[PATCH 3/4] Fix drivers/macintosh/mediabay.c when !CONFIG_ADB_PMU.

[PATCH 3/4] Fix drivers/macintosh/mediabay.c when !CONFIG_ADB_PMU.

[Tony Breeds]

When building drivers/macintosh/mediabay.c if CONFIG_ADB_PMU isn't defined we
get:
drivers/built-in.o: In function `media_bay_step':
mediabay.c:(.text+0x92b84): undefined reference to `pmu_suspend'
mediabay.c:(.text+0x92c08): undefined reference to `pmu_resume'

Create empty place holders in that scenario.

[PATCH 2/4] Fix build of modular drivers/macintosh/apm_emu.c

[Tony Breeds]

apm_emu.c needs access to pmu_batteries[] and friends.  If CONFIG_SUSPEND isn't
defined these symbols aren't exported and the build fails with:
  Building modules, stage 2.
ERROR: "pmu_batteries" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_battery_count" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_power_flags" [drivers/macintosh/apm_emu.ko] undefined!

Fix that.

[PATCH 1/4] Ensure that pmu_sys_suspended exists in appropriate configs.

[Tony Breeds]

pmu_sys_suspended is declared extern when:
	defined(CONFIG_PM_SLEEP) && defined(CONFIG_PPC32)
but only defined when:
	defined(CONFIG_SUSPEND) && defined(CONFIG_PPC32)
which is wrong.  Lets fix that.

As I wrote, this isn't defined in my config:

# CONFIG_SUSPEND is not set
CONFIG_HIBERNATION=y

Hmm okay I thought I tested 
for you.

I don't know if I missed it in one of your original posts, can you
supply your .config and compiler error.  I can't see anywhere outside
of:
$ git grep -E -l pmu_sys_suspended --
drivers/macintosh/via-pmu-led.c
drivers/macintosh/via-pmu.c
include/linux/pmu.h

where pmu_sys_suspended is referenced and I'm having difficulty
understanding how CONFIG_HIBERNATION is affecting that.

I mangled the filenames and didn't notice that you fixed the header file
instead of via-pmu.c. Yes, this should work. Thanks for fixing this 
and the apm-emu stuff as well.
