   This test fails on my SS20MP.
   
   Using PMAP_NC on remapping cpuinfo_data and removing SRMMU_PG_C
   on CPUINFO_VA mappings seems to fix the inconsistency (alias problem?),
   though it still fails later:

hmm.. what about removing the cache bit on the rest of the
cpuinfo_data mappings?  the ones from cpuinfo_data + cpuinfo_len
to cpuinfo_data + (cpuinfo_len * (sparc_ncpus-1)).


the old mappings were cached i thought, however.
