Subject: [PATCH next&mainline] oprofile: fix build when CONFIG_PM is
 disabled

From: Randy Dunlap <randy.dunlap@...cle.com>

Using do/while for a function-returning-a-value does not
make gcc happy, so change it to a static inline function.
(happens when CONFIG_PM is not enabled)

arch/x86/oprofile/nmi_int.c:784: error: expected expression before 'do'
