Subject: linux-next: manual merge of the bitmap tree with the random tree

Hi all,

Today's linux-next merge of the bitmap tree got a conflict in:

  include/linux/nodemask.h

between commit:

  82f33a32b4d2 ("treewide: use prandom_u32_max() when possible")

from the random tree and commit:

  97848c10f9f8 ("lib/bitmap: remove bitmap_ord_to_pos")

from the bitmap tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
