Impact: The driver code changed in 3.19 to do periodic checks on irq and message settings
  commit d9b7e4f717a167610a49ceb9e5969e80146c89a8
  ipmi: Periodically check to see if irqs and messages are set right
This causes repeated error messages in the logs for certain BMCs which do not allow to disable the irq mode in the global config even when they do not support irqs.

Fix: Cherry-pick upstream commit
1e7d6a45f6b10bc48a1453bca3d829e210546571 which adds a quirk to detect
this situation and avoids touching those bits. This was done in 4.0, so
the only affected kernel is 3.19.

Testcase: With an affected BMC and without the patch, errors repeatedly
get logged. With the patch applied, there will be only a single message
in the log.

Bug description:
  Hello,

  after upgrading my system to 14.04.3 LTS and installing the Vivid-LTS-
  Enablement-Stack the kernel log of my system is spammed with the
  following message by the "impi_si" kernel module:

  ...
  [ 2268.244383] ipmi_si 00:05: Could not set the global enables: 0xcc.
  [ 2269.451974] ipmi_si 00:05: Could not set the global enables: 0xcc.
  [ 2270.252290] ipmi_si 00:05: Could not set the global enables: 0xcc.
  [ 2271.452749] ipmi_si 00:05: Could not set the global enables: 0xcc.
  [ 2272.253057] ipmi_si 00:05: Could not set the global enables: 0xcc.
  ...

  This bug is already known to the ipmi_si kernel module maintainer and
  seems to be fixed in 4.0+ kernels.

  Is it possible to backport this fix to the Vivid 3.19 kernel?

  Please see this mail thread: https://www.mail-archive.com/openipmi-
  developer@xxxxxxxxxxxxxxxxxxxxx/msg02425.html

  IPMI functionality seems to be unaffected by this bug but as I said it
  spams the kernel log and that is rather annoying.
