    Subject[RFC 13/15] x86_64: Replace xxx_pda() operations in include_asm-x86_topology_h
      * It is now possible to use percpu operations for pda access
    since the pda is in the percpu area. Drop the pda operations.

    Thus:

    read_pda --> x86_read_percpu
    write_pda --> x86_write_percpu
    add_pda (+1) --> x86_inc_percpu
    or_pda --> x86_or_percpu

    Based on linux-2.6.tip/master
