* [PATCH] ppc64: replace schedule_timeout() with msleep_interruptible()Nishanth Aravamudan2005-09-053-22/+12
| | | | | | | | | | | | | | | | | Use msleep_interruptible() instead of schedule_timeout() in ppc64-specific code to cleanup/simplify the sleeping logic. Change the units of the parameter of do_event_scan_all_cpus() to milliseconds from jiffies. The return value of rtas_extended_busy_delay_time() was incorrectly being used as a jiffies value (it is actually milliseconds), which is fixed by using the value as a parameter to msleep_interruptible(). Also, use rtas_extended_busy_delay_time() in another case where similar logic is duplicated.

* [PATCH] ppc32: Added support for the Book-E style Watchdog TimerKumar Gala2005-09-0510-27/+270
| | | | | | | | | | | | | | | | | | | | | | | | | | | PowerPC 40x and Book-E processors support a watchdog timer at the processor core level. The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.
