[PATCH] Make the kernel NTP code hand 64-bit *unsigned* values to do_div() [try #3]

[David Howells <dhowells@redhat.com>]

From: David Howells <dhowells@redhat.com>

The kernel NTP code shouldn't hand 64-bit *signed* values to do_div().  Make it
instead hand 64-bit unsigned values.  This gets rid of a couple of warnings.
