e87d29171f SMP - Compiles for both single and multi processor again 
- this patch adds various fixes as some of the previous patches break
  compilations without CONFIG_SMP being set

311f145bc7 SMP - Balancing run queues for SMP 
- it preempts running processes though :( this is not the final
  solution

06b6e5624a SMP - Changed prototype of sys_schedule() 
- sys_schedule can change only selected values, -1 means that the
  current value should be kept unchanged. For instance we mostly want
  to change the scheduling quantum and priority but we want to keep
  the process at the current cpu

- RS can hand off its processes to scheduler

- service can read the destination cpu from system.conf

- RS can pass the information farther

1e273f640e SMP - Scheduler can assign process to a cpu 
- machine information contains the number of cpus and the bsp id

- a dummy SMP scheduler which keeps all system processes on BSP and
  all other process on APs. The scheduler remembers how many processes
  are assigned to each CPU and always picks the one with the least
  processes for a new process.

13ef7f1f38 Prepare VFS to support back calls from PFS. For security reasons and to support 
file descriptor passing, PFS does some back calls to VFS. For example, to
verify the validity of a path provided by a process and to tell VFS it must
copy file descriptors from one process to another.

Thomas Veerman
6bbcab3ec4 Clean up MFS a bit: 
- Remove unused includes.
 - Add include guards to headers.
 - Use unsigned variables in case they're never going to hold a negative
   value. This causes GCC's complaints to disappear and should make flexelint
   a lot happier, too.
 - Make functions private when they're used only within a module.
 - Remove unused variables.
 - Add casts where appropriate.
