I was wrong here.  The patches are mis-labelled.  The patches labelled
'v2' are deltas regressing to an older version of the series.

This is currently in akpm/next:

if you remove the patches that match /random-address-requests-v2$/, then
things should be good.  I've confirmed that

  b990c09770d3 random: simplify API for random address requests

is the proper version and that every other patch on top of that
correctly adds randomize_page().  It's the ones labelled 'v2' that are
reverting changes to an older version of the series (randomize_addr).

It's a build failure that only occurs when a bisect would land in the
middle of the old series.  Removing the patches labelled v2 should fix
it.

Sorry for the confusion.

thx,

Jason.
