3cf7ecd1e4 * Added <sys/mman.h> header. It declares only mmap() and munmap() yet
and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
  path to an FD parameter. Changed vm_map_file() accordingly and
  adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
  and map_backing_store(). If true and the address specification is
  B_EXACT_ADDRESS, all areas in the specified address range will be
  deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
  created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
  fork()ing those areas won't be copied CoW, but rather be cloned. This
  is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
  anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
  that we can't partially unmap areas. Otherwise the functions should be
  rather compliant. We also support the non-POSIX extension
  MAP_ANONYMOUS.

41f8d41647 Applied patch by Rene Gollent:
* Add a cached_pages field to the system_info structure, and change the
  meaning of the used_pages field to not include cached pages.
* Provide the needed info using the new calls vm_get_available_memory(),
  and vm_page_num_available_pages().

d1189f0b05 Naive implementation of transfer_area(). It follows the suggested sematics
of the resolved ToDo, but could probably be made more efficient. Instead of
transfering the area, the area is cloned into the target teams' address space
and the original is deleted. This generates a new area_id for the transfered
area (as suggested by the ToDo). Updated syscall prototypes according to the
status_t to area_id return type change.

477c9d1dc0 * vm_set_area_protection() would remap the whole area instead of just the page
it intended to. That resulted in more writable pages where you wouldn't want
  them (ie. allowing the area to change pages in lower caches).
* We were losing modified pages: vm_unmap_pages() sometimes has to preserve
  the modified flag (eg. when called from page fault).
* Both of these were responsible that stealing active pages would crash
  applications - even if less likely, this could also have happened when
  stealing inactive pages. Therefore, I've activated stealing active pages
  again.
* The page writer now pushes the pages of busy vnodes to the end of the queue,
  so that it won't pick them up again too soon (the vnode destruction would
  be in the process of writing those pages back, anyway).
* The page thief now triggers the page writer to run once it has to steal
  active pages. This might be a bit too aggressive, though.

9d8c209014 * vm_remove_all_page_mappings() now returns an accumulation of the flags of
the unmapped page.
* This is needed by everyone who calls this to make sure modifications to a
  page aren't ignored. Namely, the page scanner and the page thief were
  affected.
* Cleaned up locking the page's cache a bit in page_thief(); there is now
  a helper class that takes care of everything.

a6778735f9 bonefish+axeld:
* We now have a page writer that takes some pages from the modified queue
  and writes it back every few seconds. It can be triggered by the page
  scanner to do that more often, though. That mechanism can be greatly
  improved once we have our I/O scheduler working.
* Removed vm_page_write_modified_page() again - it was all "eaten up" by
  the page writer.
* Reworked vm_page_write_modified_pages() a bit: it now uses
  vm_test_map_modification() and vm_clear_map_flags() instead of the
  iterating over all areas which wouldn't even work correctly.
  The code is much simpler now, too.
* You usually put something to the tail of a queue, and remove the contents
  from the head, not vice versa - changed queue implementation to reflect this.
* Additionally, there is now a enqueue_page_to_head() if you actually want the
  opposite.
* vm_page_requeue() allows you to move a page in a queue to the head or tail.
* Replaced vm_clear_map_activation() with vm_clear_map_flags() which allows
  you to clear other flags than PAGE_ACCESSED.
* The page scanner dumps now some arguments with each run.
* Removed the old disabled pageout_daemon() from NewOS.

e6dc7903e4 * vm.h no longer includes vm_types.h - only those that actually need access
to the private VM types are including vm_types.h now.
* Removed vm_page, vm_area, vm_cache, and vm_address_space typedefs; it's
  cleaner this way, and the actual types are only used in C++ files now,
  anyway.
* And that caused changes in many files...
* Made commpage.h self-containing.
* Minor cleanup.

