[PATCH 0/2] lpfc: PowerPC64 topology information, and per-core scheduling

[Mauricio Faria de Oliveira]

This series enables the association of IO channels at the CPU-core level (i.e.,
with all CPUs/threads of core), which may increase performance depending on the
CPU affinity settings of the workload (e.g., benefit from the per-core caches);
and adds the required pieces to use it on PowerPC64 too (topology information),
which has server processors with many cores/threads and per-core caches.

Although the series include bits for PowerPC64, the per-core scheduling patch
is architecture independent.

Tested on next-20160601 (with an extra commit for patch 1/2, see commit msg).

Mauricio Faria de Oliveira (2):
  lpfc: support for CPU phys_id and core_id on PowerPC64
  lpfc: add option for lpfc_fcp_io_sched (LPFC_FCP_SCHED_BY_CPU_CORE)

FYI, that commit has been accepted into powerpc next [1].
