NX842 fixes for Ubuntu 15.10

[bugproxy]

---Problem Description---
There are actually some more NX 842 patches that should be in the 4.3 kernel. They're currently all in Herbert's tree:
git://git.kernel.org/pub/scm/linux/kernel/git/herbert/cryptodev-2.6.git

In the usual descending order:

03952d9 crypto: nx - make platform drivers directly register with crypto
174d66d crypto: nx - rename nx-842-crypto.c to nx-842.c
d31581a crypto: nx - merge nx-compress and nx-compress-crypto
20fc311 crypto: nx - use common code for both NX decompress success cases
ee781b7 crypto: nx - don't register pSeries driver if ENODEV
7f6e3aa crypto: nx - move kzalloc() out of spinlock
90fd73f crypto: nx - remove pSeries NX 'status' field
039af96 crypto: nx - remove __init/__exit from VIO functions
23ad69a crypto: nx/842 - Fix context corruption
2b93f7e crypto: nx - reduce chattiness of platform drivers
7abd75b crypto: nx - do not emit extra output if status is disabled
ec13bcb crypto: nx - rename nx842_{init, exit} to nx842_pseries_{init, exit}
fa9a9a0 crypto: nx - nx842_OF_upd_status should return ENODEV if device is not 'okay'

---uname output---
Ubuntu 15.10

Machine Type = power 8

I am working on back-port these patches and will be providing them early next week. These patches fix several bugs in nx842 code.

We should have time to pick these from upstream once the 4.3 merge window opens.

Thanks, So I will not provide back-ports for all 13 patches. Please let me know if you expect patches from me.
