aaaad89244 Use int64 functions consistently 
Instead of manipulating the u64_t type directly, use the
ex64hi()/ex64lo()/make64() functions.

515e8d075f kernel: limit stacktrace depth to 50.

c9bfb13cdb Kernel keeps information about each cpu 
- kernel maintains a cpu_info array which contains various
  information about each cpu as filled when each cpu boots

- the information contains idetification, features etc.

9e01a83636 SMP - reduced TLB flushing 
- flush TLB of processes only if the page tables has been changed and
  the page tables of this process are already loaded on this cpu which
  means that there might be stale entries in TLB. Until now SMP was
  always flushing TLB to make sure everything is consistent.

40bfed28cd ACPI pci-to-pci bridges 
- every pci device which implements _PRT acpi method is considered to
  be a pci-to-pci bridge

- acpi driver constructs a hierarchy of pci-to-pci bridges

- when pci driver identifies a pci-to-pci bridge it tells acpi driver
  what is the primary and the secondary bus for this device

- when pci requests IRQ routing information from acpi, it passes the
  bus number too to be able to identify the device accurately

98c93e76d7 Zero no more hardwired as BSP apic id

  deliver the interrupts to BSP

a1eefc013e single shot timer interrupts fix 
- accidentaly this wasn't part of the SMP merge and the implementation
  remained uncomplete with the timer keeping ticking periodically

- APIC timer is set for a signel shot and restarted everytime it
  expires. This way we can keep the AP's trully idle

- the timer is restarted a little later before leaving to userspace

- LAPIC_TIMER_ICR is written before LAPIC_LVTTR so the newest value is
  used

ebbc730fc3 spurious and error interrupt apic handlers 
- fixed spurious and error interrupt handlers

- not to hog the system the warning isn't reported every time, just
  once every 100 times, similarly for the spurious PIC interrupts

26de8dd299 change SSIZE_MAX to INT_MAX instead of 32767. 
With this change, suggested by Gautam Tirumala, ports for pkgin and
pkg_install are cleaner and so easier to upstream.  Presumably other
ports will be smoother too.

There doesn't seem to be a reason SSIZE_MAX was so small to begin with.

98ddbffe6e dis386 - a disassembler for ack

e2570d9b1b vm: optimisation: avl tree for virtual regions 
- regions were preivous stored in a linked list, as 'normally'
    there are just 2 or 3 (text, data, stack), but that's slow
    if lots of regions are made with mmap()

  - measurable performance improvement with gcc and clang
