e65c400299 * Replaced the vm_page_allocate_page*() "pageState" parameter by a more
general "flags" parameter. It encodes the target state of the page -- so
  that the page isn't unnecessarily put in the wrong page queue first -- a
  flag whether the page should be cleared, and one to indicate whether the
  page should be marked busy.
* Added page state PAGE_STATE_CACHED. Not used yet.

72382fa629 * Removed the page state PAGE_STATE_BUSY and instead introduced a vm_page::busy
flag. The obvious advantage is that one can still see what state a page is in
  and even move it between states while being marked busy.
* Removed the vm_page::is_dummy flag. Instead we mark marker pages busy, which
  in all cases has the same effect. Introduced a vm_page_is_dummy() that can
  still check whether a given page is a dummy page.
* vm_page_unreserve_pages(): Before adding to the system reserve make sure
  sUnreservedFreePages is non-negative. Otherwise we'd make nonexisting pages
  available for allocation. steal_pages() still has the same problem and it
  can't be solved that easily.
* map_page(): No longer changes the page state/mark the page unbusy. That's the
  caller's responsibility.

e054bfbf08 * Added missing IPv6 defines and in6addr_any, in6addr_loopback exports.
* This should get most IPv6 applications to link (they just can't open IPv6
  sockets yet, as the protocol is missing).

deee8524b7 * Introduced {malloc,memalign,free}_etc() which take an additional "flags"
argument. They replace the previous special-purpose allocation functions
  (malloc_nogrow(), vip_io_request_malloc()).
* Moved the I/O VIP heap to heap.cpp accordingly.
* Added quite a bit of passing around of allocation flags in the VM,
  particularly in the VM*AddressSpace classes.
* Fixed IOBuffer::GetNextVirtualVec(): It was ignoring the VIP flag and always
  allocated on the normal heap.

cff6e9e406 * The system now holds back a small reserve of committable memory and pages. The
memory and page reservation functions have a new "priority" parameter that
  indicates how deep the function may tap into that reserve. The currently
  existing priority levels are "user", "system", and "VIP". The idea is that
  user programs should never be able to cause a state that gets the kernel into
  trouble due to heavy battling for memory. The "VIP" level (not really used
  yet) is intended for allocations that are required to free memory eventually
  (in the page writer). More levels are thinkable in the future, like "user real
  time" or "user system server".
* Added "priority" parameters to several VMCache methods.
* Replaced the map_backing_store() "unmapAddressRange" parameter by a "flags"
  parameter.
* Added area creation flag CREATE_AREA_PRIORITY_VIP and slab allocator flag
  CACHE_PRIORITY_VIP indicating the importance of the request.
* Changed most code to pass the right priorities/flags.

These changes already significantly improve the behavior in low memory
situations. I've tested a bit with 64 MB (virtual) RAM and, while not
particularly fast and responsive, the system remains at least usable under high
memory pressure.
As a side effect the slab allocator can now be used as general memory allocator.
Not done by default yet, though.

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.

8d1316fd23 Replaced CACHE_DONT_SLEEP by two new flags CACHE_DONT_WAIT_FOR_MEMORY and
CACHE_DONT_LOCK_KERNEL_SPACE. If the former is given, the slab memory manager
does not wait when reserving memory or pages. The latter prevents area
operations. The new flags add a bit of flexibility. E.g. when allocating page
mapping objects for userland areas CACHE_DONT_WAIT_FOR_MEMORY is sufficient,
i.e. the allocation will succeed as long as pages are available.

86c794e5c1 slab allocator:
* Implemented a more elaborated raw memory allocation backend (MemoryManager).
  We allocate 8 MB areas whose pages we allocate and map when needed. An area is
  divided into equally-sized chunks which form the basic units of allocation. We
  have areas with three possible chunk sizes (small, medium, large), which is
  basically what the ObjectCache implementations were using anyway.
* Added "uint32 flags" parameter to several of the slab allocator's object
  cache and object depot functions. E.g. object_depot_store() potentially wants
  to allocate memory for a magazine. But also in pure freeing functions it
  might eventually become useful to have those flags, since they could end up
  deleting an area, which might not be allowable in all situations. We should
  introduce specific flags to indicate that.
* Reworked the block allocator. Since the MemoryManager allocates block-aligned
  areas, maintains a hash table for lookup, and maps chunks to object caches,
  we can quickly find out which object cache a to be freed allocation belongs
  to and thus don't need the boundary tags anymore.
* Reworked the slab boot strap process. We allocate from the initial area only
  when really necessary, i.e. when the object cache for the respective
  allocation size has not been created yet. A single page is thus sufficient.

other:
* vm_allocate_early(): Added boolean "blockAlign" parameter. If true, the
  semantics is the same as for B_ANY_KERNEL_BLOCK_ADDRESS.
* Use an object cache for page mappings. This significantly reduces the
  contention on the heap bin locks.

5570fd11c0 - Locale kit : made the language class live. It now uses ICU as a backend as expected
- Some changes in the locale roster to allow instanciating a language
- Locale preflet : use this new API instead of directly calling ICU
Side effect : all languages in Locale window are now displayed in the current locale. It makes more sense as otherwise the list would be unsortable. However it can get annoying if you mistakenly set a strange language as default.

