Subject: linux-next: manual merge of the hyperv tree with the tip tree

Hi all,

Today's linux-next merge of the hyperv tree got a conflict in:

  arch/x86/include/asm/mshyperv.h

between commit:

  a0e2bf7cb700 ("x86/paravirt: Switch time pvops functions to use static_call()")

from the tip tree and commit:

  eb3e1d370b4c ("clocksource/drivers/hyper-v: Handle sched_clock differences inline")

from the hyperv tree.

I fixed it up (I used the latter version of this file and then applied the
following patch) 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.
