Subject: Re: candidates for @devel-rt localversion-rt++

FYI, per kvm unit tests, 4.16-rt definitely has more kvm issues.

huawei5:/abuild/mike/kvm-unit-tests # uname -r
4.16.18-rt11-rt
huawei5:/abuild/mike/kvm-unit-tests # ./run_tests.sh
PASS selftest-setup (2 tests)
FAIL selftest-vectors-kernel 
FAIL selftest-vectors-user 
PASS selftest-smp (65 tests)
PASS pci-test (1 tests)
PASS pmu (3 tests)
FAIL gicv2-ipi 
FAIL gicv3-ipi 
FAIL gicv2-active 
FAIL gicv3-active 
PASS psci (4 tests)
FAIL timer

4.14-rt passes all tests.  The above is with the kvm raw_spinlock_t
conversion patch applied, but the 4.12 based SLERT tree I cloned to
explore arm-land in the first place shows only one timer failure, and
has/needs it applied as well, which would seem to vindicate it.
