Michael Ellerman	192b2e742c	selftests/powerpc: Skip tm-trap if transactional memory is not enabled ... Some processor revisions do not support transactional memory, and additionally kernel support can be disabled. In either case the tm-trap test should be skipped, otherwise it will fail with a SIGILL.

Gustavo Romero	a08082f8e4	powerpc/selftests: Check endianness on trap in TM ... Add a selftest to check if endianness is flipped inadvertently to BE (MSR.LE set to zero) on BE and LE machines when a trap is caught in transactional mode and load_fp and load_vec are zero, i.e. when MSR.FP and MSR.VEC are zeroed (disabled).
