Tomas Hruby 42c13951a7 APIC disabled if CPU lacks TSC 
- we cannot calibrate local APIC timer in such a case

- fixes possible uninitialized variable problem during calibration if no TSC

Kees van Reeuwijk ad4c0ff698 Fixed a bug in apic.c that broke lapic_stop_timer(). 
Fixed bugs in liveupdate.c that rendered load_state_info() meaningless.
More informative error message in do_config() in service.c.

Kees van Reeuwijk d8f3af3672 Fixed a typing bug. 
More explicit type conversion from virual to physical bytes.
Bracket negative #defines for extra paranoia.
Added a forgotten 'void' to a function.

Tomas Hruby 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
