[IRDA]: irlmp_unregister_link() needs to free lsaps.
While testing the mcs7780 based IrDA USB dongle I've stumbled upon
memory leak in irlmp_unregister_link(). Hashbin for lsaps is created in
irlmp_register_link and should probably be freed in irlmp_unregister_link().

Convert files to UTF-8 and some cleanups
* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

[IrDA]: Fix IrDA build failure
When having built-in IrDA, we hit the following error:

net/built-in.o: defined in discarded section `.exit.text' of
net/built-in.o

make[1]: *** [.tmp_vmlinux1] Error 1
make: *** [_all] Error 2

This is due to the irda_init fix recently added, where we call __exit
routines from an __init one. It is a build failure that I didn't catch
because it doesn't show up when building IrDA as a module. My apologies
for that.
The following patch fixes that failure and is against your net-2.6
tree. I hope it can make it to the merge window, and stable@kernel.org
is CCed on this mail.

[PATCH] mark struct file_operations const 8
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

The comment at the nesting lock says:

	/* Careful for priority inversions here !
	 * irlmp->links is never taken while another IrDA
	 * spinlock is held, so we are safe. Jean II */

So, under the assumption the author was right, it just needs a lockdep
annotation.

[IrDA]: Use alloc_skb() in IrDA TX path
As pointed out by Christoph Hellwig, dev_alloc_skb() is not intended to be

dev_alloc_skb() on the TX path, and this patch fixes that.

Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
