Subject[RFC 07/15] x86_64: Replace xxx_pda() operations in include_asm-x86_hardirq_64_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
