This is not necessary, since userland teams' page directories also
contain the kernel mappings, and avoids unnecessary TLB flushes. To make
that possible the vm_translation_map_arch_info objects are reference
counted now.
This optimization reduces the kernel time of the Haiku build on my
machine with SMP disabled a few percent, but interestingly the total
time decreases only marginally. Haven't tested with SMP yet, but for
full impact CPU affinity would be needed.

asynchronously.

and throws up a BAlert if not. Reuse this when the user clicks expand to check
for and grab the destination path. This fixes the problem that if the user
manually types in or pastes a destination path and then immediately clicks
Expand, the actual destination path used is never updated. Thanks to Daniel
Teixeira for reporting.

workspaces between this and the previous one.
* Note that this is mapped to a specific key on the keyboard (key 17), so
it will differ with the keymap, but will usually be the key below the escape
key.
* This closes ticket #2766.

* Changed the password window to use this feel.
* Later, the screen saver itself should use this feel whenever the password
mode is enabled. The password window should then use a modal-app feel, but
this doesn't work yet.

ticket #156; this might already fix this bug.

scheduler_set_thread_priority(). Setting the thread priority was the
only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
an operation vector now, which is initialized at kernel init time.
This allows for picking the most suitable scheduler for the machine
(e.g. a non-SMP scheduler on a non-SMP machine).

ctrl-alt-del pressed for 4 seconds, the system will reboot.
* Not sure if this makes any sense, though, as the button can be selected via
the keyboard as well (in BeOS, the reboot is triggered in the device, so it
will also work if the input_server hangs).

version should be preserved.

* Added a layout friendly constructor - it's not so nice to use, though, since
the original one already doesn't get a BRect (we just don't need the
resizing mode, and have to set the B_SUPPORTS_LAYOUT flag).
* Refactored size/frame computation a bit.
* Cleanup.

* Introduced macro KDEBUG_LEVEL which serves as a master setting.

index into the sLastCaller array is vint32, so after overflowing the
modulo operation would yield negative indices. This would cause the
256 bytes before the array to be overwritten. Might also be the cause of
#2866.

added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
added respective functions to the vm_translation_map operations. The
architecture specific implementation can now decide how to implement
them most efficiently. Added generic implementations that can be used,
though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
Instead it returns an implementation-specific handle that has to be
passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
and *_debug() variants, that work only for the current CPU,
respectively when in the kernel debugger. Also adjusted the
vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
tree.
* Also adjusted the m68k and ppc implementations with respect to the
vm_translation_map operation changes, but they are probably broken,
nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
suboptimal in any case. For systems with small memory it is too much
overhead, since one can just map the complete physical memory (that's
not done yet, though). For systems with large memory it counteracts
the VM strategy to reuse the least recently used pages. Since those
pages will most likely not be mapped by the page mapper anymore, it
will keep remapping chunks. This was also the reason why building
Haiku in Haiku was significantly faster with only 256 MB RAM (since
that much could be kept mapped all the time).
Now we're using a different strategy: We have small pools of virtual
page slots per CPU that are used for the physical page operations
(memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
Furthermore we have four slots per translation map, which are used to
map page tables.
These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.
