bitkeeper revision 1.1548 (4294554btfa2GpomqV57KFpxEHsjEA)
Move to Linux's cpumask_t and 'hotplug' multi-processor booting
interfaces. This also brings apic.c and various other files closer to
their Linux 2.6 equivalents. Simplified the scheduler interfaces a
little (particularly per-cpu and idle-domain initialisation).
