Hi Dan,
Today's linux-next merge of the nvdimm tree got a conflict in:
arch/parisc/include/uapi/asm/mman.h
between commit:
48cd4dc8f57f ("parisc: Convert MAP_TYPE to cover 4 bits on parisc")
from the parisc-hd tree and commit:
1c9725974074 ("mm: introduce MAP_SHARED_VALIDATE, a mechanism to safely define new mmap flag")
from the nvdimm 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.
