Hi Peter and Andrzej,
the following four files in hw/ are using rt_clock directly
omap1.c
pxa2xx.c
strongarm.c
twl92230.c
instead of rtc_clock. This means that they're not completely
deterministic when using -icount or in the future qtest. A simple
search-and-replace would be okay I think. However they could also use a
notifier to update the timers whenever the rtc_clock jumped backwards
(see commit 17604da). If you are going to add the notifier I'll happily
leave the work to you; otherwise I'll post the search-and-replace patch.
