Merge tag 'powerpc-5.2-6' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
"One fix for a bug in our context id handling on 64-bit hash CPUs,
which can lead to unrelated processes being able to read/write to each
other's virtual memory. See the commit for full details.
That is the fix for CVE-2019-12817.
This also adds a kernel selftest for the bug"
