Hi all,
Today's linux-next merge of the bitmap tree got a conflict in:
include/linux/cpumask.h
between commit:
4e1a7df45480 ("cpumask: Add enabled cpumask for present CPUs that can be brought online")
from the arm64 tree and commit:
5c563ee90a22 ("cpumask: introduce assign_cpu() macro")
from the bitmap tree.
I fixed it up (I just did the obvious - 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.
