7d98230a73 uml: network and pcap cleanup
Some network device cleanup.

When setup_etheraddr found a globally valid MAC being assigned to an
interface, it went ahead and used it rather than assigning a random MAC like
the other cases do.  This isn't really an error like the others, but it seems
consistent to make it behave the same.

We were getting some duplicate kfree() in the error case in eth_configure
because platform_device_unregister frees buffers that the error cases
following tried to free again.

The pcap initialization routine wasn't doing the proper printk of its
information, causing a printk of the first part of that line to be
unterminated by a newline.

The pcap code had a bunch of style violations, which are now fixed.

pcap_setup wasn't returning false when it detected an unrecognized
option.

The printks in pcap_user all got UM_KERN_BLAH prepended to their
format strings.

pcap_remove now checks for a non-NULL pcap structure before it calls
pcap_close.

f34d9d2dcb uml: network interface hotplug error handling
This fixes a number of problems associated with network interface hotplug.

The userspace initialization function can fail in some cases, but the
failure was never passed back to eth_configure, which proceeded with the
configuration.  This results in a zombie device that is present, but can't
work.  This is fixed by allowing the initialization routines to return an
error, which is checked, and the configuration aborted on failure.

eth_configure failed to check for many failures.  Even when it did check,
it didn't undo whatever initializations has already happened, so a present,
but partially initialized and non-working device could result.  It now
checks everything that can fail, and bails out, undoing whatever had been
done.

The return value of eth_configure was always ignored, so it is now just
void.

56bd194bb2 uml: driver formatting fixes
Fix a bunch of formatting violations in the drivers:
	return(n) -> return n
	whitespace fixes
	emacs formatting comment removal
	breaking if(foo) return(n) into two lines

There are also a couple of errno use bugs:
	using errno in a printk when the failure put errno into a local variable
	saving errno after a printk, which can change it

c13e569073 [PATCH] uml: split memory allocation prototypes out of user.h
user.h is too generic a header name.  I've split out allocation routines from
it.

5e7672ec3f [PATCH] uml: const more data
Make lots of structures const in order to make it obvious that they need no
locking.

1da177e4c3 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!
