2003-06-06	[PATCH] Move cpu notifiers et al to cpu.h	Rusty Russell
	Trivial patch: when these were introduced cpu.h didn't exist.
2002-10-29	[PATCH] slab: extended cpu notifiers	Andrew Morton
	Patch from Dipankar Sarma <dipankar@in.ibm.com> This is Manfred's patch which provides a CPU_UP_PREPARE cpu notifier to allow initialization of per_cpu data just before the cpu becomes fully functional. It also provides a facility for the CPU_UP_PREPARE handler to return NOTIFY_BAD to signify that the CPU is not permitted to come up. If that happens, a CPU_UP_CANCELLED message is passed to all the handlers. The patch also fixes a bogus NOFITY_BAD return from the softirq setup code. Patch has been acked by Rusty. We need this mechanism in slab for starting per-cpu timers and for allocating the per-cpu slab hgead arrays before the CPU has come up and started using slab.

2002-07-26	[PATCH] Hot-plug CPU Boot Changes	Rusty Russell
	This patch alters the boot sequence to "plug in" each CPU, one at a time. You need the patch for each architecture, as well. The interface used to be "smp_boot_cpus()", "smp_commence()", and each arch implemented the "maxcpus" boot arg itself. With this patch, it is: smp_prepare_cpus(maxcpus): probe for cpus and set up cpu_possible(cpu). __cpu_up(cpu): called after initcalls, for each cpu where cpu_possible(cpu) is true. smp_cpus_done(maxcpus): called after every cpu has been brought up
