Richard Henderson April 2, 2014, 5:52 p.m. UTC 
As recently pointed out in a thread porting libitm to aarch64, the PAGE_SIZE
and FIXED_PAGE_SIZE macros are unused.  Indeed, not all of the ports actually
defined them at all.

Removed, lest they cause further confusion.


r~
* config/alpha/target.h (PAGE_SIZE, FIXED_PAGE_SIZE): Remove.
        * config/arm/target.h, config/sh/target.h: Likewise.
        * config/sparc/target.h, config/x86/target.h: Likewise.
