linux-next: manual merge of the xarray tree with the kselftest tree

[broonie]

Hi all,

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

  tools/include/linux/kernel.h

between commits:

  d6e6a27d960f9 ("tools: Fix math.h breakage")
  066b34aa5461f ("tools: fix ARRAY_SIZE defines in tools and selftests hdrs")

from the kselftest and origin trees and commit:

  f2aa11fd51440 ("tools: Fix math.h breakage")

from the xarray 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.

Thank you. I will keep track of this when I send pull request.

I've dropped that commit from the XArray tree since d6e6a27d960f9
was essentially f2aa11fd51440 applied to Linus' tree.  The only change
left in the XArray tree today is a documentation update.

As long as what you have merges cleanly against Linus' tree (and I see
the "conflict" -- __round_mask() is defined adjacent to ARRAY_SIZE()),
then it'll be fine.  You might want to rebase to a more recent Linus
tree to get rid of the conflict.

When I applied on rc4 base, I didn't see any problems. This is a minor
one - I can mention this when I send my pull request. Shouldn't be a
problem.
