For some unknown reason, the data segment shrank by four bytes.  The text
segment stayed the same though:

	warthog>size vmlinux
	   text    data     bss     dec     hex filename
	2207804   66584  150189 2424577  24ff01 vmlinux

I would guess that in that kernel almost nothing uses LE unalignment.

The kernel works, so feel free to add my Acked-by to the patch.
