It's a totally independent decision for the user whether he wants
suspend and/or hibernation support, and ACPI shouldn't care.

Commit bd804eba1c ("PM: Introduce
pm_power_off_prepare") caused problems in the poweroff path, as reported by
YOSHIFUJI Hideaki / 吉藤英明.
Generally, sysdev_shutdown() should be called after the ACPI preparation for
powering the system off. To make it happen, we can separate sysdev_shutdown()
from device_shutdown() and call it directly wherever necessary.

This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner
and the previous fixes for EDAC_MC and EDAC_DEVICE.
It removes the old (and incorrect) completion model and uses reference counts
on per instance kobjects and on the edac core module.
This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI
code was missed. In addition, this fixes a system hang after a low level
driver was unloaded. (A cleanup function was called twice, which really
screwed things up)

This fixes a deadlock that could occur on a 'setup' and 'teardown' sequence of
the workq for a edac_mc control structure instance. A similiar fix was
previously implemented for the edac_device code.
In addition, the edac_mc device code there was missing code to allow the workq
period valu to be altered via sysfs control.
This patch adds that fix on the code, and allows for the changing of the
period value as well.

This avoids use of the kernel-internal "xtime" variable directly outside
of the actual time-related functions. Instead, use the helper functions
that we already have available to us.
This doesn't actually change any behaviour, but this will allow us to
fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
(because much of the realtime information is maintained as separate
offsets to 'xtime'), which has caused interfaces that use xtime directly
to get a time that is out of sync with the real-time clock by up to a
third of a second or so.
