Patchset related to hibernation resume: one enhancement to make the use of an existing file more general and one documentation update.
Both patches are based on the 3.11-rc6 tag. This was tested on a Pandaboard with partial hibernation support, and compiled on x86.
Further testing is needed on other platforms. Please let me know if you're able to verify this on any other systems.
[PATCH 1/2] PM / Hibernate: use name_to_dev_t to parse resume 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.

[PATCH 2/2] PM / Hibernate: add section for resume options This adds a small section to the swsusp.txt file to address the options for resuming. This comments on the manual resume option which is used when resorting to an initrd or initramfs for resuming. Resuming from late init is discussed later in the document, but it seemed appropriate to list them together.
