remove sk_protinfo series

Hi David,

This series addresses Christoph and Jean concerns about the overhead
caused by private slab caches in every family, by making sk_alloc use kmalloc if no slab cache is used, and as a transitional mechanism the zero_it semantic is maintained, that is, if slab is NULL and zero_it is 1, use the generic "slab" (sk_cachep) cache.

Now only the ham radio protocols (AX25, NETROM and ROSE) and
net/wanrouter uses sk_protinfo to store an private area directly, and bluetooth uses it as a second level for proto info while using a private slab cache for the first level of proto info.

This series has atm and pppox in addition to the set of families
covered in the first series.

I think we'll need to defer this to 2.6.12

When I setup my 2.6.12 net pending queue tomorrow I'll pull from your tree. I'll probably set this up tomorrow and it will be at:

	bk://kernel.bkbits.net/davem/net-2.6.12

I'll announce it.

Pulled into my 2.6.12-pending tree, thanks Arnaldo.
