[MIPS] Use USECS_PER_SEC / HZ instead of tick_usec in do_gettimeofday. The 'tick_usec' is USER_HZ period in usec. do_gettimeofday() should use kernel HZ value. Here is a patch for MIPS. It seems m32r, m68k and sparc have same problem though their HZ and USER_HZ are same for now. Signed-off-by: Atsushi Nemoto <[e-mail]> Signed-off-by: Ralf Baechle <[e-mail]>
