powerpc: Make core sibling information available to userspace Implement the notion of "core siblings" for powerpc. This makes /sys/devices/system/cpu/cpu*/topology/core_siblings present sensible values, indicating online CPUs which share an L2 cache. BenH: Made cpu_to_l2cache() use of_find_node_by_phandle() instead of IBM-specific open coded search Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
