Michael Ellerman	872d11bca9	selftests/powerpc: Skip vmx/vsx/tar/etc tests on older CPUs ... Some of our tests use VSX or newer VMX instructions, so need to be skipped on older CPUs to avoid SIGILL'ing. Similarly TAR was added in v2.07, and the PMU event used in the stcx fail test only works on Power8 or later.

Cyril Bur	65ca668f58	selftests/powerpc: Check for VSX preservation across userspace preemption ... Ensure the kernel correctly switches VSX registers correctly. VSX registers are all volatile, and despite the kernel preserving VSX across syscalls, it doesn't have to. Test that during interrupts and timeslices ending the VSX regs remain the same.
