Last round of updates for net-next:
 * revert a patch that caused a regression with mesh userspace (Bob)
 * fix a number of suspend/resume related races
   (from Emmanuel, Luca and myself - we'll look at backporting later)
 * add software implementations for new ciphers (Jouni)
 * add a new ACPI ID for Broadcom's rfkill (Mika)
 * allow using netns FD for wireless (Vadim)
 * some other cleanups (various)
