    [PATCH] powerpc: Cleanup LOADADDR etc. asm macros · e58c3495
    David Gibson authored
    This patch consolidates the variety of macros used for loading 32 or
    64-bit constants in assembler (LOADADDR, LOADBASE, SET_REG_TO_*).  The
    idea is to make the set of macros consistent across 32 and 64 bit and
    to make it more obvious which is the appropriate one to use in a given
    situation.  The new macros and their semantics are described in the
    comments in ppc_asm.h.
    
    In the process, we change several places that were unnecessarily using
    immediate loads on ppc64 to use the GOT/TOC.  Likewise we cleanup a
    couple of places where we were clumsily subtracting PAGE_OFFSET with
    asm instructions to use assemble-time arithmetic or the toreal() macro
    instead.
