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

Hi all,

Today's linux-next merge of the sysctl tree got conflicts in:

  include/linux/perf_event.h
  kernel/events/core.c

between commit:

  e6814ec3ba19 ("perf/core: Rename perf_proc_update_handler() -> perf_event_max_sample_rate_handler(), for readability")

from Linus' tree and commit:

  c8be9e66ca1e ("sysctl: treewide: constify the ctl_table argument of handlers")

from the sysctl 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
