(trimming Cc list again)
I thought that patch was still current, what other way are we fixing it now?
Since I'm planning to do one more series for 2.6.37 to take care of the
remaining BKL users, should I push the patch above plus the one that
marks the module as "depends on !PREEMPT || BROKEN", or should that go through
the DRM tree?
Pavel: The only board that has this chipset with multiple sockets is for
Pentium III and does not have hotplug sockets, so num_present_cpus
is the same as num_possible_cpus here. I can change it to num_possible_cpus
of course.
