2021-04-19btrfs: fix comment for btrfs ordered extent flag bitsQu Wenruo
There is small error in comment about BTRFS_ORDERED_* flags, added in commit 3c198fe06449 ("btrfs: rework the order of btrfs_ordered_extent::flags") but the fixup did not get merged in time. The 4 types are for ordered extent itself, not for direct io. Only 3 types support direct io, REGULAR/NOCOW/PREALLOC. Fix the comment to reflect that.

Since kernel v5.1, fanotify_init(2) supports the flag FAN_REPORT_FID for identifying objects using file handle and fsid in events. fanotify_mark(2) fails with -ENODEV when trying to set a mark on filesystems that report null f_fsid in stasfs(2). Use the digest of uuid as f_fsid for tmpfs to uniquely identify tmpfs objects as best as possible and allow setting an fanotify mark that reports events with file handles on tmpfs.

2021-04-19spi: sync up initial chipselect stateDavid Bauer
When initially probing the SPI slave device, the call for disabling an SPI device without the SPI_CS_HIGH flag is not applied, as the condition for checking whether or not the state to be applied equals the one currently set evaluates to true. This however might not necessarily be the case, as the chipselect might be active. Add a force flag to spi_set_cs which allows to override this early exit condition. Set it to false everywhere except when called from spi_setup to sync up the initial CS state.

In order to optimize accesses to spi flashes, trigger a DMA only if more than 4 bytes has to be transferred. DMA transfer preparation's cost becomes negligible above 4 bytes to transfer. Below this threshold, indirect transfer give more throughput. mtd_speedtest shows that page write throughtput increases : - from 779 to 853 KiB/s (~9.5%) with s25fl512s SPI-NOR. - from 5283 to 5666 KiB/s (~7.25%) with Micron SPI-NAND.

2021-04-19xfrm: ipcomp: remove unnecessary get_cpu()Sabrina Dubroca
While testing ipcomp on a realtime kernel, Xiumei reported a "sleeping in atomic" bug, caused by a memory allocation while preemption is disabled (ipcomp_decompress -> alloc_page -> ... get_page_from_freelist). As Sebastian noted [1], this get_cpu() isn't actually needed, since ipcomp_decompress() is called in napi context anyway, so BH is already disabled. This patch replaces get_cpu + per_cpu_ptr with this_cpu_ptr, then simplifies the error returns, since there isn't any common operation left.

2021-04-19mac80211: make ieee80211_vif_to_wdev work when the vif isn't in the driverEmmanuel Grumbach
This will allow the low level driver to get the wdev during the add_interface flow. In order to do that, remove a few checks from there and do not return NULL for vifs that were not yet added to the driver. Note that all the current callers of this helper function assume that the vif already exists: - The callers from the drivers already have a vif pointer. Before this change, ieee80211_vif_to_wdev would return NULL in some cases, but those callers don't even check they get a non-NULL pointer from ieee80211_vif_to_wdev. - The callers from net/mac80211/cfg.c assume the vif is already added to the driver as well. So, this change has no impact on existing callers of this helper function.

2021-04-19mac80211: properly process TXQ management framesJohannes Berg
My previous commit to not apply flow control to management frames that are going over TXQs (which is currently only the case for iwlwifi, I think) broke things, with iwlwifi firmware crashing on certain frames. As it turns out, that was due to the frame being too short: space for the MIC wasn't added at the end of encrypted management frames. Clearly, this is due to using the 'frags' queue - this is meant only for frames that have already been processed for TX, and the code in ieee80211_tx_dequeue() just returns them. This caused all management frames to now not get any TX processing. To fix this, use IEEE80211_TX_INTCFL_NEED_TXPROCESSING (which is currently used only in other circumstances) to indicate that the frames need processing, and clear it immediately after so that, at least in theory, MMPDUs can be fragmented.

Add touchscreen info for the Teclast Tbook 11 tablet. This includes info for getting the firmware directly from the UEFI, so that the user does not need to manually install the firmware in /lib/firmware/silead.

2021-04-19platform/x86: intel_pmc_core: Add option to set/clear LPM modeDavid E. Box
By default the Low Power Mode (LPM or sub-state) status registers will latch condition status on every entry into Package C10. This is configurable in the PMC to allow latching on any achievable sub-state. Add a debugfs file to support this. Also add the option to clear the status registers to 0. Clearing the status registers before testing removes ambiguity around when the current values were set.
