it doesn't really do anything, it just passes the initial frame buffer
on to the app_server).
While it seems to work on real hardware (if you set the video mode to
640x480x32, app_server restriction), under Bochs, the app_server crashes.

Also changed readlink() to be POSIX compliant with those changes.
"ls -l" does now resolve links properly again (the new coreutils version outlined the problems).

create_area() and friends should fail if it's not supported.

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...

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).

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.

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.

the APM driver to see it at work).
The frame buffer console now creates such a boot item to give a potential
VESA driver access to the boot frame buffer configuration.

Probably only works under Haiku due to the new area flags.

Added a ToDo comment about the forgotten find_directory().

MenuItem::SetData() now asks for a const parameter.
The safemode menu options now set their MenuItem::Data() to the safemode option string.

instead B_KERNEL_PROTECTION and B_USER_PROTECTION.
Unlike before, B_USER_CLONEABLE_AREA is now only in B_KERNEL_AREA_FLAGS,
but no longer in B_KERNEL_PROTECTION. This fixes a couple of problems
when B_USER_CLONEABLE_AREA was defined without specifing read/write
access.
PAGE_PRESENT|MODIFIED|ACCESSED are in the same "namespace" as the
protection flags, and therefore, shouldn't overlap.

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.

* Added initialization function. Currently only need to init the
single step hack for qemu.
* Fixed a deadlock when the nub thread destroyed the debug info. It was
waiting for itself.
* Moved the filling in the origin info of the debug messages into
thread_hit_debug_event_internal(). No need for code duplication.
* Writing to user memory can now be partial. We also change the area
protection, if it wasn't writable. Necessary for setting software
breakpoints.

that we no longer need an initialize_after().
Put the architecture dependent hoard functions into the BPrivate namespace
as well. Minor cleanup.

Entirely implemented on top of the public <debugger.h> API, but more
convenient to use. Lives in a separate library libdebug.so.
