2016-09-23EDAC, altera: Add IRQ Flags to disable IRQ while handlingThor Thayer1-8/+10
Add the IRQF_ONESHOT and IRQF_TRIGGER_HIGH flags to disable the IRQ while executing the IRQ handler. Remove the IRQF_SHARED because these are not shared IRQs in the domain. Exposed when flooding IRQs.

2016-09-13x86/MCE/AMD, EDAC: Handle reserved bank 4 on Fam17h properlyYazen Ghannam1-0/+3
Bank 4 is reserved on family 0x17 and shouldn't generate any MCE records. However, broken hardware and software is not something unheard of so warn about bank 4 errors. They shouldn't be coming from bank 4 naturally but users can still use mce_amd_inj to simulate errors from it for testing purposed. Also, avoid special handling in the injector mce_amd_inj like it is being done on the older families. [ bp: Rewrite commit message and merge into one patch.

2016-09-13x86/mce, EDAC/mce_amd: Print MCA_SYND and MCA_IPID during MCE on SMCA systemsYazen Ghannam1-0/+2
The MCA_SYND and MCA_IPID registers contain valuable information and should be included in MCE output. The MCA_SYND register contains syndrome and other error information, and the MCA_IPID register will uniquely identify the MCA bank's type without having to rely on system software.

2016-09-13x86/mce/AMD, EDAC/mce_amd: Define and use tables for known SMCA IP typesYazen Ghannam1-158/+36
Scalable MCA defines a number of IP types. An MCA bank on an SMCA system is defined as one of these IP types. A bank's type is uniquely identified by the combination of the HWID and MCATYPE values read from its MCA_IPID register. Add the required tables in order to be able to lookup error descriptions based on a bank's type and the error's extended error code.
