176f0604ed Continuing from the kernel debugger did not work on SMP machines, as SMP_MSG_CPU_HALT was
a one way ticket. It now works as expected.

f415aa28be * create_vnode() now panicks when it could not find the freshly created vnode
in the vnode hash; that's a bug in the FS that shouldn't be ignored that way.
* Minor cleanup.

aac3ed8c03 * Reverted r21199 (and therefore r21254) - it actually did work correctly initially,
see bug #1248.
* Closing a pipe now also removes it from the public namespace and marks it for
  deletion, and thus, there are no more left-overs after using a pipe.
* Minor cleanup.

77bf99deb0 fixed the way accept() works in regards to the cookie pointer. It is no longer visible to userspace, we pass the fd instead. Also renamed kernel's shutdown() to system_shutdown as it collides with Posix's shutdown().

01e7c0d868 You should not publish *every* node - at least not without releasing the ref if you don't need it.
This should allow you to actually unmount /pipe if you so desire.

bdf8a2e1e7 Added Haiku revision number to the kernel (same mechanism as used for
libroot). It's available in the kernel through the private
get_haiku_revision() and added to the kernel syslog output.

8ca5764554 * Implemented APM generic syscall API to query the current power status.
* PowerStatus is now using this API when compiled for Haiku.
* Note, I'm not sure why yet, but running PowerStatus in the background
  crashes at least my laptop after some time.

8cfe0be38e slab/cache: a couple more fixes.
- on CACHE_DURING_BOOT init benaphore count with 1.
 - account for allocated space on early_allocate_pages.
 - fixed slab position calculation in small slabs.
 - we can now init all allocator sizes early rather than later.

6e31ae98f9 some object cache / slab improvements.
- call the reclaimer callback when low on memory.
 - use the depot when on multi-cpu setups (for scalability).
 - fixed the amount of memory spent on slabs for very large objects.

6d1144bbca The thread context was destructed a bit too early: if a team was killed (or didn't
close all of its file descriptors), code outside of the core kernel would be executed
in the descriptor's close/free hooks.
Since the semaphore timeout code, and send_data()/receive_data() rely on the
thread being available in the thread hash, they wouldn't work anymore.
This fixes bug #1168. Thanks to Marcus for providing such a nice test case :-)

22428cc7b6 * More or less reverted my previous thread_yield() change: while this gives
threads with higher priorities a much better scheduling experience, it
  also creates a problem as soon as more than one higher priority thread
  waits on a resource held by a lower priority thread; the higher priority
  threads play ping-pong, and the lower priority thread doesn't get it's
  chance.
* Increased the probability of skipping a thread priority.
* I won't do any other changes on the scheduler, that's meianote's job now :-)

831486a2d3 Turn the assembly optimized memcpy (simple rep movsd) back on for x86. Had to hack around the make system a bit, and the result is pretty nasty, specifically due to the amount of places in the system where various targets poke their fingers into the libroot directory.
The solution is less than optimal, but should work for now.
