         - Finally get the task_work_add() cleanup done properly, so we don't

       "A small selection of further arm64 fixes and updates. Most of these
        are fixes that came in during the merge window, with the exception of
        the HAVE_MOVE_PMD mremap() speed-up which we discussed back in 2018
        and somehow forgot to enable upstream.
      
         - Improve performance of Spectre-v2 mitigation on Falkor CPUs (if
           you're lucky enough to have one)
      
         - Select HAVE_MOVE_PMD. This has been shown to improve mremap()
           performance, which is used heavily by the Android runtime GC, and
           it seems we forgot to enable this upstream back in 2018.
      
         - Ensure linker flags are consistent between LLVM and BFD
      
         - Fix stale comment in Spectre mitigation rework
      
         - Fix broken copyright header
      
         - Fix KASLR randomisation of the linear map

      Linus Torvalds authored
      Pull clk updates from Stephen Boyd:
       "This contains no changes to the core framework. It is a collection of
        various clk driver updates.
      
        The biggest driver updates in terms of lines of code is the Allwinner
        driver, closely followed by the Qualcomm and Mediatek drivers. All of
        those hit high because we add so many lines of clk data. Coming in
        fourth place is i.MX which also adds a bunch of clk data. This
        accounts for the new driver additions this time around.
      
        Otherwise the patches are lots of little cleanups and fixes for
        various clk drivers that have baked in linux-next for a while. I
        suppose one highlight or theme is that more clk drivers are being
        updated to work as modules, which is interesting to see such critical
        SoC infrastructure work as a loadable module.
      
        New Drivers:
         - Support qcom SM8150/SM8250 video and display clks
         - Support Mediatek MT8167 clks
         - Add clock for CRC block found on vf610 SoCs
         - Add support for the Renesas R-Car V3U (R8A779A0) SoC
         - Add support for the VSP for Resizing clock on Renesas RZ/G1H
         - Support Allwinner A100 SoC clks
      
        Removed Drivers:
         - Remove i.MX21 clock driver, as i.MX21 platform support is being
           dropped
      
        Updates:
         - Change how qcom's display port clks work
         - Small non-critical fixes for TI clk driver
         - Remove various unused variables in clk drivers
         - Allow Rockchip clk driver to be a module
         - Remove most __clk_lookup() calls in Samsung drivers (yay!)
         - Support building i.MX ARMv8 platforms clock driver as module
         - Some kerneldoc fixes here and there
         - A couple of minor i.MX clk data corrections
         - Update audio clock inverter and fdiv2 flag on Amlogic g12
         - Make amlogic clk drivers configurable in Kconfig
         - Fix Renesas VSP clock names to match corrected hardware
           documentation
         - Sigma-delta modulation on Allwinner R40
         - Various fixes for at91 clk driver

      ARC: perf: redo the pct irq missing in device-tree handling · 8c42a5c0
      Vineet Gupta authored
      commit feb92d7d "(ARC: perf: don't bail setup if pct irq
      missing in device-tree)" introduced a silly brown-paper bag bug:
      The assignment and comparison in an if statement were not bracketed
      correctly leaving the order of evaluation undefined.
      
      |
      | if (has_interrupts && (irq = platform_get_irq(pdev, 0) >= 0)) {
      |                           ^^^                         ^^^^
      
      And given such a chance, the compiler will bite you hard, fully entitled
      to generating this piece of beauty:
      
      |
      | # if (has_interrupts && (irq = platform_get_irq(pdev, 0) >= 0)) {
      |
      | bl.d @platform_get_irq  <-- irq returned in r0
      |
      | setge r2, r0, 0   	<-- r2 is bool 1 or 0 if irq >= 0 true/false
      | brlt.d r0, 0, @.L114
      |
      | st_s	r2,[sp]    	<-- irq saved is bool 1 or 0, not actual return val
      | st	1,[r3,160]   	# arc_pmu.18_29->irq <-- drops bool and assumes 1
      |
      | # return __request_percpu_irq(irq, handler, 0,
      |
      | bl.d @__request_percpu_irq;
      | mov_s	r0,1	   <-- drops even bool and assumes 1 which fails
      
      With the snafu fixed, everything is as expected.
      
      | bl.d @platform_get_irq	<-- returns irq in r0
      |
      | mov_s	r2,r0
      | brlt.d r2, 0, @.L112
      |
      | st_s	r0,[sp]			<-- irq isaved is actual return value above
      | st	r0,[r13,160]	#arc_pmu.18_27->irq
      |
      | bl.d @__request_percpu_irq	<-- r0 unchanged so actual irq returned

        In addition, thanks to Mauricio for fixing a race where mmap'ed pages

        commit could result in bad checksums in the failure that could cause
        journal replays to fail.
      
        Also notable is Ritesh's buffered write optimization which can result
        in significant improvements on parallel write workloads. (The kernel

      ext4: fix invalid inode checksum · 13221811
      Luo Meng authored
      During the stability test, there are some errors:
        ext4_lookup:1590: inode #6967: comm fsstress: iget: checksum invalid.
      
      If the inode->i_iblocks too big and doesn't set huge file flag, checksum
      will not be recalculated when update the inode information to it's buffer.
      If other inode marks the buffer dirty, then the inconsistent inode will
      be flushed to disk.
      
      Fix this problem by checking i_blocks in advance.

      ext4: fast commit recovery path · 8016e29f
      Harshad Shirwadkar authored
      This patch adds fast commit recovery path support for Ext4 file
      system. We add several helper functions that are similar in spirit to
      e2fsprogs journal recovery path handlers. Example of such functions
      include - a simple block allocator, idempotent block bitmap update
      function etc. Using these routines and the fast commit log in the fast
      commit area, the recovery path (ext4_fc_replay()) performs fast commit
      log recovery.

      ext4: main fast-commit commit path · aa75f4d3
      Harshad Shirwadkar authored
      This patch adds main fast commit commit path handlers. The overall
      patch can be divided into two inter-related parts:
      
      (A) Metadata updates tracking
      
          This part consists of helper functions to track changes that need
          to be committed during a commit operation. These updates are
          maintained by Ext4 in different in-memory queues. Following are
          the APIs and their short description that are implemented in this
          patch:
      
          - ext4_fc_track_link/unlink/creat() - Track unlink. link and creat
            operations
          - ext4_fc_track_range() - Track changed logical block offsets
            inodes
          - ext4_fc_track_inode() - Track inodes
          - ext4_fc_mark_ineligible() - Mark file system fast commit
            ineligible()
          - ext4_fc_start_update() / ext4_fc_stop_update() /
            ext4_fc_start_ineligible() / ext4_fc_stop_ineligible() These
            functions are useful for co-ordinating inode updates with
            commits.
      
      (B) Main commit Path
      
          This part consists of functions to convert updates tracked in
          in-memory data structures into on-disk commits. Function
          ext4_fc_commit() is the main entry point to commit path.

      ext4 / jbd2: add fast commit initialization · 6866d7b3
      Harshad Shirwadkar authored
      This patch adds fast commit area trackers in the journal_t
      structure. These are initialized via the jbd2_fc_init() routine that
      this patch adds. This patch also adds ext4/fast_commit.c and
      ext4/fast_commit.h files for fast commit code that will be added in
      subsequent patches in this series.

      We are running out of mount option bits. Add handling for using
      s_mount_opt2. Add ext4 and jbd2 fast commit feature flag and also add
      ability to turn off the fast commit feature in Ext4.
