powerpc/mce: Fix SLB rebolting during MCE recovery path. (2018-08-23 23:40:10 +1000)

- ------------------------------------------------------------------
powerpc fixes for 4.19 #2

- An implementation for the newly added hv_ops->flush() for the OPAL hvc
console driver backends, I forgot to apply this after merging the hvc driver
changes before the merge window.

- Enable all PCI bridges at boot on powernv, to avoid races when multiple
children of a bridge try to enable it simultaneously. This is a workaround
until the PCI core can be enhanced to fix the races.

- A fix to query PowerVM for the correct system topology at boot before
initialising sched domains, seen in some configurations to cause broken
scheduling etc.

- A fix for pte_access_permitted() on "nohash" platforms.

- Two commits to fix SIGBUS when using remap_pfn_range() seen on Power9 due to
a workaround when using the nest MMU (GPUs, accelerators).

- Another fix to the VFIO code used by KVM, the previous fix had some bugs
which caused guests to not start in some configurations.

- A handful of other minor fixes.

Thanks to:
Aneesh Kumar K.V, Benjamin Herrenschmidt, Christophe Leroy, Hari Bathini, Luke
Dashjr, Mahesh Salgaonkar, Nicholas Piggin, Paul Mackerras, Srikar Dronamraju.
