This version is split from my earlier patch, including just the
portions that ar required for Linus' tree.

Fixes the following compile errors:

Jeff Dike b53f35a809 uml: network driver MTU cleanups
A bunch of MTU-related cleanups in the network code.

First, there is the addition of the notion of a maximally-sized packet, which
is the MTU plus headers.  This is used to size the skb that will receive a
packet.  This allows ether_adjust_skb to go away, as it was used to resize the
skb after it was allocated.

Since the skb passed into the low-level read routine is no longer resized, and
possibly reallocated, there, they (and the write routines) don't need to get
an sk_buff **.  They just need the sk_buff * now.  The callers of
ether_adjust_skb still need to do the skb_put, so that's now inlined.

The MAX_PACKET definitions in most of the drivers are gone.

The set_mtu methods were all the same and did nothing, so they can be
removed.

The ethertap driver had a typo which doubled the size of the packet rather
than adding two bytes to it.  It also wasn't defining its setup_size, causing
a zero-byte kmalloc and crash when the invalid pointer returned from kmalloc
was dereferenced.

Jeff Dike cd1ae0e49b uml: network formatting
Style and other non-functional changes in the UML networking code, including
	include tidying
	style violations
	copyright updates
	printks getting severities
	userspace code calling libc directly rather than using the os_*
wrappers

There's also a exit path cleanup in the pcap driver.

Arnaldo Carvalho de Melo 98e399f82a [SK_BUFF]: Introduce skb_mac_header()
For the places where we need a pointer to the mac header, it is still legal to
touch skb->mac.raw directly if just adding to, subtracting from or setting it
to another layer header.

This one also converts some more cases to skb_reset_mac_header() that my
regex missed as it had no spaces before nor after '=', ugh.

Jeff Dike 8210fd2a9f [PATCH] uml: use get_random_bytes() after random pool is seeded
When the UML network driver generates random MACs for its devices, it was
possible for a number of UMLs to get the same MACs because the ethernet
initialization was done before the random pool was properly seeded.

This patch moves the initialization later so that it gets better randomness.

Paolo 'Blaisorblade' Giarrusso 854e981cc6 [PATCH] uml: fix hugest stack users
The C99 initialization, with GCC's bad handling, for 6K wide structs (which
_aren't_ on the stack), is causing GCC to use 12K for these silly procs with 3
vars.  Workaround this.

Note that .name = { '\0' } translates to memset(->name, 0, '->name' size) - I verified
this with GCC's docs and a testprogram.

Linus Torvalds 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!
