f33c8020e2 Removed debug/console.c, we no longer need it. frame_buffer_console_init() is now
called by debug_init_post_vm().
Since the availability of a blue screen specific getchar() is static anyway, there
is no need for the sBlueScreenGetChar variable (only the message "only serial input
available" gets lost, but since that is platform specific anyway...).
Hello blue screen! We now have an on-screen KDL, to be enabled by the kernel
setting "bluescreen", just like on BeOS.
The blue screen does not yet support any cursor actions or backspace, though (need
to grab some stuff from our console driver).

9a63135f7c Cleanup of the debug stuff, prepared for blue screen debugging.
kernel_debugger() didn't do enough before; panic() did all the work - but
since the former is a public function as well, I moved all the functionality
to it. Also fixed a possible buffer overrun in panic().
Renamed dbg_* to debug_*.
"serial_debug_port" setting did not ignore negative values.

6d352d08b3 Added an arch_get_caller() function that returns the caller of the calling function :-)
Minor cleanup.

b20667b35b {install|remove}_io_interrupt_handler() now correctly handle the B_NO_ENABLE_COUNTER flag.
Lots of cleanup:
- moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's
  described in the BeBook (although it's probably not really used that often :))
- int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone);
  it's now entirely handled in the arch/x86/ section.
- the io_vectors[] is now statically initialized, instead of allocated from the heap
- removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init()
  is now calling install_io_interrupt_handler() correctly instead
- introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only
  (though on x86, it also has ARCH_INTERRUPT_BASE == 0x20).
- changed the return type from {install|remove}_io_interrupt_handler() from "long" to
  "status_t"
- rearranged and cleaned the PIC initialization code, made the PIC code more prominent
- changed comments that talk about a non existing 8239 (the PIC chip is actually 8259)
- moved arch/x86/interrupts.h to the source directory, as it's not used outside
- added BeOS compatible interrupts_enabled() function, that should replace our
  equivalent (and private) are_interrupts_enabled()

f05e261fd7 The VM can now ask the platform dependent part if it supports a specified protection.
create_area() and friends should fail if it's not supported.

8e26b085e5 Fixed double fault handler. Personally I disclaim all responsiblity
for these changes. I was mostly just staring in amazement at the screen
while Axel and Thomas were discussing IA32 internals. A particularly
fascinating moment was when Thomas produced the cause of a bug we had
been trying to track down for hours off the top of his head (of course
iret behaves specially when the NT bit is set :-). His slowness must be
excused though, since he hadn't slept for more then 30 hours. ;-)

The code doesn't wholeheartedly deal with multi-processor machines yet.
Axel will certainly do some cleanup...

e5b0e0b5e3 Changed the set_segment_descriptor()'s usage of the limit/granularity
flag. Now, it will choose how to set the granularity by evaluating the
limit.
This call was actually already used this way in the kernel, so that
the TLS and TSS segments were much too large (harmless but incorrect).

9d06770cdc The iframe stack is now in a special structure iframe_stack.
Introduced a gBootFrameStack that is used until the first thread structure
is available - this allows stack crawls and useful register dumps during
early startup. Could also be solved differently by making sure there is
always a thread structure installed in %dr3 (ie. the boot thread would
get a static thread structure instead of a static iframe stack only).
This might be a better solution as i386_handle_trap() would no longer
need to check for an existing thread structure.

edb5566393 Fixed struct tss; there is no ss3/sp3.
Moved ptentry/pdentry to arch_vm_translation_map.c and renamed them to
page_table_entry and page_directory_entry.
Fixed a race condition that happened when memory was remapped (which
can currently happen because lock_memory() does not work correctly, and
there might be other conditions as well, like certain vm_store fault
handlers). Now, page table and directory entries are updated atomically.

85001a7cc6 * Fixed checking for DR6 bits after a debug exception (we were and'ing
with the bit number, not the respective mask).
* Added a small hack to allow single stepping to work in qemu.
  Apparently the BS bit in DR6 is not set when the debug exception
  is handled. So we always assume that a single step event occurred,
  when we couldn't recognize any other event, if the hack is enabled.

- removed the _struct suffix from certain structures
- fixed some return types

having allocated the TLS area.
Renamed arch_thread_initialize_kthread_stack() to arch_thread_init_kthread_stack()
to be more consistent.
Changed the parameters for arch_thread_enter_uspace() - it now gets a pointer
to the thread structure and takes the user stack pointer from there (which
might also be architectural different).
