no particular reason for them to be implemented in assembler and having them in C allows easier extension as well as using more C macros and {d,i}tlb_slot_max rather than hard-coding magic (and actually spitfire-only) values. - Fix the compilation of pmap_print_tte(). - Change pmap_print_tlb() to use ldxa() rather than re-rolling it inline as well as TLB_DAR_SLOT and {d,i}tlb_slot_max rather than hardcoding magic (and actually spitfire-only) values. - While at it, suffix the above mentioned functions with "_sun4u" to underline they're architecture-specific. - Use __FBSDID and macros instead of magic values in locore.S. - Remove unused includes and smp_stack in locore.S.
