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.
