      Pull MIPS fixes from Paul Burton:
      
       - Declare ginvt() __always_inline due to its use of an argument as an
         inline asm immediate.
      
       - A VDSO build fix following Kbuild changes made this cycle.
      
       - A fix for boot failures on txx9 systems following memory
         initialization changes made this cycle.
      
       - Bounds check virt_addr_valid() to prevent it spuriously indicating
         that bogus addresses are valid, in turn fixing hardened usercopy
         failures that have been present since v4.12.
      
       - Build uImage.gz for pistachio systems by default, since this is the
         image we need in order to actually boot on a board.
      
       - Remove an unused variable in our uprobes code.

       "Another round of SPDX header file fixes for 5.2-rc4
      
        These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
        added, based on the text in the files. We are slowly chipping away at
        the 700+ different ways people tried to write the license text. All of
        these were reviewed on the spdx mailing list by a number of different
        people.
      
        We now have over 60% of the kernel files covered with SPDX tags:
      	$ ./scripts/spdxcheck.py -v 2>&1 | grep Files
      	Files checked:            64533
      	Files with SPDX:          40392
      	Files with errors:            0
      
        I think the majority of the "easy" fixups are now done, it's now the
        start of the longer-tail of crazy variants to wade through"

      i2c: xiic: Add max_read_len quirk · 49b80958
      Robert Hancock authored
      This driver does not support reading more than 255 bytes at once because
      the register for storing the number of bytes to read is only 8 bits. Add
      a max_read_len quirk to enforce this.
      
      This was found when using this driver with the SFP driver, which was
      previously reading all 256 bytes in the SFP EEPROM in one transaction.
      This caused a bunch of hard-to-debug errors in the xiic driver since the
      driver/logic was treating the number of bytes to read as zero.
      Rejecting transactions that aren't supported at least allows the problem
      to be diagnosed more easily.

      lockref: Limit number of cmpxchg loop retries · 893a7d32
      Jan Glauber authored
      The lockref cmpxchg loop is unbound as long as the spinlock is not
      taken. Depending on the hardware implementation of compare-and-swap
      a high number of loop retries might happen.
      
      Add an upper bound to the loop to force the fallback to spinlocks
      after some time. A retry value of 100 should not impact any hardware
      that does not have this issue.
      
      With the retry limit the performance of an open-close testcase
      improved between 60-70% on ThunderX2.

      uaccess: add noop untagged_addr definition · d9344522
      Andrey Konovalov authored
      Architectures that support memory tagging have a need to perform untagging
      (stripping the tag) in various parts of the kernel. This patch adds an
      untagged_addr() macro, which is defined as noop for architectures that do
      not support memory tagging. The oncoming patch series will define it at
      least for sparc64 and arm64.

      kbuild: use more portable 'command -v' for cc-cross-prefix · 913ab978
      Masahiro Yamada authored
      To print the pathname that will be used by shell in the current
      environment, 'command -v' is a standardized way. [1]
      
      'which' is also often used in scripts, but it is less portable.
      
      When I worked on commit bd55f96f ("kbuild: refactor cc-cross-prefix
      implementation"), I was eager to use 'command -v' but it did not work.
      (The reason is explained below.)
      
      I kept 'which' as before but got rid of '> /dev/null 2>&1' as I
      thought it was no longer needed. Sorry, I was wrong.
      
      It works well on my Ubuntu machine, but Alexey Brodkin reports noisy
      warnings on CentOS7 when 'which' fails to find the given command in
      the PATH environment.
      
        $ which foo
        which: no foo in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)
      
      Given that behavior of 'which' depends on system (and it may not be
      installed by default), I want to try 'command -v' once again.
      
      The specification [1] clearly describes the behavior of 'command -v'
      when the given command is not found:
      
        Otherwise, no output shall be written and the exit status shall reflect
        that the name was not found.
      
      However, we need a little magic to use 'command -v' from Make.
      
      $(shell ...) passes the argument to a subshell for execution, and
      returns the standard output of the command.
      
      Here is a trick. GNU Make may optimize this by executing the command
      directly instead of forking a subshell, if no shell special characters
      are found in the command and omitting the subshell will not change the
      behavior.
      
