powerpc: Update cpu_sibling_maps dynamically
Rather doing one initialization pass over all the per-cpu cpu_sibling_maps at boot, update the maps at cpu online/offline time. This is a behavior change -- the thread_siblings attribute now reflects only online siblings, whereas it would display offline siblings before. The new behavior matches that of x86, and is arguably more useful. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
