| |
This patch set converts sparc64 over to use the dynamic per-cpu stuff.
Most of the work is the boring task of getting rid of the special "real_setup_per_cpu_areas()" sparc64 uses to setup the per-cpu areas before bootmem is available. We needed to do this because we initialized the cpu possible map at the same time as the stuff stored in the per-cpu cpu_data array.
So we split those tasks up. Otherwise we wouldn't be able to convert to dynamic per-cpu because that stuff requires that bootmem and the page structs are ready to use.
For now I'm using the draconian unoptimized x86 NUMA remap scheme. I really want to do this better because it is insanely suboptimal on Niagara chips where in some cases 8 cpus share the same physical TLB.
This is against Linus's current tree and it's also in sparc-next-2.6
