PM: fix new mutex-locking bug in the PM core

2008-03-04T22:47:05+00:00

This patch (as1041) fixes a bug introduced by the
acquire-all-device-semaphores reversion.  The error pathway of
dpm_suspend() fails to reacquire a mutex it should be holding.

PM: Do not acquire device semaphores upfront during suspend

2008-03-04T22:47:05+00:00

Remove the code that acquires all device semaphores from the suspend
code path as it causes multiple problems to appear (most notably,
http://bugzilla.kernel.org/show_bug.cgi?id=10030) and revert the
change introduced by commit 4145ed6dc597a9bea5f6ae8c574653b2de10620f
depending on the code being removed.

Remove pm_sleep_lock()/pm_sleep_unlock() from device_add() to avoid
the issue reported at http://bugzilla.kernel.org/show_bug.cgi?id=9874.

It should fix the regreesions reported at:
	http://bugzilla.kernel.org/show_bug.cgi?id=9874

PM: Export device_pm_schedule_removal

2008-02-02T23:14:48+00:00

Move the declaration of device_pm_schedule_removal() to device.h
and make it exported, as it will be used directly by some drivers
for unregistering device objects during suspend/resume cycles in a
safe way.

PM: Make PM_TRACE more architecture independent

2008-02-01T23:30:54+00:00

When trying to debug a suspend failure I started implementing
PM_TRACE for powerpc. I then noticed that I'm debugging a suspend
failure and so PM_TRACE isn't useful at all, but thought that
nonetheless this could be useful in the future.

Basically, to support PM_TRACE, you add a Kconfig option that
selects PM_TRACE and provides the infrastructure as per the
help text of PM_TRACE.

driver core: clean up device_shutdown

2008-01-25T04:40:25+00:00

device_shutdown does not need to be in a separate file.  Move it into
the driver core file where it belongs.

This also moves us one more step closer to making devices_kset static,
now only the crazy sysdevs are keeping that from happening...
