Changeset 32f3e34 in rtems for c/src/lib/libbsp/i386/i386ex/start

Patch from Erik Ivanenko <erik.ivanenko@…>:

Please find attached a start.s that includes a cli prior to the hlt
instruction. This ensures that external interrupts cannot restart
the system after returning to the startup code. ( According to the hlt
docs, they will! )

Also find a new timer.c. ( I forgot to update the countdowm value
in the timer when I changed the PSCLK frequency in start.s) . This
improves timer accuracy.

The raw_idt_notify messages are no longer infinite, I tested sp11 and
sp05, both which were bad, and I have seen the message print once in
one test. I think it's ok if it prints out once. In fact, I don't
think you can effectively stop it!
