#     selftests/powerpc: Fix fpu_signal failures
#     
#     My recent commit e5d00aaac651 ("selftests/powerpc: Check all FPRs in
#     fpu_preempt") inadvertently broke the fpu_signal test.
#     
#     It needs to take into account that fpu_preempt now loads 32 FPRs, so
#     enlarge darray.
#     
#     Also use the newly added randomise_darray() to properly randomise darray.
#     
#     Finally the checking done in signal_fpu_sig() needs to skip checking
#     f30/f31, because they are used as scratch registers in check_all_fprs(),
#     called by preempt_fpu(), and so could hold other values when the signal
#     is taken.
#
