I added some code to speed up context switching. Before, the woken-up process
needed to do a complete page table walk in order to update its address space
with any changes that had occurred when it was asleep.
Now, proc->mm->segments remembers those changes, and on most wakeups, this
list can be used to do the updates.
I also made /proc/interrupts contain some minimal useful information.
