Add a test to make this happen (triggers a vm panic before this commit).

f0db9bb328 - map in as much memory as is necessary in 4MB chunks to 
let boot processes run with segments
 - allow segment-only processes to fork() by copying them
   and giving them an identity page table

51065a1b47 Cooments to warn not to use certains instructions 
- gas2ack cannot handle all variants of some instructions. Until this issues is
  addressed, this patch places a big warning where appropriate. This code is not
  supposed to change frequently.

7c0cdc61bc fix for race condition - IRQ can happen between clearing the endpoint 
of the handling process and before removing the hook. The handler function
will panic then.

fe7b2f1652 RS fixes: 
- fix resource leak (PCI ACLs) when child fails right after exec
- fix resource leak (memory) when child exec fails at all
- fix race condition setting VM call privileges for new child
- make dev_execve() return a proper result, and check this result
- remove RS_EXECFAILED, as it should behave exactly like RS_EXITING
- add more clarifying comments about starting servers

8a44a44cb9 Local APIC 
- local APIC timer used as the source of time

- PIC is still used as the hw interrupt controller as we don't have
  enough info without ACPI or MPS to set up IO APICs

- remapping of APIC when switching paging on, uses the new mechanism
  to tell VM what phys areas to map in kernel's virtual space

- one more step to SMP

based on code by Arun C.

cb9faaebfd No need for a special idle queue 
- as the idle task is never placed on any run queue, we don't need any special
  idle queue.

- one more queue available for user processes

ad4dcaab71 Idle task never runs 
- idle task becomes a pseudo task which is never scheduled. It is never put on
  any run queue and never enters userspace. An entry for this task still remains
  in the process table for time accounting

- Instead of panicing if there is not process to schedule, pick_proc() returns
  NULL which is a signal to put the cpu in an idle state and set everything in
  such a way that after receiving and interrupt it looks like idle task was
  preempted

- idle task is set non-preemptible to avoid handling in the timer interrupt code
  which make userspace scheduling simpler as idle task does not need to be
  handled as a special case.

37a7e1b76b Use of isemptyp() macro instead of testing RTS_SLOT_FREE flag

  set. This change unifies the test
