bef4e1fc77 * each device manager node has now an autogenerated identifier
* added a generic syscall for device_manager
it enables to iterate the device manager tree from userland
* the listdev tool is now using it: it's still incomplete as it only dumps nodes and attributes

a1939ee423 Modified the pxe_ia32 stage 1 loader to load stage 2 at the same address as bios_ia32 stage 1 does.
This allowes to actually execute the boot loader now. 
Need to use Ingo's remote_disk_server now for booting.

d593e74a27 First steps towards being able of collapse vm_cache objects after forking:
* a vm_cache now maintains a list of its "consumer" caches.
* introduced to new functions that add/remove consumer to a cache (instead
  of only maintaining the vm_cache::source field).
* fixed the incorrect reference counting when doing copy-on-write; we kept
  one ref too many of the lower cache.
* minor cleanup.

7f4e6824df Added a private call to get the dependencies of a loaded image. This will be used
to determine linkage of libnet.so vs. libsocket.so/libbind.so in the libnetwork.so.

02cc779b7d Moved datastore implementation into net_buffer.cpp - there is no reason to clobber the kernel with it.
This also fixes the issue of exporting a C++ API from the kernel.

d9766fe30b * Changed team_get_process_group_locked() to have a session parameter instead
of a team to avoid confusion. It now also accepts a NULL session pointer in
  which case the actual group's session doesn't matter.
* Fixed the race condition in send_signal_etc() that could allow accessing an
  invalid team pointer.
* Jerome's earlier change already fixed bug #841, and this also fixed bug #855.

d564275ba7 added disk systems rescan to DiskDeviceManager, and called it in the post init phase
the next step would be to rescan the partition tree with a job to recognize unrecognized partitions (asynchronously ?)

be0e738496 * send_signal_etc() now handles a pid_t of -1 specially, but not yet really correct
(that was part of the problem of bug #702).
* Fixed send_signal_etc() when you called it with a pid_t of zero: the signals should
  go to all teams in the calling team's group, not only to the team (for -1, we do
  the same for now).
* Made team_get_process_group_locked() public, and rewrote send_signal_etc() to use
  it.

6961cdf6f2 Process groups are no longer searched via their team/session, but by using a separate
hash. This also allows them to stay valid after the group leader died when there are
other teams left in it. This closes bug #1.

2b6a368811 wait_for_child() could eventually hang until another team exited (or forever if
it waited for a specific child), as B_RELEASE_ALL opened up a race condition between
looking for an existing death entry, and waiting for the dead children semaphore.
Now we're counting all waiting threads for teams and groups separately.

inserts the item before, and not after the given element (that's probably
  what you expected anyway).

d51ce54011 * Added the opportunity to add temporary debug interrupt handlers for
arch dependent code (they will be removed as soon as someone else
  asks for these interrupt lines).
* Added an interrupt driven keyboard handler to the kernel that uses
  this technique. As a result, you can now press F12 to enter the kernel
  debugger before the input_server has been started, and Control-Alt-Delete
  should reboot the system (actually I did not test the latter yet).

2bbc6df8dc * The kernel now remembers the signal that killed a thread (if it was killed).
* As suggested by Korli, the signal is now encoded in the "reason" field of
  wait_for_child().
* waitpid() now sets the status passed in so that the signal can be read out
  (but it still doesn't do it's full job).

65bd831cbb * KDiskDeviceManager::_ScanPartition() can now run synchronously (and execute the
scan job in the calling thread).
* KDiskDeviceManager::InitialDeviceScan() now runs synchronously, so that
  get_boot_partitions() doesn't need to do this ugly wait hack.
* KDiskDeviceManager::CreateFileDevice() can now run synchronously as well, which
  fixes a deadlock in fs_mount() - note, mounting file devices still doesn't work,
  though as Haiku's BFS doesn't allow this right now.

573c4336a3 Implemented quite a hack to solve the lockless get_memory_map() problem (bug #349):
when called with interrupts turned off, get_memory_map() will now call the new
vm_translation_map_ops::query_interrupt() call.
Under PPC, this is trivial (at least right now), but on x86 we need to make sure
we have access to the page table entry, ie. we need to create an area that points
to its own page table entry, so that we can map in the page table entry containing
the address we're looking for. It's not really nice, feel free to come up with
a cleaner solution :-)

97e069713b Added a "reenter" parameter to the {read|write}_pages() functions to give file
systems a chance to know if they have locked already.
This fixes a locking problem in BFS where one thread tried to acquire two read
locks (where someone else trying to acquire a write lock would have caused a
dead lock).

of that list.

  directly.
* create_sem_etc() now calls the above function in case there are no semaphores
  available anymore; this usually frees up to 2 semaphores per node (one from
  the cache if there is a file cache attached, and eventually one from the
  file system).
