H A Dwild_bctr.cb7683fc6 Tue Jul 24 00:53:22 CDT 2018 Michael Ellerman <mpe@ellerman.id.au> selftests/powerpc: Add a test of wild bctr

This tests that a bctr (Branch to counter and link), ie. a function
call, to a wildly out-of-bounds address is handled correctly.

Some old kernel versions didn't handle it correctly, see eg:

"powerpc/slb: Force a full SLB flush when we insert for a bad EA"
