f720882cf0 Rework the physical<->machine memory mapping: offset physical addresses 
by 0x100000 (above the I/O Memory "hole") leaving all physical addresses
below unused, don't perform phys<->mach mapping for addresses below 0x100000
or beyond the real hardware's physical memory.

-> /dev/mem works now as expected and X works in domain0.

ea5ec0212d add kernel part of concurrency support for SA on MP systems 
- move per VP data into struct sadata_vp referenced from l->l_savp
  * VP id
  * lock on VP data
  * LWP on VP
  * recently blocked LWP on VP
  * queue of LWPs woken which ran on this VP before sleep
  * faultaddr
  * LWP cache for upcalls
  * upcall queue
- add current concurrency and requested concurrency variables
- make process exit run LWP on all VPs
- make signal delivery consider all VPs
- make timer events consider all VPs
- add sa_newsavp to allocate new sadata_vp structure
- add sa_increaseconcurrency to prepare new VP
- make sys_sa_setconcurrency request new VP or wakeup idle VP
- make sa_yield lower current concurrency
- set sa_cpu = VP id in upcalls
- maintain cached LWPs per VP
