This patch broke UML build (and approx 15 other archs):
dont-attempt-to-power-off-if-power-off-is-not-implemented.patch
LD .tmp_vmlinux1
kernel/built-in.o(.text+0x148e1): In function `sys_reboot':
kernel/sys.c:535: undefined reference to `pm_power_off'
So move declaration of pm_power_off (and with it pm_idle) from the
archs that do define it to kernel/sys.c. This should fix the link
problem, and at the same time remove some duplication.
