had the cache_ref locked, it also locked two refs in the wrong order (bottom-up);
there was even a TODO item for this...

* "sc"/"where"/"bt" now prints the area where the function of the stack frame
is located in case there is no other information (using the above function).

* even worse, in case of fork(), it was never initialized.

Pending DPCs at queue death time are now called too, to avoid possible leaks.
Meanwhile, queue_dpc() will refuse to add another DPC and returns B_CANCELLED.

two cache_refs - it needs to count the consumers of the lower cache to find
its actual number of references; the upper cache could still be in use by
someone else.
* There were several locking bugs in the VM code; since cache_ref::cache can
change, we must not access it without having the cache_ref locked.
* As a result, map_backing_store() now requires you to have the lock of the
store's cache_ref held.
* And therefore, some functions in vm_cache.c must no longer lock the cache_ref
on their own, but require the caller to have it locked already.
* Added the -s option to the cache/cache_ref KDL commands: it will only print
the requested structure, and not its counterpart (useful if accessing one
structure results in a page fault, as was possible previously).

without any argument specifier, and a(void); != a(); in C.
* Added the VMware graphics driver to the image.

Made the following changes from the version I got from Eric:
* made BppForSpace() in DriverInterface.h inline to remove some warnings
* renamed driver source files to lower case.
* removed Be Inc. copyright from kernel driver as I couldn't see anything coming
from Be Inc. there - correct me if I was wrong, Eric.
* Minor other changes like added missing header guards.
* The README provided in the main directory is only included in the accelerant
directory.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19793 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Updated coreutils.rdef to follow the same style as all other rdef files (or at least
most of them).

waiting for in case it was interrupted; but that could easily lead the thread_exit()
function to access invalid memory (and thus, crash the kernel): since we could not
remove our death entry from the thread, we have to make sure the thread (which might
still run even if not in the thread hash anymore) will access our death entry as
long as it is valid. IOW we must wait for the thread to delete its exit semaphore,
even if we were interrupted before.

* Fixed dumping the area list of a cache I broke with the previous commit.
* Minor cleanup.

(you can still use both commands, but you'll see always the same output).
* The cache_ref's area list now also prints the owner of the area.
* Added "-p" option to "cache"/"cache_ref" that will show the pages of the cache; if you
omit it, it will now only present you a page counter.
* Nicer output for the commands above.
* Added "dl" to display memory in 64 bit values.

* send_signal_etc() (among others) used team::main_thread in an unsafe way; it is
possible for a team to be part of the team list and a group without having
a main thread very early in its creation process.
* Replaced most occurences of team->main_thread->id with team->id since the team
always inherits the ID of its main thread in Haiku for quite some time now.
* Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19781 a95241bf-73f2-0310-859d-f6bbb57e9c96
the userland stack in an unsafe way - moved that stuff to arch_thread_enter_userspace(), too.

* This is now used for userland stack - they now always pre-commit two pages, enough
to initialize TLS and copy the user-thread-exit stub to that area.
* Minor cleanup.

turned off - accessing userland memory. Now, arch_thread_enter_userspace() does that
job, and as a result, may also fail.
* dump_thread() now directly prints the info of the current thread when used without
argument (rather than iterating the thread list to look for the current thread).
* If arch_thread_init_tls() fails upon thread creation, the function will now return
an error.

them to commit substantially less memory (we we're committing about 40 MB (!) too much
after a complete system boot). This means you'll run out of memory less likely now.
* fill_area_info() no longer filters out kernel protection flags - we may want to keep
filtering them when called from userland, though, dunno.
* Added new debugger command "avail" which shows how much memory has been committed, and
how much is regarded as free space.

another test that doesn't work on BeOS, dunno why, but who cares...).

Fixed most obvious issues, as reported by Marcus and Axel.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19765 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented a fibo_fork which uses fork() instead.
* Both tests can pretty easily let the kernel crash!

Until, it's obvioulsy not ready for prime time: using it to queue AcpiOsExecute() event/method callbacks...

to other kernel components.
* wait_for_thread_etc() will now search the team's death entries in case the
thread is already gone; also resume_thread() is now done later, and its return
code will no longer matter (as we already have our death entry, no matter if
the thread is gone now or not).
* The fibo_load_image test now works as expected (only tested with low numbers
yet, though - the mean testing comes later (first comes functionality) :-))
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19758 a95241bf-73f2-0310-859d-f6bbb57e9c96
due to problems with wait_for_thread().
* Minor cleanup to the Jamfile.
