Hi Andrew,
Today's linux-next merge of the akpm tree got a conflict in:
kernel/jump_label.c
between commit:
e3f91083facb ("jump_label: Make it possible for arches to invoke jump_label_init() earlier")
from the powerpc tree and patch:
"jump_label: remove bug.h, atomic.h dependencies for HAVE_JUMP_LABEL"
from the akpm 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.
