KlogAcpiObjectDoesNotExist errors for possible investigation

[Kent Baxley]

I hit these while testing a Dell PowerEdge M910 and just want to make sure they aren't anything bad. We are running 14.04 with the latest 3.13.0-23-generic kernel:

FAILED [HIGH] KlogAcpiObjectDoesNotExist: Test 1, HIGH Kernel message: [
22.414781] ACPI Error: Method parse/execution failed [\_SB_.PMI0._GHL] (Node
ffff8820294b53e8), AE_NOT_EXIST (20131115/psparse-536)

ADVICE: The ACPI interpreter failed to execute or parse some AML because a
object or control did not exist. This normally occurs because of buggy firmware
and may lead to unexpected behaviour or loss of functionality.

It seems the kernel driver that implements calls _PMC & _GHL does not implement OpreationRegion, and therefore accessing it generates failures. If such functions are needed, one must implement it in the kernel.

I don't think anyone is using BIOS interface to manage IPMI at the moment, and therefore this is not a problem.
