      mvpp2: fix multicast address filter · 7ac8ff95
      Mikulas Patocka 提交于
      IPv6 doesn't work on the MacchiatoBIN board. It is caused by broken
      multicast address filter in the mvpp2 driver.
      
      The driver loads doesn't load any multicast entries if "allmulti" is not
      set. This condition should be reversed.
      
      The condition !netdev_mc_empty(dev) is useless (because
      netdev_for_each_mc_addr is nop if the list is empty).
      
      This patch also fixes a possible overflow of the multicast list - if
      mvpp2_prs_mac_da_accept fails, we set the allmulti flag and retry.

      unify {de,}mangle_poll(), get rid of kernel-side POLL... · 7a163b21

      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)

      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.

            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
           mangle/demangle)

      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
