      Merge branch 'parisc-4.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux · 5975b2c0
      Linus Torvalds authored
      Pull parisc fixes from Helge Deller:
      
       - Fix printk time stamps on SMP systems which got wrong due to a patch
         which was added during the merge window
      
       - Fix two bugs in the stack backtrace code: Races in module unloading
         and possible invalid accesses to memory due to wrong instruction
         decoding (Mikulas Patocka)
      
       - Fix userspace crash when syscalls access invalid unaligned userspace
         addresses.  Those syscalls will now return EFAULT as expected.
         (tagged for stable kernel series)

      devpts: Make each mount of devpts an independent filesystem. · eedf265a
      Eric W. Biederman authored
      The /dev/ptmx device node is changed to lookup the directory entry "pts"
      in the same directory as the /dev/ptmx device node was opened in.  If
      there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx
      uses that filesystem.  Otherwise the open of /dev/ptmx fails.
      
      The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that
      userspace can now safely depend on each mount of devpts creating a new
      instance of the filesystem.
      
      Each mount of devpts is now a separate and equal filesystem.
      
      Reserved ttys are now available to all instances of devpts where the
      mounter is in the initial mount namespace.
      
      A new vfs helper path_pts is introduced that finds a directory entry
      named "pts" in the directory of the passed in path, and changes the
      passed in path to point to it.  The helper path_pts uses a function
      path_parent_directory that was factored out of follow_dotdot.
      
      In the implementation of devpts:
       - devpts_mnt is killed as it is no longer meaningful if all mounts of
         devpts are equal.
       - pts_sb_from_inode is replaced by just inode->i_sb as all cached
         inodes in the tty layer are now from the devpts filesystem.
       - devpts_add_ref is rolled into the new function devpts_ptmx.  And the
         unnecessary inode hold is removed.
       - devpts_del_ref is renamed devpts_release and reduced to just a
         deacrivate_super.
       - The newinstance mount option continues to be accepted but is now
         ignored.
      
      In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as
      they are never used.
      
      Documentation/filesystems/devices.txt is updated to describe the current
      situation.
      
      This has been verified to work properly on openwrt-15.05, centos5,
      centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3,
      ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1,
      slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01.  With the
      caveat that on centos6 and on slackware-14.1 that there wind up being
      two instances of the devpts filesystem mounted on /dev/pts, the lower
      copy does not end up getting used.
