This patch set 1. add an interface to the APEI driver to enable the vendor drivers to register the event handling functions for the corresponding vendor specific HW errors and report the error to the vendor driver. 2. add driver to handle HiSilicon hip08 PCIe controller's errors which is an example application of the above APEI interface. Changes: V4: 1. Fix for the smatch warning in the PCIe error driver: warn: should '((((1))) << (9 + i))' be a 64 bit type? if (err->val_bits & BIT(HISI_PCIE_LOCAL_VALID_ERR_MISC + i)) ^^^ This should be BIT_ULL() because it goes up to 9 + 32. V3: 1. Fix the comments from Bjorn Helgaas. V2: 1. Changes in the HiSilicon PCIe controller's error handling driver for the comments from Bjorn Helgaas. 2. Changes in the APEI interface to support reporting the vendor error for module with multiple devices, but use the same section type. In the error handler will use socket id/sub module id etc to distinguish the device. V1: 1. Fix comments from James Morse. 2. add driver to handle HiSilicon hip08 PCIe controller's errors, which is an application of the above interface.