      In this case, no shell special character is used. So, Make will try
      to run it directly. However, 'command' is a shell-builtin command,
      then Make would fail to find it in the PATH environment:
      
        $ make ARCH=m68k defconfig
        make: command: Command not found
        make: command: Command not found
        make: command: Command not found
      
      In fact, Make has a table of shell-builtin commands because it must
      ask the shell to execute them.
      
      Until recently, 'command' was missing in the table.
      
      This issue was fixed by the following commit:
      
      | commit 1af314465e5dfe3e8baa839a32a72e83c04f26ef
      | Author: Paul Smith <psmith@gnu.org>
      | Date:   Sun Nov 12 18:10:28 2017 -0500
      |
      |     * job.c: Add "command" as a known shell built-in.
      |
      |     This is not a POSIX shell built-in but it's common in UNIX shells.
      |     Reported by Nick Bowler <nbowler@draconx.ca>.
      
      Because the latest release is GNU Make 4.2.1 in 2016, this commit is
      not included in any released versions. (But some distributions may
      have back-ported it.)
      
      We need to trick Make to spawn a subshell. There are various ways to
      do so:
      
       1) Use a shell special character '~' as dummy
      
          $(shell : ~; command -v $(c)gcc)
      
       2) Use a variable reference that always expands to the empty string
          (suggested by David Laight)
      
          $(shell command$${x:+} -v $(c)gcc)
      
       3) Use redirect
      
          $(shell command -v $(c)gcc 2>/dev/null)
      
      I chose 3) to not confuse people. The stderr would not be polluted
      anyway, but it will provide extra safety, and is easy to understand.
      
      Tested on Make 3.81, 3.82, 4.0, 4.1, 4.2, 4.2.1

      block, bfq: add weight symlink to the bfq.weight cgroup parameter · 19e9da9e
      Angelo Ruocco authored
      Many userspace tools and services use the proportional-share policy of
      the blkio/io cgroups controller. The CFQ I/O scheduler implemented
      this policy for the legacy block layer. To modify the weight of a
      group in case CFQ was in charge, the 'weight' parameter of the group
      must be modified. On the other hand, the BFQ I/O scheduler implements
      the same policy in blk-mq, but, with BFQ, the parameter to modify has
      a different name: bfq.weight (forced choice until legacy block was
      present, because two different policies cannot share a common parameter
      in cgroups).
      
      Due to CFQ legacy, most if not all userspace configurations still use
      the parameter 'weight', and for the moment do not seem likely to be
      changed. But, when CFQ went away with legacy block, such a parameter
      ceased to exist.
      
      So, a simple workaround has been proposed [1] to make all
      configurations work: add a symlink, named weight, to bfq.weight. This
      commit adds such a symlink.

      drm/nouveau/secboot/gp10[2467]: support newer FW to fix SEC2 failures on some boards · ab4bec16
      Ben Skeggs authored
      Some newer boards with these chipsets aren't compatible with the prior
      version of the SEC2 FW, and fail to load as a result.
      
      This newer FW is actually the one we already use on >=GP108.
      
      Unfortunately, there are interface differences in GP108's FW, making it
      impossible to simply move files around in linux-firmware to solve this.
      
      We need to be able to keep compatibility with all linux-firmware/kernel
      combinations, which means supporting both firmwares.

      block: free sched's request pool in blk_cleanup_queue · c3e22192
      Ming Lei authored
      In theory, IO scheduler belongs to request queue, and the request pool
      of sched tags belongs to the request queue too.
      
      However, the current tags allocation interfaces are re-used for both
      driver tags and sched tags, and driver tags is definitely host wide,
      and doesn't belong to any request queue, same with its request pool.
      So we need tagset instance for freeing request of sched tags.
      
      Meantime, blk_mq_free_tag_set() often follows blk_cleanup_queue() in case
      of non-BLK_MQ_F_TAG_SHARED, this way requires that request pool of sched
      tags to be freed before calling blk_mq_free_tag_set().
      
      Commit 47cdee29 ("block: move blk_exit_queue into __blk_release_queue")
      moves blk_exit_queue into __blk_release_queue for simplying the fast
      path in generic_make_request(), then causes oops during freeing requests
      of sched tags in __blk_release_queue().
      
      Fix the above issue by move freeing request pool of sched tags into
      blk_cleanup_queue(), this way is safe becasue queue has been frozen and no any
      in-queue requests at that time. Freeing sched tags has to be kept in queue's
      release handler becasue there might be un-completed dispatch activity
      which might refer to sched tags.
