by UltraSparc-IV and -IV+ as well as SPARC64 V, VI, VII and VIIIfx CPUs. - Replace TLB_PCXR_PGSZ_MASK and TLB_SCXR_PGSZ_MASK with TLB_CXR_PGSZ_MASK which just is the complement of TLB_CXR_CTX_MASK instead of trying to assemble it from the page size bits which vary across CPUs. - Add macros for the remainder of the SFSR bits, which are useful for at least debugging purposes.
