Hi all,
Today's linux-next merge of the kvm tree got a conflict in:
arch/x86/include/asm/trace/hyperv.h
between commit:
58ec5e9c9044 ("x86/hyper-v: Trace PV IPI send")
from the tip tree and commit:
47c054685621 ("X86/Hyper-V: Add hyperv_nested_flush_guest_mapping ftrace support")
from the kvm 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

Hi Stephen:
Thanks for fix. I will discuss with maintainer about how to deal with
the issue.