453a2bdd18 Replaced the locking strategy (formerly a recursive lock for the depot and
one for each per CPU store):
* The depot is now protected by a R/W lock combined with a spinlock. It is
  required to either hold read lock + spinlock or just the write lock.
* When accessing the per CPU stores we only need to acquire the read lock
  and disable interrupts. When switching magazines with the depot we
  additionally get the spinlock.
* When allocating a new magazine we do completely unlock.

5662ae4585 Changed the team shutdown process a bit:
* The threads beside the main thread are killed earlier now (in the new
  team_shutdown_team()), before removing the team from the team hash and from
  its process group. This fixes #5296.
* Use a condition variable instead of a semaphore to wait for the non-main
  threads to die. We notify the condition right after a thread has left the
  team. The semaphore was released by the undertaker.

6379e53e2d vm_page no longer points directly to its containing cache, but rather to a
VMCacheRef object which points to the cache. This allows to optimize
VMCache::MoveAllPages(), since it no longer needs to iterate over all pages
to adjust their cache pointer. It can simple swap the cache refs of the two
caches instead.

Reduces the total -j8 Haiku image build time only marginally. The kernel time
drops almost 10%, though.

3632eeedb9 * VMCache: Added a UserData attribute which can be used by the lock holder.
* Added "bool consumerLocked" parameter to VMCache::Unlock() and
  ReleaseRefAndUnlock(). Since Unlock() may cause the cache to be merged with
  a consumer cache, the flag is needed to prevent a deadlock in case the
  caller still holds a lock to the consumer. Hasn't been a problem yet, since
  that situation never occurred.
* VMCacheChainLocker: Reversed unlocking order to bottom-up. The other
  direction could cause a deadlock in case caches would be merged, since the
  locking order would be reversed. The way VMCacheChainLocker was used this
  didn't happen, though.
* fault_get_page(): While copying a page from a lower cache to the top cache,
  we do now unlock all caches but the top one, so we don't unnecessarily
  kill concurrency.

f082f7f019 * Added vm_page::accessed flag. Works analogously to vm_page::modified.
* Reorganized the code for [un]mapping pages:
  - Added new VMTranslationMap::Unmap{Area,Page[s]}() which essentially do what
    vm_unmap_page[s]() did before, just in the architecture specific code, which
    allows for specific optimizations. UnmapArea() is for the special case that
    the complete area is unmapped. Particularly in case the address space is
    deleted, some work can be saved. Several TODOs could be slain.
  - Since they are only used within vm.cpp vm_map_page() and vm_unmap_page[s]()
    are now static and have lost their prefix (and the "preserveModified"
    parameter).
* Added VMTranslationMap::Protect{Page,Area}(). They are just inline wrappers
  for Protect().
* X86VMTranslationMap::Protect(): Make sure not to accidentally clear the
  accessed/dirty flags.
* X86VMTranslationMap::Unmap()/Protect(): Make page table skipping actually
  work. It was only skipping to the next page.
* Adjusted the PPC code to at least compile.

No measurable effect for the -j8 Haiku image build time, though the kernel time
drops minimally.

bcc2c157a1 Refactored vm_translation_map:
* Pulled the physical page mapping functions out of vm_translation_map into
  a new interface VMPhysicalPageMapper.
* Renamed vm_translation_map to VMTranslationMap and made it a proper C++
  class. The functions in the operations vector have become methods.
* Added class GenericVMPhysicalPageMapper implementing VMPhysicalPageMapper
  as far as possible (without actually writing new code).
* Adjusted the x86 and the PPC specifics accordingly (untested for the
  latter). For the other architectures the build is, I'm afraid, seriously
  broken.

The next steps will modify and extend the VMTranslationMap interface, so that
it will be possible to fix the bugs in vm_unmap_page[s]() and employ
architecture specific optimizations.

3fb2a94dfb * Inline {acquire,release}_spinlock(), when spinlock debugging is disabled.
* Use atomic_{and,or}() instead of atomic_set(), as there are no built-ins
  for the latter.

4f7b2c67b0 * gcc 4 features built-ins for atomic operations. If the macro
B_USE_BUILTIN_ATOMIC_FUNCTIONS is defined most atomic_*() functions are
  redefined as macros using the built-ins directly.
* Enabled that feature for the x86 build. Might work on other platforms as
  well, but that needs to be tested.

No significant speedup for the -j8 Haiku image build.

451ca8b4b4 PAGE_TYPE_GUARD was unused and for the other two types a simple one bit flag
suffices. Therefore replaced vm_page::type by vm_page::is_dummy.

d7455de2f6 allocate_page_run(): Use temporary lists to store the pages we're allocating.
This makes appending the pages to the active queue more efficient and we
don't need the vm_page::is_cleared bit anymore.

14429e896e Reverted the part of r31520 that made devfs_unpublish_partition() take a raw
device path + child partition name. When a "raw" device is unpublished the node
removal notification triggers the partition and child partitions to be
unpublished/removed. Since in that case the "raw" node is already unpublished
trying to resolve it in devfs_unpublish_partition() again to unpublish the child
partitions would fail, leaving the child partition nodes behind. When a new raw
device would then become available publishing its partitions would fail because
of these left behind nodes, causing bug #4587. Seeing that this code is more
compact and straight forward anyway I don't quite see why it was changed in the
first place.
