[ Upstream commit 07de4bc88ce6a4d898cad9aa4c99c1df7e87702d ]
In a regular interrupt handler driver was finishing the crypt/decrypt
request by calling complete on crypto request. This is disallowed since
converting to skcipher in commit b286d8b1a690 ("crypto: skcipher - Add
skcipher walk interface") and causes a warning:
WARNING: CPU: 0 PID: 0 at crypto/skcipher.c:430 skcipher_walk_first+0x13c/0x14c
The interrupt is marked shared but in fact there are no other users
sharing it. Thus the simplest solution seems to be to just use a
threaded interrupt handler, after converting it to oneshot.

commit 2b163b5bce04546da72617bfb6c8bf07a45c4b17 upstream. This reverts commit 66d2e2028091a074aa1290d2eeda5ddb1a6c329c. Quoting from Russell's findings: https://www.mail-archive.com/linux-crypto@vger.kernel.org/msg21136.html [quote] Okay, I've re-tested, using a different way of measuring, because using openssl speed is impractical for off-loaded engines. I've decided to use this way to measure the performance: dd if=/dev/zero bs=1048576 count=128 | /usr/bin/time openssl dgst -md5 For the threaded IRQs case gives: 0.05user 2.74system 0:05.30elapsed 52%CPU (0avgtext+0avgdata 2400maxresident)k 0.06user 2.52system 0:05.18elapsed 49%CPU (0avgtext+0avgdata 2404maxresident)k 0.12user 2.60system 0:05.61elapsed 48%CPU (0avgtext+0avgdata 2460maxresident)k => 5.36s => 25.0MB/s and the tasklet case: 0.08user 2.53system 0:04.83elapsed 54%CPU (0avgtext+0avgdata 2468maxresident)k 0.09user 2.47system 0:05.16elapsed 49%CPU (0avgtext+0avgdata 2368maxresident)k 0.10user 2.51system 0:04.87elapsed 53%CPU (0avgtext+0avgdata 2460maxresident)k => 4.95 => 27.1MB/s which corresponds to an 8% slowdown for the threaded IRQ case. So, tasklets are indeed faster than threaded IRQs. [...] I think I've proven from the above that this patch needs to be reverted due to the performance regression, and that there _is_ most definitely a deterimental effect of switching from tasklets to threaded IRQs.

[ Upstream commit 8759fec4af222f338d08f8f1a7ad6a77ca6cb301 ]
Currently, inner IV/DIGEST data are only copied once into the hash
engines and not set explicitly before launching a request that is not a
first frag. This is an issue especially when multiple ahash reqs are
computed in parallel or chained with cipher request, as the state of the
request being computed is not updated into the hash engine. It leads to
non-deterministic corrupted digest results.

[ Upstream commit 7dede913fc2ab9c0d3bff3a49e26fa9e858b0c13 ] Some preemptible check warnings were reported from enable_kernel_vsx(). This patch disables preemption in aes_ctr.c before enabling vsx, and they are now consistent with other files in the same directory.
