Subject: linux-next: manual merge of the tip tree with the vfs tree

Hi all,

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

  arch/x86/kernel/cpu/intel_rdt_rdtgroup.c

between commit:

  58e4e43911f8 ("kernfs, sysfs, cgroup, intel_rdt: Support fs_context")

from the vfs tree and commit:

  a3dbd01e6c9d ("x86/intel_rdt: Create character device exposing pseudo-locked region")

from the tip tree.

I fixed it up (I think - 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
