Hi Nicholas:
I met some problem for this patch, like this:
kva = vmalloc(3*1024k);
remap_vmalloc_range(xxx, kva, xxx)
It failed because that the check for page_count(page) is null so return, it
break the some logic for current modules.
because the new huge page is not valid for composed page.

The function did not be used any more, so remove it.

Use the recently added and possibly more efficient
ether_addr_equal_unaligned to instead of memcmp.
