Subject: PM: Fix dependencies of CONFIG_SUSPEND and CONFIG_HIBERNATION
From: Rafael J. Wysocki <rjw@xxxxxxx>
Dependencies of CONFIG_SUSPEND and CONFIG_HIBERNATION introduced by commit
296699de6bdc717189a331ab6bbe90e05c94db06 "Introduce CONFIG_SUSPEND for
suspend-to-Ram and standby" are incorrect, as they don't cover the facts
that (1) not all architectures support suspend and (2) SMP hibernation is
only possible on X86 and PPC64 (if PPC64_SWSUSP is set).

Allow the system to enter sleep states in which main memory is
powered and thus its contents are preserved, such as the
suspend-to-RAM state (i.e. the ACPI S3 state).
