Title:
  NX842 fixes for Ubuntu 15.10

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Wily:
  Fix Released

Bug description:
  ---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.
