      With this, we finally get to the promised end result:

         stray instances of ->poll() still using those will be caught by

       - eventpoll.c and select.c warning-free wrt __poll_t
      
       - no more kernel-side definitions of POLL... - userland ones are
         visible through the entire kernel (and used pretty much only for
         mangle/demangle)

      vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
      Linus Torvalds 提交于
      This is the mindless scripted replacement of kernel use of POLL*
      variables as described by Al, done by this script:
      
          for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
              L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
              for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
          done
      
      with de-mangling cleanups yet to come.
      
      NOTE! On almost all architectures, the EPOLL* constants have the same
      values as the POLL* constants do.  But they keyword here is "almost".
      For various bad reasons they aren't the same, and epoll() doesn't
      actually work quite correctly in some cases due to this on Sparc et al.
      
      The next patch from Al will sort out the final differences, and we
      should be all done.

      Pull more poll annotation updates from Al Viro:
       "This is preparation to solving the problems you've mentioned in the
        original poll series.
      
        After this series, the kernel is ready for running
      
            for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do

            done
      
        as a for bulk search-and-replace.
      
        After that, the kernel is ready to apply the patch to unify
        {de,}mangle_poll(), and then get rid of kernel-side POLL... uses
        entirely, and we should be all done with that stuff.
      
        Basically, that's what you suggested wrt KPOLL..., except that we can
        use EPOLL... instead - they already are arch-independent (and equal to
        what is currently kernel-side POLL...).
      
        After the preparations (in this series) switch to returning EPOLL...
        from ->poll() instances is completely mechanical and kernel-side
        POLL... can go away. The last step (killing kernel-side POLL... and
        unifying {de,}mangle_poll() has to be done after the
        search-and-replace job, since we need userland-side POLL... for
        unified {de,}mangle_poll(), thus the cherry-pick at the last step.
      
        After that we will have:
      
         - POLL{IN,OUT,...} *not* in __poll_t, so any stray instances of
           ->poll() still using those will be caught by sparse.
      
         - eventpoll.c and select.c warning-free wrt __poll_t
      
         - no more kernel-side definitions of POLL... - userland ones are
           visible through the entire kernel (and used pretty much only for

      Improve the DTS files by removing all the leading "0x" and zeros to fix the

      and
      
      Warning (unit_address_format): Node /XXX unit name should not have leading 0s
      
      Converted using the following command:
      
      find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -E -i -e "s/@0x([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" -e "s/@0+([0-9a-fA-F\.]+)\s?\{/@\L\1 \{/g" {} +
      
      For simplicity, two sed expressions were used to solve each warnings separately.
      
      To make the regex expression more robust a few other issues were resolved,
      namely setting unit-address to lower case, and adding a whitespace before the
      the opening curly brace:

      drm/vc4: Expose performance counters to userspace · 65101d8c

      The V3D engine has various hardware counters which might be interesting
      to userspace performance analysis tools.
      
      Expose new ioctls to create/destroy a performance monitor object and
      query the counter values of this perfmance monitor.
      
      Note that a perfomance monitor is given an ID that is only valid on the
      file descriptor it has been allocated from. A performance monitor can be
      attached to a CL submission and the driver will enable HW counters for
      this request and update the performance monitor values at the end of the
      job.

      drm: Print the pid when debug logging an ioctl error. · 9c950e46
      Eric Anholt 提交于
      When we debug print what ioctl we're calling into, we include the pid.
      If you have multiple processes rendering simulataneously, the error
      return also needs the pid so you can see which of the ioctl calls was
      the one to fail.

      of_irq_parse_and_map_pci(), but neglected to capture the virq
      returned by irq_create_of_mapping(), so virq remained zero, which

         - fix a iscsi-target 4.14+ regression related multiple PDU logins,
           that was exposed due to removal of TCP prequeue support. (Florian

        Also, there is a iser-target bug still being worked on for post -rc1

        ib_post_send() failures, for RNICs with small max_send_sge"

      Second PPC KVM update for 4.16
      
      Seven fixes that are either trivial or that address bugs that people
      are actually hitting.  The main ones are:
      
      - Drop spinlocks before reading guest memory
      
      - Fix a bug causing corruption of VCPU state in PR KVM with preemption
        enabled
      
      - Make HPT resizing work on POWER9
      
      - Add MMIO emulation for vector loads and stores, because guests now
        use these instructions in memcpy and similar routines.
