[PATCH] misc. kernel preemption bits
Misc. kernel preemption-related bits. Specifically,
- update to Documentation/preempt-locking.txt (me)
- preempt-safe arch/i386/kernel/ioport.c :: sys_ioperm()
(George Anzinger)
- remove "kernel_lock()" cruft in include/linux/smp.h
(Andrew Morton)
- we have a debug check in preempt_schedule that, even
on detecting a schedule with irqs disabled, still goes
ahead and reschedules. We should return. (me)
- preempt-safe net/core/dev.c :: netif_rx() (George Anzinger)
