Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
arch/s390/hypfs/hypfs_diag.c
between commit:
e030c1125eab ("s390/hypfs: use basic block for diag inline assembly")
from the s390 tree and commit:
e65f30e0cb29 ("s390: hypfs: Move diag implementation and data definitions")
from the kvm tree.
I fixed it up (my fixup patch now looks like 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.
