HRT_FROM_8254() bug

Hello,

I am using rtlinux-3.0, kernel2.2.18 on an i386 (amd k6-2) and I have
noticed that HRT_FROM_8254() bugs if you give it an argument greater than
0x7FFFFFFF.  This is causing crashes (division errors) when I call the
compatibility function rt_task_make_periodic(), which calls
HRT_FROM_8254() to convert from RTIME to hrtime_t to translate arguments
into the newer api.

Frank
