Greg Kroah-Hartman f005de0183 powerpc fixes for 4.19 #3
A reasonably big batch of fixes due to me being away for a few weeks.
 
 A fix for the TM emulation support on Power9, which could result in corrupting
 the guest r11 when running under KVM.
 
 Two fixes to the TM code which could lead to userspace GPR corruption if we take
 an SLB miss at exactly the wrong time.
 
 Our dynamic patching code had a bug that meant we could patch freed __init text,
 which could lead to corrupting userspace memory.
 
 csum_ipv6_magic() didn't work on little endian platforms since we optimised it
 recently.
 
 A fix for an endian bug when reading a device tree property telling us how many
 storage keys the machine has available.
 
 Fix a crash seen on some configurations of PowerVM when migrating the partition
 from one machine to another.
 
 A fix for a regression in the setup of our CPU to NUMA node mapping in KVM
 guests.
 
 A fix to our selftest Makefiles to make them work since a recent change to the
 shared Makefile logic.
 
 Thanks to:
   Alexey Kardashevskiy, Breno Leitao, Christophe Leroy, Michael Bringmann,
   Michael Neuling, Nicholas Piggin, Paul Mackerras,, Srikar Dronamraju, Thiago
