8c57aefdf8 Remove the B_PAGE_SIZE page size and replace it by a heap->page_size. This
allows for dynamic (heap)page sizes. It's currently just set to B_PAGE_SIZE
but I'm expermienting with the creation of differently sized heaps that could
use dynamic page sizes with that.

8531599a27 * KDiskDeviceManager::RescanDiskSystems() now also rescans all partitions with
the newly found disk systems.
* _ScanPartition() now allows to restrict the disk systems to a predefined set.
* _ScanPartition() now even scans partitions that already have a disk system
  assigned; if a better one is found, the existing one is replaced. It will
  ignore mounted or partitions with children, though.
* KPartition now also stores the priority of the disk system assigned to it.

e1b630c55d * Replaced the global cache pages hash table by an IteratableSplayTree
per cache.
* Changed the strategy vm_cache_acquire_page_cache_ref() uses to ensure
  that the cache isn't deleted while trying to get a reference. Instead
  of the global cache pages hash table lock, it holds the global cache
  list lock now. We acquire + release this lock in delete_cache() after
  removing all pages and just before deleting the object.
* Some small optimizations using the property that the cache's pages are
  ordered, now (vm_cache_resize(), vm_page_write_modified_page_range(),
  vm_page_schedule_write_page_range()).
* Replaced some code counting a cache's pages by simply using
  vm_cache::page_count.

a5db16fc79 * Implement counting free pages in kernel heaps.
* Suggest growing when there are less than 10% free pages in the last heap.
  Previously it would suggest growing when there were less than three free
  pages, which wasn't really any good measure. In quite a few cases this could
  have lead to too late growing and running out of heap space.
* Only panic when memory allocation fails while growing kernel heaps. Otherwise
  just output a message and return NULL. Even this panic is not really
  necessary and should be continueable, but for now I'd like to see if this
  situation actually happens.

  and returns an error, if that fails.
* Adjusted code using the classes accordingly. Replaced a few
  InitCheck() methods in the network code by Init().

285b754fa7 * dec_vnode_ref_count() can now also directly free the vnode if requested
(and if it isn't used anymore).
* vnode_low_memory_handler() now just calls it this way, so it doesn't have
  to use two passes anymore, and can always write back vnodes without having
  the busy flag set.

2965c99fea * Changed the _kern_exec() and _kern_load_image() syscalls. They expect
a flattened argument/environment buffer now. This simplifies the work
  for the kernel a bit, since it can just copy the buffer and check
  whether it looks OK instead of messing around with individual strings.
  The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
  When more arguments are passed, we fail with a proper error code
  (instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
  name, which is not correct.

df7096a4aa * Added malloc_nogrow() function that does allocation without triggering or
waiting for a heap grow.
* Use that nogrow version in the VM code to avoid a deadlock with the address
  space lock when a grow operation would try to create an area while a malloc
  happened from such a function in the VM.
* When waiting for a grow to happen, notify the waiting thread from the grower
  also if it failed to allocate a new heap. Otherwise a thread would just sit
  there and wait until another thread requested growing too and that one
  succeeded (or just forever in the worst case).
* Make the dedicated grow heap growable too. If the current grow heaps run low
  on memory it will instruct the grower to allocate a new grow heap. This
  reduces the likelyhood of running out of memory with no way to grow to a
  minimum. As the growing is done asynchronously it is still possible to
  happen, but it is highly unlikely as the grow heap is solely used to
  allocate memory in the process of creating new heap areas and it will even
  try using normal public memory if the dedicated memory has run out.
* Reduced the dedicated grow heap from 2 to 1MB. As it can now grow itself, it
  doesn't need to last so long.
* Extract heap creation into it's own function that does area creation and heap
  attach and use this function for growing normal and grow heaps.

065ef7eb5f Replace the legacy driver mutex with a recursive lock. This fixes the deadlock
when hot-plugging a USB mass storage device. The legacy driver (usb_disk in
this case) was rescanned which locked the legacy driver mutex. The insertion
of the new device node caused the disk device manager (notified through node
monitoring) to try to scan the new node. As opening the node triggers
LegacyDevice::InitDevice() that locks the legacy driver mutex again a deadlock
occured.

9223644a02 Add a welcome message including the revision number when initializing the
syslog so syslogs always contain the revision number too (as does serial
output).
This is only necessary because the early part of the serial output (that
contains the revision number) does not make it into the syslog. So fixing that
might be the better way.

01e46bdb18 * Extract the KDL keymap to a separate header and provide a 'sg' swiss german
keymap there too.
* Add a config header where one can select what KDL keymap should be used
  (currently only 'us' and 'sg' are available though).
* Provide a third keymap that is used when the alt modifier is used (the swiss
  german keymap is pretty useless without alt as all the useful keys like
  backslash and curly braces use alt).

