#     selftests/powerpc: Add a test of sigreturning to an unaligned address
#     
#     Add a test of sigreturning to an unaligned address (low two bits set).
#     This should have no effect because the hardware will mask those bits.
#     However it previously falsely triggered a warning when
#     CONFIG_PPC_RFI_SRR_DEBUG=y.
