the linux module, since it is not cross-platform
- move linprocfs from "files" and "options" to architecture specific files,
since it only makes sense to build this for those architectures, where we
also have a linuxolator
- disable the build of the linuxolator on our tier-2 architecture "Alpha":
* we don't have a linux_base port which supports Alpha and at the
same time is not outdated/obsoleted upstream/in a good condition/
currently working
* the upcomming new default linux base port is based upon Fedora
Core 3 (security support via http://www.fedoralegacy.org), which
isn't available for Alpha (like the current default linux base
port which is based upon Red Hat 8)
* nobody answered my request for testing it ~1 month ago on
current@ and alpha@ (it doesn't surprises me, see above)
* a SoC student wouldn't have to waste time on something which
nobody is willing to test
This does not remove the alpha specific MD files of the linuxolator yet.

If the embedded controller exists before the sysresource devices, for
example, it will be attached first. Instead, let the normal device
order function work as we first desired. [1]
There still remained a problem where we couldn't allocate resources in
acpi0 that were passed up by the sysresource pseudo-devices. These
devices had to probe/attach first to give their resources to acpi, then
acpi would allocate them before probing/attaching other devices. To
work around this, we attach them from acpi_sysres_alloc(). A better
approach would be to implement multi-pass probe/attach in newbus but
that's a much bigger task.

assuming them to be inflight write buffers. This is not always the case.
bufdaemon might hold the buffer lock and give up writing the buffer due to it
having dependencies, the file system being suspended or the vnode lock being
held by another thread. When bufdaemon decides to write the buffer there is
still a window before bufobj_wref() has been called, allowing other threads to
believe that the vnode has no dirty buffers or inflight writes.
Try harder to flush first block of new subdirectory to get rid of MKDIR_BODY
dependency.

for signicantly optimized UDP socket I/O when using a single UDP
socket from many threads or processes that share it, by avoiding
significant locking and other overhead in the general sosend()
path that isn't necessary for simple datagram sockets. Specifically,
this change results in a significant performance improvement for
threaded name service in BIND9 under load.

Add back in a scheme to emulate old type major/minor numbers via hooks into
stat, linprocfs to return major/minors that Linux app's expect. Currently
only /dev/null is always registered. Drivers can register via the Linux
type shim similar to the ioctl shim but by using
linux_device_register_handler/linux_device_unregister_handler functions.
The structure is:
struct linux_device_handler {
char *bsd_driver_name;
char *linux_driver_name;
char *bsd_device_name;
char *linux_device_name;
int linux_major;
int linux_minor;
int linux_char_device;
};
Linprocfs uses this to display the major number of the driver. The
soon to be available linsysfs will use it to fill in the driver name.
Linux_stat uses it to translate the major/minor into Linux type values.
Note major numbers are dynamically assigned via passing in a -1 for
the major number so we don't need to keep track of them.
This is somewhat needed due to us switching to our devfs. MegaCli
will not run until I add in the linsysfs and mfi Linux compat changes.

a route looking like this:
(0) 192.0.2.200 UH tun0 =>
When removing this route the kernel will start to walk
the address space which looks like a hang on 64bit platforms
because it'll take ages while on 32bit you should see a panic
when kernel debugging options are turned on.
The problem is in rtrequest1:
if (netmask) {
rt_maskedcopy(dst, ndst, netmask);
} else
bcopy(dst, ndst, dst->sa_len);
In both cases the len might be 0 if the application forgot to
set it. If so ndst will be all-zero leading to above
mentioned strange routes.
This is an application error but we must not fail/hang/panic
because of this.
