BTW, 1310724 seems to be 131072 * 10 + 4 rather than +1 as the comment
claims. I wonder why I made that mistake.

No, if the kernel is larger than 1310724 it won't get padded but this
is not important since slugimage needs to round up to a full block
anyway, and 1310724 is more than 10 blocks so it will take 11 blocks,
which is what we want
Apparently slugimage allocates 11 blocks when you give it a file with
1310705 bytes. This makes sense since 131072 * 10 - 16 = 1310704
(- 16 because of the header).
In summary, I believe any value between 1310705 and 1441776 will work.
Right, I just tested this. Maybe we should pad to 1310705 then.
