I've pretty much narrowed down where the unaligned load is. It coming from
init_page_buffers. I had to disable inlining of this function to simplify
the code.

The problem seems to occur in accessing the page buffers for the page.
The above code has a BUG_ON checking the alignment of the page. I then
added a BUG_ON to check the alignment of bh:
static __attribute__((__noinline__)) void
init_page_buffers(struct page *page, struct block_device *bdev,
sector_t block, int size)
{
struct buffer_head *head = page_buffers(page);
struct buffer_head *bh = head;
int uptodate = PageUptodate(page);
BUG_ON ((long)bh & 7);
However, with this BUG_ON the unaligned access doesn't occur...
The assembly code changes to:
00000000401f9698 <init_page_buffers>:
401f9698: 08 03 02 41 copy r3,r1
401f969c: 08 1e 02 43 copy sp,r3

There must be some kind of race in setting bh? This is a UP build.
Any ideas.
I'm sure this came up before. A different .config was used and the
problem disappeared.
However, the system didn't fully boot. There was another unaligned
load in a ipv6 module. I caught this because I still have the following
BUG_ON in unaligned.c:

Do we need to emulate ldd in the kernel?
