Axel Dörfler 51a3c450be The short story: we now have MTRR support on Intel and AMD CPUs (the latter 
has not yet been tested, though - I'll do this after this commit):
* Removed the arch_memory_type stuff from vm_area; since there are only 8 memory
  ranges on x86, it's simply overkill. The MTRR code now remembers the area ID
  and finds the MTRR that way (it could also iterate over the existing MTRRs).
* Introduced some post_modules() init functions.
* If the other x86 CPUs out there don't differ a lot, MTRR functionality might
  be put back into the kernel.
* x86_write_msr() was broken, it wrote the 64 bit number with the 32 bit words
  switched - it took me some time (and lots of #GPs) to figure that one out.
* Removed the macro read_ebp() and introduced a function x86_read_ebp()
  (it's not really a time critical call).
* Followed the Intel docs on how to change MTRRs (symmetrically on all CPUs
  with caches turned off).
* Asking for memory types will automatically change the requested length to
  a power of two - note that BeOS seems to behave in the same, although that's
  not really very clean.
* fixed MTRRs are ignored for now - we should make sure at least, though,
  that they are identical on all CPUs (or turn them off, even though I'd
  prefer the BIOS stuff to be uncacheable, which we don't enforce yet, though).
