Hi all,

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

  kernel/kprobes.c

between commits:

  49e0b4658fe6 ("kprobes: Convert kprobe_lookup_name() to a function")
  290e3070762a ("powerpc/kprobes: Fix handling of function offsets on ABIv2")

from the powerpc tree and commit:

  1d585e70905e ("trace/kprobes: Fix check for kretprobe offset within function entry")

from the tip 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
