      except, again, POLLFREE and POLL_BUSY_LOOP.
      
      With this, we finally get to the promised end result:
      
       - POLL{IN,OUT,...} are plain integers and *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
         mangle/demangle)
      
       - same behavior as after the first series (i.e. sparc et.al. epoll(2)
         working correctly).

      vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
      Linus Torvalds authored
      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.

      Linus Torvalds authored
      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
                  L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`

            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
           mangle/demangle)
      
         - same behavior as after the first series (i.e. sparc et.al. epoll(2)
           working correctly)"

      nios2: dts: Remove leading 0x and 0s from bindings notation · 5d13c731
      Mathieu Malaterre authored
      Improve the DTS files by removing all the leading "0x" and zeros to fix the
      following dtc warnings:
      
      Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
      
      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
      Boris Brezillon authored
      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 authored
      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.

      powerpc/pci: Fix broken INTx configuration via OF · c591c2e3
      Alexey Kardashevskiy authored
      59f47eff ("powerpc/pci: Use of_irq_parse_and_map_pci() helper")
      replaced of_irq_parse_pci() + irq_create_of_mapping() with
      of_irq_parse_and_map_pci(), but neglected to capture the virq
      returned by irq_create_of_mapping(), so virq remained zero, which
      caused INTx configuration to fail.
      
      Save the virq value returned by of_irq_parse_and_map_pci() and correct
      the virq declaration to match the of_irq_parse_and_map_pci() signature.

      This function returns realloc'ed memory, so the returned pointer
      must be passed to free() when done.  So, 'const' qualifier is odd.
      It is allowed to modify the expanded string.
