Hi,
while working on something unrelated I've checked the current usage
of __GFP_REPEAT in the tree. It seems that a good half of it is
and always has been bogus because __GFP_REPEAT has always been about
high order allocations while we are using it for order-0 or very small
orders very often. It seems that a big pile of them is just a copy&paste
when a code has been adopted from one arch to another.

I think it makes some sense to get rid of them because they are just
making the semantic more unclear.

The series is based on linux-next tree and
$ git grep __GFP_REPEAT next/master | wc -l
106

and with the patch
$ git grep __GFP_REPEAT  | wc -l
44

There are probably more users which do not need the flag but I have focused
on the trivially superfluous ones here.
