SOFTWARE_SUSPEND requires PM on PPC?

[Horms]

Hi,

I haven't entirely investigated this, but it seems that CONFIG_PM needs
to be set for CONFIT_SOFFTWARE_SUSPEND to compile cleanly. For startes,
swsusp_arch_suspend needs swsusp_save. Sould SOFTWARE_SUSPEND required
PM, or should i add some strategic #ifdef CONFIG_PM to the code. This is
2.6.14, but i think its present in Linus' current git.

 arch/ppc/kernel/built-in.o: In function `swsusp_arch_suspend':
 : undefined reference to `swsusp_save'
 arch/ppc/kernel/built-in.o: In function `swsusp_arch_resume':
 : undefined reference to `pagedir_nosave'
 arch/ppc/kernel/built-in.o: In function `swsusp_arch_resume':
 : undefined reference to `pagedir_nosave'
 arch/ppc/platforms/built-in.o: In function `pmac_late_init':
 : undefined reference to `pm_set_ops'


Should PM require SOFTWARE_SUSPEND on PPC, or should the
calls to swsusp_save, pagedir_nosave, pagedir_nosave and pm_set_ops
be gaurded with #ifdef CONFIG_PM ?
