Subject: [GIT PULL] parisc fixes for 2.6.38-rc1

This is just a couple of minor parisc specific fixes.  One for a console
line wrap issue and the other for the transparent hugepages compile
failure.  We've run these through our usual build and boot checks.

The patches are here:

master.kernel.org:/pub/scm/linux/kernel/git/jejb/parisc-2.6.git#fixes

The short changelog is:

Guy Martin (1):
      parisc : Remove broken line wrapping handling pdc_iodc_print()

James Bottomley (1):
      parisc: fix compile breakage caused by inlining maybe_mkwrite
