put_smb_ses(ses); Because the list_for_each_entry() never exits early (without any break/goto/return inside the loop), the iterator 'ses' after the loop will always be an pointer to a invalid struct containing the HEAD (&pserver->smb_ses_list). As a result, the uses of 'ses' above will lead to a invalid memory access. The original intention should have been to walk each entry 'ses' in '&tmp_ses_list', delete '&ses->rlist' and put 'ses'. So fix it with a list_for_each_entry_safe().

There is no need to store the fids as le64 integers as they are opaque to the client and only used for equality.

2022-03-23cifs: fix bad fids sent over wirePaulo Alcantara
The client used to partially convert the fids to le64, while storing or sending them by using host endianness. This broke the client on big-endian machines.

2022-03-23MAINTAINERS: remove section LIBNVDIMM BLK: MMIO-APERTURE DRIVERLukas Bulwahn
Commit f8669f1d6a86 ("nvdimm/blk: Delete the block-aperture window driver") removes the file drivers/nvdimm/blk.c, but misses to adjust MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. The section LIBNVDIMM BLK: MMIO-APERTURE DRIVER refers to the driver in blk.c, and some more generic nvdimm code in region_devs.c. As the driver is deleted, delete the section LIBNVDIMM BLK: MMIO-APERTURE DRIVER in MAINTAINERS as well. The remaining file region_devs.c is still covered by the section LIBNVDIMM: NON-VOLATILE MEMORY DEVICE SUBSYSTEM, and all patches to region_devs.c will still reach the same developers as before.

2022-03-23rtc: ds1685: switch to RTC_FEATURE_UPDATE_INTERRUPTAlexandre Belloni
Stop using uie_unsupported and clear RTC_FEATURE_UPDATE_INTERRUPT instead. There is currently a missing information as to why this is not supported on ioc3.

2022-03-23clk: sunxi-ng: sun6i-rtc: Add support for H6Samuel Holland
H6 supports IOSC calibration and an ext-osc32k input. Unlike newer SoCs, it has a single parent for its fanout clock. Add support for H6 in the CCU driver, replacing the support in the existing early OF clock provider.

2022-03-23clk: sunxi-ng: Add support for the sun6i RTC clocksSamuel Holland
The RTC power domain in sun6i and newer SoCs manages the 16 MHz RC oscillator (called "IOSC" or "osc16M") and the optional 32 kHz crystal oscillator (called "LOSC" or "osc32k"). Starting with the H6, this power domain also handles the 24 MHz DCXO (called variously "HOSC", "dcxo24M", or "osc24M") as well. The H6 also adds a calibration circuit for IOSC. Later SoCs introduce further variations on the design: - H616 adds an additional mux for the 32 kHz fanout source. - R329 adds an additional mux for the RTC timekeeping clock, a clock for the SPI bus between power domains inside the RTC, and removes the IOSC calibration functionality. Take advantage of the CCU framework to handle this increased complexity. This driver is intended to be a drop-in replacement for the existing RTC clock provider. So some runtime adjustment of the clock parents is needed, both to handle hardware differences, and to support the old binding which omitted some of the input clocks.

2022-03-23clk: sunxi-ng: mux: Allow muxes to have keysSamuel Holland
The muxes in the RTC can only be updated when setting a key field to a specific value. Add a feature flag to denote muxes with this property. Since so far the key value is always the same, it does not need to be provided separately for each mux.

2022-03-23rtc: wm8350: Handle error for wm8350_register_irqJiasheng Jiang
As the potential failure of the wm8350_register_irq(), it should be better to check it and return error if fails. Also, it need not free 'wm_rtc->rtc' since it will be freed automatically.

2022-03-23rtc: sun6i: Add Allwinner H616 supportAndre Przywara
The H616 RTC changes its day storage to the newly introduced linear day scheme, so pair the new compatible string with this feature flag. The RTC clock parts are handled in a separate driver now, so we skip the clock parts in this driver completely.

2022-03-23rtc: sun6i: Add support for broken-down alarm registersAndre Przywara
Newer versions of the Allwinner RTC, for instance as found in the H616 SoC, not only store the current day as a linear number, but also change the way the alarm is handled: There are now two registers, that explicitly store the wakeup time, in the same format as the current time. Add support for that variant by writing the requested wakeup time directly into the registers, instead of programming the seconds left, as the old SoCs required.
