This allows cpus to be off-lined on 32-bit SMP powermacs. When a cpu is off-lined, it is put into sleep mode with interrupts disabled. It can be on-lined again by asserting its soft-reset pin, which is connected to a GPIO pin. With this I can off-line the second cpu in my dual G4 powermac, which means that I can then suspend the machine (the suspend/resume code refuses to suspend if more than one cpu is online, and making it cope with multiple cpus is surprisingly messy).

This is a patch that I have had in my tree for ages. If init causes an exception that raises a signal, such as a SIGSEGV, SIGILL or SIGFPE, and it hasn't registered a handler for it, we don't deliver the signal, since init doesn't get any signals that it doesn't have a handler for. But that means that we just return to userland and generate the same exception again immediately. With this patch we print a message and kill init in this situation. This is very useful when you have a bug in the kernel that means that init doesn't get as far as executing its first instruction. :) Without this patch the system hangs when it gets to starting the userland init; with it you at least get a message giving you a clue about what has gone wrong.

Use schedule_timeout_interruptible() instead of set_current_state()/schedule_timeout() to reduce kernel size. Also use human-time to jiffies units conversion functions rather than direct HZ division to avoid rounding issues. Signed-off-by:

Clarify the human-time units to jiffies conversion functions by using the constants in time.h. This makes many of the subsequent patches direct copies of the current code. Signed-off-by:

Remove S4BIOS support. It is pretty useless, and only ever worked for _me_ once. (I do not think anyone else ever tried it). It was in feature-removal for a long time, and it should have been removed before. Signed-off-by:

Use msleep() or msleep_interruptible() [as appropriate] instead of schedule_timeout() to gurantee the task delays as expected. As a result changed the units of the timeout variable from jiffies to msecs. Signed-off-by:
