The real time clock only needs 8 bytes, but rtc.c is reserving 10h bytes.
This conflicts with zt55XX cpci compute blades that use one of those
extra bytes (port 79h) to control a watchdog timer.
I raised this issue before on LKML and everyone seemed to be ok with changing
the extent of rtc.c to 0x8:

I have been running the following patch on three of my Linux servers for
the last couple of weeks with no problems, and two of those server were
testing the watchdog timer that uses port 79h.
Please apply this patch.
