[RFC 11/15] x86_64: Replace xxx_pda() operations in include_asm-x86_stackprotector_h

[Mike Travis]

  * 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
