Hi all,

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

  arch/s390/include/asm/rwsem.h

between commit:

   91a1fad759ffd ("s390: use generic rwsem implementation")

from the s390 tree and commit:

   a61ba2c8a48f1 ("locking/arch, s390: Add __down_read_killable()")

from the tip tree.

I fixed it up by re-deleting the file 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.
