      Pull the leap second fixes from Thomas Gleixner:
       "It's a rather large series, but well discussed, refined and reviewed.
        It got a massive testing by John, Prarit and tip.
      
        In theory we could split it into two parts.  The first two patches
      
          f55a6faa: hrtimer: Provide clock_was_set_delayed()
          4873fa07: timekeeping: Fix leapsecond triggered load spike issue
      
        are merely preventing the stuff loops forever issues, which people
        have observed.
      
        But there is no point in delaying the other 4 commits which achieve
        full correctness into 3.6 as they are tagged for stable anyway.  And I
        rather prefer to have the full fixes merged in bulk than a "prevent
        the observable wreckage and deal with the hidden fallout later"
        approach."

      x86/vsyscall: allow seccomp filter in vsyscall=emulate · 5651721e
      Will Drewry authored
      If a seccomp filter program is installed, older static binaries and
      distributions with older libc implementations (glibc 2.13 and earlier)
      that rely on vsyscall use will be terminated regardless of the filter
      program policy when executing time, gettimeofday, or getcpu.  This is
      only the case when vsyscall emulation is in use (vsyscall=emulate is the
      default).
      
      This patch emulates system call entry inside a vsyscall=emulate by
      populating regs->ax and regs->orig_ax with the system call number prior
      to calling into seccomp such that all seccomp-dependencies function
      normally.  Additionally, system call return behavior is emulated in line
      with other vsyscall entrypoints for the trace/trap cases.
      
      [ v2: fixed ip and sp on SECCOMP_RET_TRAP/TRACE (thanks to luto@mit.edu) ]

      block: fix infinite loop in __getblk_slow · 91f68c89
      Jeff Moyer authored
      Commit 080399aa ("block: don't mark buffers beyond end of disk as
      mapped") exposed a bug in __getblk_slow that causes mount to hang as it
      loops infinitely waiting for a buffer that lies beyond the end of the
      disk to become uptodate.
      
      The problem was initially reported by Torsten Hilbrich here:
      
          https://lkml.org/lkml/2012/6/18/54
      
      and also reported independently here:
      
          http://www.sysresccd.org/forums/viewtopic.php?f=13&t=4511
      
      and then Richard W.M.  Jones and Marcos Mello noted a few separate
      bugzillas also associated with the same issue.  This patch has been
      confirmed to fix:
      
          https://bugzilla.redhat.com/show_bug.cgi?id=835019
      
      The main problem is here, in __getblk_slow:
      
              for (;;) {
                      struct buffer_head * bh;
                      int ret;
      
                      bh = __find_get_block(bdev, block, size);
                      if (bh)
                              return bh;
      
                      ret = grow_buffers(bdev, block, size);
                      if (ret < 0)
                              return NULL;
                      if (ret == 0)
                              free_more_memory();
              }
      
      __find_get_block does not find the block, since it will not be marked as
      mapped, and so grow_buffers is called to fill in the buffers for the
      associated page.  I believe the for (;;) loop is there primarily to
      retry in the case of memory pressure keeping grow_buffers from
      succeeding.  However, we also continue to loop for other cases, like the
      block lying beond the end of the disk.  So, the fix I came up with is to
      only loop when grow_buffers fails due to memory allocation issues
      (return value of 0).
      
      The attached patch was tested by myself, Torsten, and Rich, and was
      found to resolve the problem in call cases.
