[PATCH 1/2] PCI: Add mechanism to find topologically near cores

2015-12-23 Thread Daniel J Blueman
Some devices (eg ixgbe) make assumptions about device to core locality when specifying interrupts locality hints and allocate starting from core 0. Moreover, interrupts may not be routable to distant NUMA nodes due to the 8-bit APIC ID space limitations. Provide a mechanism drivers can use to
