Subject: [PATCH 1/1] Change jiffies_to_clock_t function input parameter's
 type to unsigned long

The parmaeter's origin type is long. On an i386 architecture, it can easily
larger than 0x80000000, then this function convert it to a u64 type, get a
result: 0xffffffff80000000, it is unexpected, so change the type to
unsigned long, we can get the correct result: 0x0000000080000000
