H A D | mce.h | b63a0ffe Wed Oct 30 09:36:13 CDT 2013 Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com> powerpc/powernv: Machine check exception handling.
Add basic error handling in machine check exception handler.
- If MSR_RI isn't set, we can not recover. - Check if disposition set to OpalMCE_DISPOSITION_RECOVERED. - Check if address at fault is inside kernel address space, if not then send SIGBUS to process if we hit exception when in userspace. - If address at fault is not provided then and if we get a synchronous machine check while in userspace then kill the task.
