o Support for the front panel on the Indy. The panel work now as a

   user would expect it to work, like under IRIX with the exception
   that the machine doesn't freeze solid as long as the button is
   pressed.
 o Realtime clock driver (CONFIG_SGI_DS1286) for the Indy.  Includes
   /proc/rtc interface which tells you everything about your RTC which
   you never wanted to know.  You have to configure this driver into
   your kernel or you won't be able to set your RTC.
 o Some cleanup of the RTC interfaces in Linux, RTC does no longer mean
   PC-style RTC.  The userland interface definitions are now in
   <linux/rtc.h>.  We still need some more cleanup until we can enable
   several RTC drivers.
 o Virtual aliasing fixes for ptrace(2).
 o Add ptrace(2) interface definitions needed to build GDB to
   <asm/ptrace.h>.
 o Revert to some older routines, the newer optimized ones are buggy.
 o On panic the Indy LED will be blinking fast crying to the admin
   passing by [music from Rocky Horror show] ``fix me, fix me, fix
   me''.
 o On panic the power button will only reboot the machine, not power it
   down.  That's probably more what people want it to do.
 o Remove some old files.
 o Did I tell you that CVS is buggy?
