Subject: linux-next: manual merge of the akpm-current tree with the arm64
 tree

Hi Andrew,

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

  include/uapi/linux/prctl.h

between commit:

  7582e22038a2 ("arm64/sve: Backend logic for setting the vector length")
  2d2123bc7c7f ("arm64/sve: Add prctl controls for userspace vector length management")

from the arm64 tree and commit:

  4391ebaac0d6 ("prctl: add PR_[GS]ET_PDEATHSIG_PROC")

from the akpm-current 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.

Cheers,
Stephen Rothwell
