[SPARC64]: Fix sched_clock() wrapping every ~17 seconds. Unfortunately, sparc64 doesn't have an easy way to do a "64 X 64 --> 128" bit multiply like PowerPC and IA64 do. We were doing a "64 X 64 --> 64" bit multiple which causes overflow very quickly with a 30-bit quotient shift. So use a quotientshift count of 10 instead of 30, just like x86 and ARM do. This also fixes the wrapping of printk timestamp values every ~17 seconds. Signed-off-by: David S. Miller <davem@davemloft.net>
