Andrea Arcangeli 1f5fee2cf2 userfaultfd: selftest: avoid my_bcmp false positives with powerpc
Keep a non-zero placeholder after the count, for the my_bcmp comparison
of the page against the zeropage.  The lockless increment between 255 to
256 against a lockless my_bcmp could otherwise return false positives on
ppc32le.
