Patchsets related to hibernation resume:
  - enhancement to make the use of an existing resume file more general
  - enhance name_to_dev_t to ignore trailing newlines coming from userspace.

Both patches are based on the 3.12-rc3 tag.  This was tested on a
Pandaboard with partial hibernation support, and compiled for x86.

[PATCH 1/2] init/do_mounts.c: ignore final \n in name_to_dev_t
  init/do_mounts.c |   23 ++++++++++++++++++-----
  1 file changed, 18 insertions(+), 5 deletions(-)

  Changes name_to_dev_t to handle a trailing newline in the
  input buffer, which will allow name_to_dev_t to be used
  directly with user buffers without requiring a copy.
  Also adds a const to the name parameter which reflects
  how name_to_dev_t is treating the input buffer currently.
  This also allows direct use of user buffers
  (from resume_store for example).

[PATCH 2/2] PM / Hibernate: use name_to_dev_t to parse resume
  kernel/power/hibernate.c |   15 ++++-----------
  1 file changed, 4 insertions(+), 11 deletions(-)

  Use name_to_dev_t to parse the /sys/power/resume file making the
  syntax more flexible.  It supports the previous use syntax
  and additionally can support other formats such as
  /dev/devicenode and UUID= formats.

  By changing /sys/debug/resume to accept the same syntax as
  the resume=device parameter, we can parse the resume=device
  in the initrd init script and use the resume device directly
  from the kernel command line.

Changes in v3:
--------------
* Dropped documentation patch as it went in through trivial
* Added patch for name_to_dev_t to support directly parsing userspace
  buffer

Changes in v2:
--------------
* Added check for null return of kstrndup in hibernate.c

Thanks,

Sebastian
