it readable/writable for all userland apps. This is not what we want here.
We want to make the area cloneable for the registrar and hence use the
new flag B_USER_CLONEABLE_AREA. But there seems to be a bug that causes
strange things to happen, when using that flag only, therefore we go with
all of them until it is fixed.

* The counter semaphore is now only released when writing a command into
an formerly empty area. The userland part is aware of that. :-)

without any drivers in /dev/audio.

to userland applications. A userland server (probably the registrar) will
register as the server responsible for delivering the messages. The
messages are passed to it via shared memory.
The advantage over sending the messages directly will be, that they won't
need to be dropped, if the receiver port is temporarily full.
Currently only the kernel side is implemented. Completely untested yet.

append-only and hence has very compact storage and a comparatively small
footprint implementation. Can be used for kernel->userland messaging.

cache_io() should now finally work correctly in all cases.

this file still does the right thing as suggested by Michael Pfeiffer.

Added short description to find_reserved_area() as that name is not that good.
vm_reserve_address_range() now doesn't do anything if the requested size
of the reservation is zero.

and not on a page boundary had been executed with a I/O size too large,
and thus clobbering all sorts of memory (oh my god).
The problems with ResourceFile now seems to be gone.

up for the first time, it will try to load all drivers that may export
devices there. Those devices will currently stay loaded, though - this
will only be changed when load_kernel_add_on() is able to cache add-ons.
Renamed pnp_devfs_probe() to pnp_devfs_register_device().
Fixed debug output for devfs_create().

con_init() now takes care of the initialization of its currently built-in
console drivers itself.

Also includes the loader of R5 styled drivers (taken from dev.c).

Comment cleanup for consistency.
Renamed remaining "omode" variables to openMode.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10831 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added kernel private calls load_module() and unload_module() that can be used to
load/unload modules by path.
load_module_image() now only mentions when it couldn't load a module when tracing
is enabled (because the device manager uses it to determine if an add-on is a
module or an old-style driver).

not how it is declared in R5, but it is what actually is returned.
* Fixed _user_read_port_etc(): It didn't copy the message code back to
userland, if the message had a size > 0.

now used from there, sorry Ingo (I forgot to commit the Jamfile that
included fs_info.c).
Minor comment cleanup to make their appearance consistent throughout
the kernel.

this situation. Reported by Ingo.

check for B_TIMED_OUT and B_WOULD_BLOCK, but it got through with other
errors.
Removed special error check for "known" error codes from port_buffer_size_etc(),
read_port_etc() and write_port_etc() - they no longer print out a warning in
that case.

later).
