Subject[PATCH] create CONFIG_SUSPEND_UP_POSSIBLE
Date
From: Linus Torvalds <torvalds@linux-foundation.org>

Without this change, it is possible to build CONFIG_HIBERNATE
on all !SMP architectures, but not necessarily their SMP versions.

I don't know for sure if the architecture list under SUSPEND_UP_POSSIBLE
is correct. For now it simply matches the list for SUSPEND_SMP_POSSIBLE.
