Saarett 03b3086327 Free pgdir in setupkvm in case of mappages failure
There is a potential memory leak when mappages() fails inside setupkvm().
A call to freevm() is added in this case so as to reclaim the lost mapping pages.

Frans Kaashoek ed396c068b Eliminate code for gs trick to track per-cpu state. We rely on lapiccpunum()
to find a per-cpu id with which we locate a cpu's cpu struct.

Frans Kaashoek fbb4c09444 Read curproc from cpu structure, but be careful because after a schedule event
myproc() points to a different thread.

   myproc();
   sched();
   myproc();  // this proc maybe different than the one before sched

Thus, in a function that operates on one thread better to retrieve the
current process once at the start of the function.
