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.

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.

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.

* The VESA driver now supports gettings the EDID information as well; this
is necessary now, since the app_server no longer takes over the mode the
boot loader had chosen.

the kernel part again.

added to their parent. Currently, only the existence of B_FIND_MULTIPLE_CHILDREN
influences the priority.
* This makes it possible to register/probe intelligent busses earlier than
simple/generic busses.
* Reenabled the ISA bus manager using the new device architecture; the
ide_isa driver can and will now actually work.
* device_node::Probe() now sets the global sGenericContextPath for generic
nodes. This causes a special handling in _GetNextDriverPath().

* Therefore, device_manager::rescan_node() now actually causes the
driver::rescan_child_devices() function to be called, instead of probing
again.
* Added a device_node::Reprobe() method that does what Rescan() did previously.
* Probe() should now also work with "dumb" busses that don't support type
information - it will now probe all of these nodes.

B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
structure (thus breaking BeOS binary compatibility), containing a
counter which is incremented whenever a thread has to wait for the
spinlock.
* Added macros for spinlock initialization and access and changed
code using spinlocks accordingly. This breaks compilation for BeOS --
the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
the team spinlocks.

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.

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.

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).

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.

several kernel headers into a shared part and one that is still kernel

* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly

- Removed the pthread_mutex_t indirection (the type was a pointer to
the actual structure which was allocated on the heap), as it made
sharing the mutex between processes impossible.
- Removed the distinction between process shared and non-shared
mutexes. Benaphores work just as well in shared memory, so we always
use them.
