James Hogan d33ac60bea PM: Add sysfs attr for rechecking dev hash from PM trace
If the device which fails to resume is part of a loadable kernel module
it won't be checked at startup against the magic number stored in the
RTC.

Add a read-only sysfs attribute /sys/power/pm_trace_dev_match which
contains a list of newline separated devices (usually just the one)
which currently match the last magic number. This allows the device
which is failing to resume to be found after the modules are loaded
again.

Frans Pop b25f29b0da pm: document use of RTC in pm_trace
As pm_trace uses the system's hardware clock to save its magic value,
users of that option should be warned that using this debug option will
result in an incorrect system time after resume.

Pavel Machek 06df6a5c18 [PATCH] s2ram debugging documentation
Linus posted quite nice TRACE_RESUME how-to, and I think it is too nice to
be hidden in archives of mailing list, so I turned it into Documentation
piece.
