    sparc64: Kill .fixup section bloat. · 40bdac7d
    David S. Miller authored
    This is an implementation of a suggestion made by Chris Torek:
    --------------------
    Something else I noticed in passing: the EX and EX_LD/EX_ST macros
    scattered throughout the various .S files make a fair bit of .fixup
    code, all of which does the same thing.  At the cost of one symbol
    in copy_in_user.S, you could just have one common two-instruction
    retl-and-mov-1 fixup that they all share.
    --------------------
    
    The following is with a defconfig build:
    
       text	   data	    bss	    dec	    hex	filename
