611376fef7 x86: Let each CPU have its own GDT 2013-12-17 03:57:20 +01:00

b5c9d24abc Implemented threading for x86_64.
* Thread creation and switching is working fine, however threads do not yet
  get interrupted because I've not implemented hardware interrupt handling
  yet (I'll do that next).
* I've made some changes to struct iframe: I've removed the e/r prefixes
  from the member names for both 32/64, so now they're just named ip, ax,
  bp, etc. This makes it easier to write code that works with both 32/64
  without having to deal with different iframe member names.

4304bb9894 Added arch_cpu.cpp to the x86_64 build.
* Some things are currently ifndef'd out completely for x86_64 because
  they aren't implemented, there's a few other ifdef's to handle x86_64
  differences but most of the code works unchanged.
* Renamed some i386_* functions to x86_*.
* Added a temporary method for setting the current thread on x86_64
  (a global variable, not SMP safe). This will be changed to be done
  via the GS segment but I've not implemented that yet.

0897e314b7 Merged x86_64 headers into x86 headers.
Not many changes seeing as there's not much x86_64 stuff done yet. Small
differences are handled with ifdefs, large differences (descriptors.h,
struct iframe) have separate headers under arch/x86/32 and arch/x86/64.
