Merge tag 'for-linus-5.0' of git://github.com/cminyard/linux-ipmi

Pull IPMI fixes from Corey Minyard:
 "I missed the merge window, which wasn't really important at the time
  as there was nothing that critical that I had for 5.0.

  However, I say that,and then a number of critical fixes come in:

   - ipmi: fix use-after-free of user->release_barrier.rda
   - ipmi: Prevent use-after-free in deliver_response
   - ipmi: msghandler: Fix potential Spectre v1 vulnerabilities

  which are obvious candidates for 5.0.  Then there is:

   - ipmi:ssif: Fix handling of multi-part return messages

  which is less critical, but it still has some off-by-one things that
  are not great, so it seemed appropriate. Some machines are broken
  without it. Then:

   - ipmi: Don't initialize anything in the core until something uses it

  It turns out that using SRCU causes large chunks of memory to be used
  on big iron machines, even if IPMI is never used. This was causing
  some issues for people on those machines.

  Everything here is destined for stable"
