      Pull s390 fixes from Heiko Carstens:
      
       - fix stack unwinder: the stack unwinder rework has on off-by-one bug
         which prevents following stack backchains over more than one context
         (e.g. irq -> process).
      
       - fix address space detection in exception handler: if user space
         switches to access register mode, which is not supported anymore, the
         exception handler may resolve to the wrong address space.

      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.

      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.

      Some chipsets will be switching to updated SEC2 LS firmware, so we need to
      plumb that through.

      It's not enough to have per-falcon structures anymore, we have multiple
      versions of some firmware now that have interface differences.

      Will be passed to the FW loader function as an upper bound on the supported
      FW version to attempt to load.

      We have a need for this now with updated SEC2 LS FW images that have an
      incompatible interface from the previous version.
