40bdac7dbc sparc64: Kill .fixup section bloat.
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
