git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux Pull btrfs fix from David Sterba: "One more patch that we'd like to get to 5.12 before release. It's changing where and how the superblock is stored in the zoned mode. It is an on-disk format change but so far there are no implications for users as the proper mkfs support hasn't been merged and is waiting for the kernel side to settle. Until now, the superblocks were derived from the zone index, but zone size can differ per device. This is changed to be based on fixed offset values, to make it independent of the device zone size. The work on that got a bit delayed, we discussed the exact locations to support potential device sizes and usecases. (Partially delayed also due to my vacation.) Having that in the same release where the zoned mode is declared usable is highly desired, there are userspace projects that need to be updated to recognize the feature. Pushing that to the next release would make things harder to test" * tag 'for-5.12-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: btrfs: zoned: move superblock logging zone location

2021-04-11kasan, arm64: tests supports for HW_TAGS async modeAndrey Konovalov
This change adds KASAN-KUnit tests support for the async HW_TAGS mode. In async mode, tag fault aren't being generated synchronously when a bad access happens, but are instead explicitly checked for by the kernel. As each KASAN-KUnit test expect a fault to happen before the test is over, check for faults as a part of the test handler.

When MTE async mode is enabled TFSR_EL1 contains the accumulative asynchronous tag check faults for EL1 and EL0. During the suspend/resume operations the firmware might perform some operations that could change the state of the register resulting in a spurious tag check fault report. Report asynchronous tag faults before suspend and clear the TFSR_EL1 register after resume to prevent this to happen.

2021-04-11arm64: mte: Enable async tag check faultVincenzo Frascino
MTE provides a mode that asynchronously updates the TFSR_EL1 register when a tag check exception is detected. To take advantage of this mode the kernel has to verify the status of the register at: 1. Context switching 2. Return to user/EL0 (Not required in entry from EL0 since the kernel did not run) 3. Kernel entry from EL1 4. Kernel exit to EL1 If the register is non-zero a trace is reported. Add the required features for EL1 detection and reporting. Note: ITFSB bit is set in the SCTLR_EL1 register hence it guaranties that the indirect writes to TFSR_EL1 are synchronized at exception entry to EL1. On the context switch path the synchronization is guarantied by the dsb() in __switch_to(). The dsb(nsh) in mte_check_tfsr_exit() is provisional pending confirmation by the architects.

2021-04-11arm64: mte: Enable TCO in functions that can read beyond buffer limitsVincenzo Frascino
load_unaligned_zeropad() and __get/put_kernel_nofault() functions can read past some buffer limits which may include some MTE granule with a different tag. When MTE async mode is enabled, the load operation crosses the boundaries and the next granule has a different tag the PE sets the TFSR_EL1.TF1 bit as if an asynchronous tag fault is happened. Enable Tag Check Override (TCO) in these functions before the load and disable it afterwards to prevent this to happen. Note: The same condition can be hit in MTE sync mode but we deal with it through the exception handling. In the current implementation, mte_async_mode flag is set only at boot time but in future kasan might acquire some runtime features that that change the mode dynamically, hence we disable it when sync mode is selected for future proof.

2021-04-11kasan: Add KASAN mode kernel parameterVincenzo Frascino
Architectures supported by KASAN_HW_TAGS can provide a sync or async mode of execution. On an MTE enabled arm64 hw for example this can be identified with the synchronous or asynchronous tagging mode of execution. In synchronous mode, an exception is triggered if a tag check fault occurs. In asynchronous mode, if a tag check fault occurs, the TFSR_EL1 register is updated asynchronously. The kernel checks the corresponding bits periodically. KASAN requires a specific kernel command line parameter to make use of this hw features. Add KASAN HW execution mode kernel command line parameter. Note: This patch adds the kasan.mode kernel parameter and the sync/async kernel command line options to enable the described features.

This reverts commit 04b8edad262eec0d153005973dfbdd83423c0dcb. mx25l51245g and mx66l51235l have the same flash ID. The flash detection returns the first entry in the flash_info array that matches the flash ID that was read, thus for the 0xc2201a ID, mx25l51245g was always hit, introducing a regression for mx66l51235l. If one wants to differentiate the flash names, a better fix would be to differentiate between the two at run-time, depending on SFDP, and choose the correct name from a list of flash names, depending on the SFDP differentiator.

The MHI bus will expose EDL channels (34, 35) and then the opensource QDL tool [1] can be used to flash the firmware from the host. - Added an internal helper for polling the MHI registers with a retry interval. This helper is used now to poll for the MHI ready state in MHI STATUS register. - Various fixes for issues found during the bringup of SDX24/SDX55 based Quectel and Telit modems. - Updates to the Execution environment handling for proper downloading of the AMSS image from SBL (Secondary Bootloader) mode. - Added support for sending STOP channel command to the MHI device and also made changes to the MHI core for proper handling of stop and restart. - Fixed the runtime_pm handling in the core by forcing the device to be in wake mode until TX completion and allowing it to suspend for RX. - Added sanity checks for values read from the device to avoid crash if those are corrupted somehow. - Fixed warnings generated by sparse (W=2) - Couple of kernel doc cleanups in mhi.h pci_generic: - Added support for runtime PM and generic PM - Added Firehose channels for flashing the firmware - Added support for modems such as Quectel EM1XXGR-L, SDX24, SDX65, Foxconn T99W175 exposing relevant channels.

https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next Oded writes: This tag contains habanalabs driver changes for v5.13: - Add support to reset device after the user closes the file descriptor. Because we support a single user, we can reset the device (if needs to) after a user closes its file descriptor to make sure the device is in idle and clean state for the next user. - Add a new feature to allow the user to wait on interrupt. This is needed for future ASICs - Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to support failure of allocating with GFP_ATOMIC. - Update code to support the latest firmware image: - More security features are done in the firmware - Remove hard-coded assumptions and replace them with values that are sent to the firmware on loading. - Print device unusable error - Reset device in case the communication between driver and firmware gets out of sync. - Support new PCI device ids for secured GAUDI. - Expose current power draw through the INFO IOCTL. - Support resetting the device upon a request from the BMC (through F/W). - Always use only a single MSI in GAUDI, due to H/W limitation. - Improve data-path code by taking out code from spinlock protection. - Allow user to specify custom timeout per Command Submission. - Some enhancements to debugfs. - Various minor changes and improvements. * tag 'misc-habanalabs-next-2021-04-10' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (41 commits) habanalabs: print f/w boot unknown error habanalabs: update to latest F/W communication header habanalabs/gaudi: skip iATU if F/W security is enabled habanalabs/gaudi: derive security status from pci id habanalabs: move dram scrub to free sequence habanalabs: send dynamic msi-x indexes to f/w habanalabs/gaudi: clear QM errors only if not in stop_on_err mode habanalabs: support DEVICE_UNUSABLE error indication from FW habanalabs: use strscpy instead of sprintf and strlcpy habanalabs: remove the store jobs array from CS IOCTL habanalabs/gaudi: add debugfs to DMA from the device habanalabs/gaudi: sync stream add protection to SOB reset flow habanalabs: add custom timeout flag per cs habanalabs: improve utilization calculation habanalabs: support legacy and new pll indexes habanalabs: move relevant datapath work outside cs lock habanalabs: avoid soft lockup bug upon mapping error habanalabs/gaudi: Update async events header habanalabs/gaudi: unsecure TPC cfg status registers habanalabs/gaudi: always use single-msi mode ...