6d4aea4796 bonefish+axeld:
* Removed the vm_cache/vm_store ref_count duality that besides being a bit ugly
  also created the page dameon cache retrieval problem: now, only areas (and
  cache consumers) retrieve a reference to the store (and therefore, the vnode).
  The page daemon doesn't need to care about this at all anymore, and the pseudo
  references of the vm_cache could be removed again.
* Rearranged deletion of vnodes such that its ID can be reused directly after
  fs_remove_vnode() has been called.
* vm_page_allocate_page() no longer panics when it runs out of pages, but just
  waits for new pages to become available using the new sFreeCondition condition
  variable - to make sure this happens in an acceptable time frame, it'll
  trigger a run of the low memory handlers.
* Implemented a page_thief() that steals inactive pages from caches and puts
  them into the free queue. It runs as a low memory handler.
* The file cache now sets the usage count on the pages it inserts into the
  cache (needs some rework though, cache_io() doesn't do it yet).
* Instead of panicking, the kernel will currently dead lock in low memory
  situations, since BFS does a bit too much in bfs_release_vnode().
* Some minor cleanup.

87689e25ea * sMappingLock is now a mutex instead of a spinlock.
* The vm_translation_map is now correctly held in all of the vm_ mapping
  functions.
* Removed the old vm_daemons.c file - there is now a new vm_daemons.cpp
  which contains the beginnings of our new page daemon.
  So far, it's pretty static and not much tested. What it currently does
  is to rescan all pages in the system with a two-handed clock algorithm
  and push pages into the modified and inactive lists.
* These inactive pages aren't really stolen yet, even though their mappings
  are removed (ie. their next access will cause a page fault). This should
  slow down Haiku a bit more, great, huh? :-)
* The page daemon currently only runs on low memory situations, though.

  in preparation of the page scanner rewrite.

1594e83f84 * All mapped pages that are not wired (ie. locked) now have a vm_page_mapping object
that points to both, the page and the area the page is in. This will allow a page
  scanner to steal unused pages when necessary.
* The locking is currently done with a spinlock which we might want to have another
  look at one day.
* dump_page() and dump_area_struct() now dump the page mappings as well.

ca954b7816 Another work-in-progress towards having extra structures per mapping per page:
* vm_area and vm_page now have a new field "mappings" where they will store lists
  of vm_page_mapping structures. vm_page::ref_count is gone, as it's no longer
  needed (it was never updated correctly, anyway).
* vm_caches now have a type field, ie. CACHE_TYPE_RAM for anonymous areas - this
  makes the stores a bit less independent, but is quite handy in several places.
* Added new vm_map_page() and vm_unmap_pages() functions to be used whenever you
  map in or unmap pages into/from an area. They don't do much more than handling
  vm_page::wired_count correctly right now, though (ie. B_LAZY_LOCK is now working
  as expected as well).
* Moved the device fault handler to vm_map_physical_memory(); it was not really
  used as a fault handler, anyway.
* Didn't notice Ingo's changes to the I/O space region broke lock_memory(). It
  now checks the type of the area that contains the memory, and doesn't lock
  anymore if not needed which solves the problem in a platform independent way.
* Implemented lock_memory() and unlock_memory() for real: they now change the
  vm_page::wired_count member to identify pages that shouldn't be paged out.
* vm_area_for() now uses vm_area_lookup() internally.
* Fixed various potential overflow conditions with areas that reach 0xffffffff.
* Creating anonymous areas with B_FULL_LOCK no longer causes vm_soft_fault()
  to be called, instead, the pages are allocated and mapped (via vm_map_page())
  directly.
* Removed the _vm_ prefix for create_area_struct() and create_reserved_area_struct().
* Fixed a bug in vm_page_write_modified() that would not have enqueued pages that
  failed to be written to the modified queue again when needed.

