45bd7bb3db Removed unnecessary inclusions of <boot/kernel_args.h> in private kernel
headers and respectively added includes in source files.

badc7b674e yet another fix for #1018, which has at this point blossomed into a reorg of how AP cpus are initialized.
the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the 
current thread, but that has a race condition that would require an int disable, etc.

dcdc4f4b43 pulled over some stuff from newos:
at boot, per cpu, detect the cpu, pull down all the relevant cpuid bits and
save them into the per-cpu structure. Changed most of the code scattered here
and there that reads the cpuid to use a new api, x86_check_feature, which looks
at the saved bits.
Also changed the system_info stuff to read from these bits.
While i was at it, refreshed all the bits to be current.

e0e9a3e69f * We now support the global page feature of x86 processors that prevents
kernel TLBs from being flushed on context switch.
* new arch_cpu_user_TLB_invalidate() that now does what arch_cpu_global_TLB_invalidate()
  did before.
* arch_cpu_global_TLB_invalidate() will now flush all TLBs, even those from the
  kernel.
* some cleanups.

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).

b0d8e689ac Renamed some more init2 routines to init_post_vm() to make it clearer when
and why they are called.
Introduced a cpu_init_post_vm() that will now call arch_init_post_vm() instead
of letting main() doing it.
Fixed some return types (mostly from int to status_t).

afad65ded7 Replaced all remaining PAGE_SIZE with B_PAGE_SIZE, addr with addr_t.
Removed the definition of PAGE_SIZE and addr.

c17f45d123 Some header cleanups.
Renamed dbg_save_registers() to arch_...() since it's arch dependent.
Removed unnecessary dependencies to stage2.h.

11fe0cb8de Added prototypes for the sys_/user_ attribute calls.
Changed the file_descriptor structure (more status_t, name removed).
Changed "extern inline" to "static inline" in thread.h/arch_thread.h as those
also work with -O0 -g.
Added prototypes for [arch_cpu_]user_strlcpy().
