  powerpc/mm/hash: Fix sharing context ids between kernel & userspace (2020-01-23 21:26:20 +1100)

- ------------------------------------------------------------------
powerpc fixes for 5.5 #6

Fix our hash MMU code to avoid having overlapping ids between user and kernel,
which isn't as bad as it sounds but led to crashes on some machines.

A fix for the Power9 XIVE interrupt code, which could return the wrong interrupt
state in obscure error conditions.

A minor Kconfig fix for the recently added CONFIG_PPC_UV code.

Thanks to:
  Aneesh Kumar K.V, Bharata B Rao, Cédric Le Goater, Frederic Barrat.
