  - Merge "[IDF] arm-pod7: Configure hugepages and cpupinning variables for armpod7"
  - [IDF] arm-pod7: Configure hugepages and cpupinning variables for armpod7

    For non-dpdk scenarios we define as cpu config:
            0,1 for OS
            2-7 for nova
    For dpdk scenarios we define as cpu config:
            0,1 for OS,
            2,3 for DPDK drivers and processes
            4-7 for nova

    Dpdk config is also provided for the 3 thunderx nodes which currently
    serve as KVM nodes. The config is similar to the config above with
    cores 4-47 being used for nova.