Our KDL is so powerful and nice to use, the only thing that bothered me was
that I always had to think about where some of the special keys are located in
the US keymap. So this simple compile-time keymap switching provided to be
helpful for me and might be for others too. Keymaps for other layouts obviously
have to be written before this becomes really useful.

added to their parent. Currently, only the existence of B_FIND_MULTIPLE_CHILDREN

73aa393d73 * Introduced pipes in the kernel debugger. The syntax is similar to
pipes in the shell, though the semantics is a little different: The
  second command is invoked whenever the first command has written a
  complete line. The line is passed as last argument to the second
  command. The new command flag B_KDEBUG_PIPE_FINAL_RERUN causes the
  second command to be invoked again (with NULL argument) after the
  first command is done.
* Added kprintf_unfiltered() and kputs_unfiltered() which bypass the
  pipe mechanism and directly print to the bluescreen/serial output.
* Moved most commands from debug.cpp to the new
  debug_builtin_commands.cpp.
* B_KDEBUG_DONT_PARSE_ARGUMENTS commands don't get an argument anymore,
  if it would consist of white space only.
* Added new debugger command return value B_KDEBUG_ERROR, which
  indicates that executing the command failed. This return code will
  abort a complete pipe.
* Since debugger commands can nest (i.e. one command can invoke another
  one) the setjmp()/longjmp() mechanism to restore the stack after a
  page fault in a command needs more than one jump buffer.
* Added abort_debugger_command(), which longjmp()s out of the currently
  executed command. This will also abort the current pipe.
* When pagination is enabled pressing "a" will abort the running command
  (as opposed to "q" which only disables the blue screen output, but
  lets the command continue).
* Added debugger commands:
  - "grep" which can be used to filter output by pattern. Removed the
    "filter" command and the underlying mechanism that did that before.
  - "head" which prints only the first lines of output of another
    command.
  - "wc" counts lines, words, and characters of another command's
    output.

9a18e1d269 * Do not delete the device handed over to the devfs when deleting the vnode
as it seems devfs should not take over ownership. The device is deleted
  in republish_driver for legacy drivers before the call to devfs_unpublish_device
  that in turn deletes the vnode. This looks generally suspicious to me as
  the device pointer the devfs vnode may still use gets invalid for a certain
  amount of time (until the node is unpublished). So maybe the devfs should
  take ownership of the device afterall and it shouldn't be deleted by the
  device_manager/legacy driver functions. Axel please review.
* Do not try to delete the IOScheduler for now as creating one is disabled
  currently too.

This fixes the crash on rescans of legacy drivers as seen when unplugging
USB devices.

e4d2f9ba4f Removed the condition that only caches with a source can be merged.
Instead we only allow temporary caches to be merged. This remedies the
problem that after fork() + join() there remains a superfluous cache
layer for all RAM areas.
I haven't tested it, but this might improve the jam situation
memory-wise (huge heap is committed one less time), though it might
worsen it performance-wise (lots of heap pages are moved with every
merge).

368167ede8 * Integration of the new driver architecture.
* Moved devfs from fs/ to device_manager/, and separated the legacy driver
  support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
  - legacy SATA and ISA IDE support is disabled, the drivers haven't been
    ported yet.
  - The not yet used ATA bus manager hasn't been ported yet, either.
  - AHCI changes have not been tested.
  - the listdev command has been removed from the build (as it currently
    doesn't work anymore).
  - device manager generated IDs currently are not freed anymore when a device
    node is removed.
  - generic drivers can't yet use the new driver architecture.
  - simple busses that do not support device types won't work yet.
  - legacy driver publishing/unpublishing (ie. what USB needs) has not been
    tested, and may be broken.

  a user thread context because the lower 1MB of the address space is used.

a8af2b6dda Some work on pthreads:
* Made the pthread_cond_t internals public. This is necessary to support
  process shared condition variables. Fixed initializer macro.
* Made the pthread_rwlockattr_t structure opaque.
* pthread_t is no longer typedef'ed to int. It's the pointer to the
  internal _pthread_thread structure.
* Removed __get_pthread(). pthread_self() can be used instead.
* No longer tunnel the pthread exit value through Haiku's thread exit
  value. We do have a separate field in the _pthread_thread structure
  for it, now.
* Handle detaching of threads correctly.
* pthread_rwlockattr_{g,s}etpshared() use the
  PTHREAD_PROCESS_{SHARED,PRIVATE} constants, now.
* Commented out yet unsupported structures (barriers, spinlocks).
* Rebuilt APR optional package. The pthread changes weren't binary
  compatible.

Changed condition variables so that it is allowed to block (e.g. lock

lifetime.

6b202f4e3d * Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
  several kernel headers into a shared part and one that is still kernel
  private. Adjusted all affected Jamfiles and source in the standard x86
  build accordingly. The build for other architectures and for test code
  may be broken.
* Quite a bit of userland code still includes private kernel headers.
  Mostly those are <util/*> headers. The ones that aren't strictly
  kernel-only should be moved to some other place (maybe
  headers/private/shared/util).
