[SPARC64]: Fix sparse errors in arch/sparc64/kernel/traps.c
Add 'UL' markers to DCU_* macros. Declare C functions called from assembler in entry.h Declare C functions called from within the sparc64 arch code in include/asm-sparc64/*.h headers as appropriate. Remove unused routines in traps.c Signed-off-by: David S. Miller <davem@davemloft.net>
