The reference count fix merged isn't fully bug free. It doesn't leak now, but instead it crashes due to looking at freed memory. So for now, lets reverse the change and I'll fix it for real next week. Signed-off-by:

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:
