Subject: kernel/time.c: change jiffies_to_clock_t() input parameter's type to unsigned long
From: hank <pyu@redhat.com>

The parameter's origin type is long.  On an i386 architecture, it can
easily be larger than 0x80000000, causing this function to convert it to a
sign-extended u64 type.  Change the type to unsigned long so we get the
correct result.
