[PATCH] crypto: blkcipher_get_spot() handling of buffer at end of page
This corresponds to upstream changesets
e4630f9fd8cdc14eb1caa08dafe649eb5ae09985 and
32528d0fbda1093eeeaa7d0a2c498bbb5154099d.
[CRYPTO] blkcipher: Fix handling of kmalloc page straddling
The function blkcipher_get_spot tries to return a buffer of
the specified length that does not straddle a page. It has
an off-by-one bug so it may advance a page unnecessarily.
What's worse, one of its callers doesn't provide a buffer
that's sufficiently long for this operation.
This patch fixes both problems. Thanks to Bob Gilligan for
diagnosing this problem and providing a fix.
