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).

3cb039fffa When you try to mount a file image, BFS now only sees the normalized path instead
of the one supplied to fs_mount() (but not the /dev/disk/virtual/... entry, as that
wouldn't be that clear to the user).

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.

dde52de872 * _NewReadLockInfo() can no longer crash in case the allocation failed.
* _ReadLock() will now fail with B_NO_MEMORY in case the ReadLockInfo couldn't
  be created.
* Note, due to a design bug, we cannot guarantee that a previous read lock
  can be reestablished after releasing a write lock in case of low memory.

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 :-)

77a08c68e8 Changed the way handlers for edge triggered interrupt are called: now, we
always call all handlers in this case, but we still try to return the correct
return code (ie. B_HANDLED_INTERRUPT and B_INVOKE_SCHEDULER).

99df69077c For level triggered interrupts, we now acknowledge the interrupt after having called
the interrupt handlers, not before (like we do for edge triggered ones).
This should prevent hardware from issuing a second interrupt when the software driver
is still busy handling the first.

5886ae3213 Finally (!) fixed that stupid bug that prevented at least some Pentium-M laptops to
work correctly when on power supply (ie. when running at full speed). Turns out we
misdetected a spurious interrupt on line 15 - we now ignore them completely which
seems to fix that problem.

11add5a5d7 First baby step towards a lockless get_memory_map(): vm_get_current_user_address_space()
no longer needs to lock address space hash table - that also makes the lookup much
faster, too (and a direct pointer is used instead of a hash lookup).

4827dbe47a Fixed a bug in the VFS that could cause BFS to corrupt an inode:
dir_remove() did not normalize the path, and thus, could forward a "." as
name for the removed directory - which BFS didn't catch because it assumed
our VFS would work correctly...

b2536cb5d6 Fixed bug #483:
* vfs_get_fs_node_from_path() now also work for absolute paths again (but
  still for relative ones from the volume root) - it just tests if the
  mount IDs fit, so it only returns successful if the path really is on
  the desired mount.
* the Disk Device Manager publish functions now call devfs_publish_*()
  correctly (by omitting the "/dev/" mount point).
* devfs_publish_partition() now accepts absolute device paths but relative
  partition paths.

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).

8645479b36 * cache_io() could insert a second page at the same position in the vm_cache
since it unlocked the cache while waiting on a busy page. Now, we're filling
  the pending request before unlocking the cache.
* Fixed the deadlock I mentioned in the last commit: if a page fault happens
  at the same time we're trying to read/write from/to a page, we no longer
  fight for the BFS inode lock, but eventually doing the job twice if needed.
  Will need to go over the "write modified" functions to make sure they are
  behaving as well.

675c19c9cf * fs_sync() and free_vnode() now use the file system's fsync() hook to write back
changes made to a file instead of directly using vm_cache_write_modified() -
  besides making the file system more independent from the file cache, this also
  works around a possible dead lock (that is to be fixed in a later commit).
* fs_sync() no longer uses vnodes from the mount's vnode list directly to write
  back the changes made to them, but gets them via ID instead - this makes sure
  the vnode is in a valid state and fixes a race condition with free_vnode().
