- ------------------------------------------------------------------
powerpc fixes for 5.3 #2

An assortment of non-regression fixes that have accumulated since the start of
the merge window.

A fix for a user triggerable oops on machines where transactional memory is
disabled, eg. Power9 bare metal, Power8 with TM disabled on the command line, or
all Power7 or earlier machines.

Three fixes for handling of PMU and power saving registers when running nested
KVM on Power9.

Two fixes for bugs found while stress testing the XIVE interrupt controller
code, also on Power9.

A fix to allow guests to boot under Qemu/KVM on Power9 using the the Hash MMU
with >= 1TB of memory.

Two fixes for bugs in the recent DMA cleanup, one of which could lead to
checkstops.

And finally three fixes for the PAPR SCM nvdimm driver.
