At this point, I think these patches are plausible candidates for inclusion
into 4.11.  Whether they want backporting is a slightly harder matter, as
these patches necesserily alter some error values for the get/set_debug_reg()
hypercalls.

If however there is objection to these going into 4.11, they can sit in
x86-next until the 4.12 window opens.

Andrew Cooper (3):
  x86/pv: Introduce and use x86emul_read_dr()
  x86/pv: Introduce and use x86emul_write_dr()
  x86/traps: Misc non-functional improvements to set_debugreg()
