Subject: linux-next: manual merge of the ftrace tree with Linus' tree

Hi all,

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

  scripts/sorttable.h

between commit:

  0210d251162f ("scripts/sorttable: fix orc_sort_cmp() to maintain symmetry and transitivity")

from Linus' tree and commit:

  4f1d0c914628 ("scripts/sorttable: Move code from sorttable.h into sorttable.c")

from the ftrace tree.

I fixed it up (I deleted the file and applied the following merge fix
patch) 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.
