Nick Piggin fb0328e2e6 x86: reduce CONFIG_X86_PPRO_FENCE bloat 
CONFIG_X86_PPRO_FENCE bloats text:

i386 allmodconf: size mm/built-in.o
           text    data     bss     dec     hex         text ratio
vanilla: 163082   20372   40120  223574   36956          100.00%
bugfix : 163509   20372   40120  224001   36b01            0.26%
noppro : 162191   20372   40120  222683   365db         -  0.55%
both   : 162267   20372   40120  222759   36627         -  0.50% (+0.05% vs noppro)

So with the ppro memory ordering bug out of the way, the PG_uptodate fix
only adds 76 bytes of text.

allow this config to be specified by distros.