3eca858515 * Moved the early startup VM allocation functions from vm_page.c to vm.cpp.
* Renamed them, made everything static besides vm_allocate_early() (previous
  vm_alloc_from_kernel_args()) which now allows you to specify a different
  virtual than physical size, and therefore makes vm_alloc_virtual_from_kernel_args()
  superfluous (which isn't exported anymore, and is now called allocate_early_virtual()).
* Enabled printing a stack trace on serial output on team crash - it doesn't hurt
  for now, anyway.
* Cleanup.

79f73dbc56 * vm_page::offset is now called cache_offset and is now an uint32 instead of off_t;
this saves 4 bytes per page. To compensate the loss of bytes, the offset is now
  stored in page size units, that's enough to address 2^44 or 16 TB (which is now
  the maximal supported file size!).
* Renamed vm_page::ppn to physical_page_number.

them apart (this even saves a pointer from vm_virtual_map to its address space)

* vm_create_address_space() did not check if creating the semaphore succeeded
* Removed team::kaspace - was not really needed (introduced a new vm_kernel_address_space()
  function that doesn't grab a reference to the address space)
* Removed vm_address_space::name - it was just a copy of the team name, anyway,
  and there is always only one address space per team
* Removed aspace_id - the address space is now using the team_id
* Some cleanup.

51a3c450be The short story: we now have MTRR support on Intel and AMD CPUs (the latter
has not yet been tested, though - I'll do this after this commit):
* Removed the arch_memory_type stuff from vm_area; since there are only 8 memory
  ranges on x86, it's simply overkill. The MTRR code now remembers the area ID
  and finds the MTRR that way (it could also iterate over the existing MTRRs).
* Introduced some post_modules() init functions.
* If the other x86 CPUs out there don't differ a lot, MTRR functionality might
  be put back into the kernel.
* x86_write_msr() was broken, it wrote the 64 bit number with the 32 bit words
  switched - it took me some time (and lots of #GPs) to figure that one out.
* Removed the macro read_ebp() and introduced a function x86_read_ebp()
  (it's not really a time critical call).
* Followed the Intel docs on how to change MTRRs (symmetrically on all CPUs
  with caches turned off).
* Asking for memory types will automatically change the requested length to
  a power of two - note that BeOS seems to behave in the same, although that's
  not really very clean.
* fixed MTRRs are ignored for now - we should make sure at least, though,
  that they are identical on all CPUs (or turn them off, even though I'd
  prefer the BIOS stuff to be uncacheable, which we don't enforce yet, though).

4393552b4d The heap is now located at 384 MB, and creates a reserved range that spans over the
following 1152 MB - that area only guarantees that the heap can grow this much before
the application need the memory for something else. And even then, the heap range
is reused from top-to-bottom, allowing for maximum heap usage. Of course, if the
memory after the heap range is not claimed yet, it can still be claimed by the heap,
too. Added new syscall to create the reserved range.
Fixed a bug in vm_delete_areas(): when it removed reserved areas, the area list
could get messed up.
Fixed a bug in resize_area(): resized areas could never be deleted (missing vm_put_area())!
resize_area() now supports reserved regions (but not perfectly yet, see ToDo items).

024bab9721 Added vm_delete_aspace() again (although it works a bit differently then before).

a2ff38d818 vm_page no longer keeps a pointer to the vm_cache_ref but to the vm_cache.
This cleans the page handling when having to make an area copy-on-write;
regions belong to vm_cache_ref, pages to vm_cache.
Added prototype for new call vm_copy_area().
Fixed some return types.

1a705b91b7 Removed team::_aspace_id since it already has a direct pointer to it.
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.

36ce5c0164 Changed the way the vnode cache is set - it's now cleaner and can no longer
allocate a cache twice.

383cdedbd2 Several follow-up changes required by the changes either to the VFS
syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).

f236d16605 Removed the vm_get_region_info() call and the vm_region_info structure -
they are now replaced by get_area_info() and the area_info structure.
get_area_info() still misses some pieces, though.
Added all missing VM user/kernel syscalls.
