901f1930e1 * Moved memset_physical() to vm.cpp and made it available in the kernel.
* Added memcpy_to_physical().

808de9c700 * The undertaker was not locking when enqueuing the thread structure in
the free queue.
* "thread" also prints the thread's I/O priority.

703aecaaa5 * Instead of having the mount_link, struct vnode now subclasses from
DoublyLinkedListLinkImpl, and fs_mount now uses a DoublyLinkedList instead
  of a typeless struct list.
* Also added a constructor/destructor to fs_mount which simplifies and cleans
  some code.
* This should not contain any functional changes :-)

552c8edcd1 * fs_sync() now holds the sVnodeMutex while iterating over the mount list.
* This has the advantage that we no longer need to call get_vnode(), and
  instead can use lookup_vnode().
* This means at least most of the "corrupted BFS inode" messages should be
  gone; they were produced when fs_sync() tried to get already deleted vnodes.
  This was actually harmless, but doesn't really help in trusting your system :-)
* Also, it no longer tries to write back removed vnodes.
* And finally, it now uses a marker vnode when iterating over the list, so
  that it doesn't need to break out of the loop anymore, and can always sync
  all willing vnodes.

d52718a5f8 Fixed serious race condition: If the thread waiting for a request was
interrupted, another thread closing the other end of the pipe could
invoke thread_unblock() while the first thread already entered
mutex_lock(). This would make the first thread think it successfully
locked the mutex, without removing its (on-stack) wait entry from the
mutex queue, thus leading to crashes.

1e2bc11e99 bonefish+mmu_man: fix cbuf_user_memcpy_from_chain() returning an error when the source buffer was NULL despite being asked for 0 bytes, while the counterpart was actually not creating a buffer for 0 bytes to send... Also don't bother calling it from receive_data() in that case anyway.
This fixes a deadlock in SoundPlay that made it freeze when trying to play the 2nd sound.

ecb3d008d6 If a device reports no media is present, don't try to get the geometry anyway.
This confused some USB card readers, that would stop working if you still
requested the geometry when they reported no media.
Note the case that the B_GET_MEDIA_STATUS fails (because it's not implemented or
an error occured) is still handeld in _GetMediaStatus() and then we still try to
get the geometry to check for media presence.
This should fix that some USB card readers wouldn't work and should also remove
the wrongly reported size in DriveSetup for CD drives that don't actually contain
a media.

1fdc8a49aa * Factored out the demangled function call dump to a print_demangled_call().
* The stack_trace() command now also uses this call by default to give you
  the arguments to all functions in a stack crawl (beware of templates for now,
  though).
* Use the new option '-d' to disable the demangling. You can now also specify
  '-d' in the "call" command which has the same meaning there.
* NULL pointers are now printed as "NULL", and NULL strings are printed as
  well.

ddecb4a7da * Changed the way the demangle functionality works: instead of having a kernel
debugger add-on set a demangle hook, all modules under debugger/demangle/ are
  now considered demangle modules.
* Added another function to the demangle module interface that gives you access
  to the arguments.
* Implemented a demangling module for GCC2.
* The older demangling module is now called "gcc3+", but doesn't support
  getting the arguments yet.
* The "call" KDL command is now using demangling to automatically show you
  the arguments of a call from a stack crawl.
* Minor cleanup.

4a4abaf25f mmlr:
* Actually call prepare_sleep_state() instead of calling enter_sleep_state()
  twice...
* Commented out disabling interrupts when calling enter_sleep_state(), as our
  ACPI modules would then crash (needs memory & uses sems with interrupts
  disabled). This way, it at least works on some hardware, including emulators
  (as before).

74785e79db * Added "from" address space parameter to vm_swap_address_space()/
arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
  vm_translation_map_arch_info indicating on which CPUs the address
  space is active. This allows flush_tmap() to avoid ICI for user
  address spaces when the team isn't currently running on any other CPU.
  In this context ICI is relatively expensive, particularly since we map
  most pages via vm_map_page() and therefore invoke flush_tmap() pretty
  much for every single page.
  This optimization speeds up a "hello world" compilation about 20% on
  my machine (KDEBUG turned off, freshly booted), but interestingly it
  has virtually no effect on the "-j2" haiku build time.
