It is very rare to find a current system which is both sufficiently resource constrained to want to compile out power management support and sufficiently power insensitive to be able to tolerate doing so.
Hmmm...

There are two competing standards for doing this: APM - and ACPI. If you want to use either one, say Y here and then also - to the requisite support below.
Good to see the PC-centric comments are going away :-)

The following architectures do not source "kernel/power/Kconfig":
alpha
cris
h8300
Kconfig
m32r
m68k
m68knommu
microblaze
parisc
score
sparc
tile
um
xtensa
Which means that (for now) I don't have to care that CONFIG_PM becomes
unclearable. Other people may care, though...
