e1c6140eaa mmlr + bonefish:
* Add optional stack trace capturing for slab memory manager tracing.
* Add allocation tracking for the slab allocator (enabled via
  SLAB_ALLOCATION_TRACKING). The allocation tracking requires tracing
  with stack traces to be enabled for object caches and/or the memory
  manager.
  - Add class AllocationTrackingInfo that associates an allocation with
    its respective tracing entry. The structure is added to the end of
    an allocation done by the memory manager. For the object caches
    there's a separate array for each slab.
  - Add code range markers to the slab code, so that the first caller
    into the slab code can be retrieved from the stack traces.
  - Add KDL command "allocations_per_caller" that lists all allocations
    summarized by caller.
* Move debug definitions from slab_private.h to slab_debug.h.

72156a402f bonefish+mmlr:
* Introduce "paranoid" malloc/free into the slab allocator (initializing
  allocated memory to 0xcc and setting freed memory to 0xdeadbeef).
* Allow for optional stack traces for slab object cache tracing.

b4e5e49823 MemoryManager:
* Added support to do larger raw allocations (up to one large chunk (128 pages))
  in the slab areas. For an even larger allocation an area is created (haven't
  seen that happen yet, though).
* Added kernel tracing (SLAB_MEMORY_MANAGER_TRACING).
* _FreeArea(): Copy and paste bug: The meta chunks of the to be freed area
  would be added to the free lists instead of being removed from them. This
  would corrupt the lists and also lead to all kinds of misuse of meta chunks.

object caches:
* Implemented CACHE_ALIGN_ON_SIZE. It is no longer set for all small object
  caches, but the block allocator sets it on all power of two size caches.
* object_cache_reserve_internal(): Detect recursion and don't wait in such a
  case. The function could deadlock itself, since
  HashedObjectCache::CreateSlab() does allocate memory, thus potentially
  reentering.
* object_cache_low_memory():
  - I missed some returns when reworking that one in r35254, so the function
    might stop early and also leave the cache in maintenance mode, which would
    cause it to be ignored by object cache resizer and low memory handler from
    that point on.
  - Since ReturnSlab() potentially unlocks, the conditions weren't quite correct
    and too many slabs could be freed.
  - Simplified things a bit.
* object_cache_alloc(): Since object_cache_reserve_internal() does potentially
  unlock the cache, the situation might have changed and their might not be an
  empty slab available, but a partial one. The function would crash.
* Renamed the object cache tracing variable to SLAB_OBJECT_CACHE_TRACING.
* Renamed debugger command "cache_info" to "slab_cache" to avoid confusion with
  the VMCache commands.
* ObjectCache::usage was not maintained anymore since I introduced the
  MemoryManager. object_cache_get_usage() would thus always return 0 and the
  block cache would not be considered cached memory. This was only of
  informational relevance, though.

slab allocator misc.:
* Disable the object depots of block allocator caches for object sizes > 2 KB.
  Allocations of those sizes aren't so common that the object depots yield any
  benefit.
* The slab allocator is now fully self-sufficient. It allocates its bootstrap
  memory from the MemoryManager, and the hash tables for HashedObjectCaches use
  the block allocator instead of the heap, now.
* Added option to use the slab allocator for malloc() and friends
  (USE_SLAB_ALLOCATOR_FOR_MALLOC). Currently disabled. Works in principle and
  has virtually no lock contention. Handling for low memory situations is yet
  missing, though.
* Improved the output of some debugger commands.

a38f850360 * arch_debug_get_stack_trace():
- Replaced the "userOnly" parameter by a "flags" parameter, that allows to
    specify kernel and userland stack traces individually.
  - x86, m68k: Don't always skip the first frame as that prevents the caller
    from being able to record its own address.
* capture_tracing_stack_trace(): Replaced the "userOnly" parameter by
  "kernelOnly", since one is probably always interested in the kernel stack
  trace, but might not want the userland stack trace.
* Added stack trace support for VM cache kernel tracing.

f28dd36b82 * The alphabet is obviously hard, moved some tracing defines at their
(hopefully) correct place.
* It seems to be even harder to understand basic locking primitives: when you
  think about it, it shouldn't surprise you that conditional variables never
  return B_WOULD_BLOCK. This fixes gdb again.
* Added tracing support to the ports subsystem.
* get_port_message() will now resize the port heap if needed (but will also
  take timeouts into account while doing so, more or less). The initial port
  space is 4MB (as before), the growth rate is the same, and the system wide
  limit is arbitrarily set to 64 MB (all swappable). A team limit has been set
  to 8 MB, but is not enforced yet. Since ports are using up address space in
  the kernel, those seems to be proper limits.
* This also fixes a strange, and rare lockup where the mouse cursor would still
  move, but everything else would basically hang, but look perfectly normal from
  KDL on the first look. As recently happened on Brecht's laptop, and debugged
  by mmlr and me: the cbuf space got used up when lots of windows wanted to
  redraw after a workspace switch. The app_server wouldn't answer anymore to
  client requests, but thought it would have done so, as LinkSender::Flush()
  doesn't care if it got a B_NO_MEMORY (the ports will now block until memory
  is available if possible, so that should not be a problem anymore).
* Improved "port" KDL command, it now also prints the messages in the port.

b2cfc2b1c0 * Added kernel tracing for page faults.
* vm_clone_area() does now set the B_SHARED_AREA flag on both the source
  and the cloned area. This is necessary, since it would no longer be
  guaranteed that areas are backed by leaf caches only (after
  fork()ing), which doesn't work with our cache merging strategy.
  Fixes #2605.

b3d6c12dbf * Fixed kernel tracing for gcc 4. The ABI changed in a way that isn't
compatible with what our code assumed (pointers to objects of
  TraceEntry and its POD base class trace_entry aren't identical
  anymore).
* Added optional stack traces for ktrace_printf() output in the kernel.

8e8edffce7 * Fixed at least the "dd" part of bug #2148: the second double indirect array
block would be incorrectly addressed when allocating a stream - this could
  cause random blocks to be overwritten, and therefore could cause many sorts
  of problems.
* Moved BFS_TRACING macro to the tracing_config.h file, and let it follow the
  new semantics of those other macros in there.

  what one usually wants.

* Added "mode" parameter to set_paranoia_check(), which specifies
  whether the check is supposed to already exist/not exist yet. This
  allows for, as it turns out, very useful additional tests. Added
  {ADD,UPDATE}_PARANOIA_CHECK macros that imply the used "mode"
  parameter.
* PARANOIA_SLOT_COUNT was accidentally redefined in the source file.
* Fixed remove_paranoia_check(). It didn't remove anything.

071f9c3aa2 Build configurations shouldn't be done in svn controlled files, so I
finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.
