Log Message:
* Wed Jul 25 2007 David Woodhouse <dwmw2 at infradead.org>
- Restore bcm43xx functionality
- Restore PowerMac suspend-to-ram via /sys/power/state
(since userspace forgot how to use the PMU ioctls)
- Restore ofpath functionality (IDE_PROC_FS=y)
linux-2.6-powerpc-generic-suspend-1-remove-dead-code.patch:
--- NEW FILE linux-2.6-powerpc-generic-suspend-1-remove-dead-code.patch ---
Subject: remove dead code in via-pmu68k
When suspend is ever implemented for pmu68k it really should follow the
generic pm_ops concept and not mirror the platform-specific /dev/pmu
device with ioctls on it. Hence, this patch removes the unused code there;
should the implementors need it they can look at via-pmu.c and/or the
history of the file.

Yes, it's more a hack. But the whole code is such a mess that I could
work for days fixing it. Don't feel like doing that right now.

linux-2.6-powerpc-generic-suspend-5-pmu-pm_ops.patch:
--- NEW FILE linux-2.6-powerpc-generic-suspend-5-pmu-pm_ops.patch ---
Subject: [PATCH] powermac: proper sleep management
After having removed the power management ops from powermac completely, this
patch adds them back for PMU based machines, directly in the PMU driver.
This finally allows suspending via /sys/power/state on powerbooks.
The patch also replaces the PMU ioctl with a simple call to
pm_suspend(PM_SUSPEND_MEM) and puts the sleep-related PMU ioctls onto the
feature-removal schedule.

+What: /dev/pmu suspend/can-suspend ioctls
