Subject: [PATCH 1/2] topology, cleanup: Avoid redefinition of cpumask_of_pcibus in asm header files.
From: Ganapatrao Kulkarni <gkulkarni@...iumnetworks.com>
At present cpumask_of_pcibus is defined for !CONFIG_NUMA and moving out
to common will allow to use for numa too. This also avoids
redefinition of this macro in respective architecture header files.
