[PATCH] ipmi: OEM flag handling and hacks for some Dell machines
The ipmi driver does not have a way to handle firmware-generated events which have the OEM[012] Data Available flags set. In such a case, the SMS_ATN bit may never get cleared by firmware, leaving the driver looping infinitely but never able to make any progress. This patch first simplifies storage and use of the data returned from an IPMI Get Device ID command. It then creates a new per-OEM handler hook, which should know how to handle events with the OEM[012] Data Available flags set. It then uses this to implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which are susceptable to setting the OEM[012] Data Available flags when the driver can't handle it.
