Linus Torvalds 6b2c4d52fd Merge branch 'hch' (patches from Christoph)
Merge procfs splice read fixes from Christoph Hellwig:
 "Greg reported a problem due to the fact that Android tests use procfs
  files to test splice, which stopped working with the changes for
  set_fs() removal.

  This series adds read_iter support for seq_file, and uses those for
  various proc files using seq_file to restore splice read support"

[ Side note: Christoph initially had a scripted "move everything over"
  patch, which looks fine, but I personally would prefer us to actively
  discourage splice() on random files.  So this does just the minimal
  basic core set of proc file op conversions.

  For completeness, and in case people care, that script was

     sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g'

  but I'll wait and see if somebody has a strong argument for using
  splice on random small /proc files before I'd run it on the whole
  kernel.   - Linus ]
