V9: 1. Fixed 2 improvements suggested by the kbuild test robot. 1.1 Change ghes_gdata_pool_init() as static function. 1.2. Removed using buffer to store the error data for logging in the hisi_pcie_handle_error() V8: 1. Removed reporting the standard errors through the interface because of the conflict with the recent patches in the memory error handling path. 2. Fix comments by Dan Carpenter. V7: 1. Add changes in the APEI driver suggested by Borislav Petkov, for queuing up all the non-fatal HW errors to the work queue and notify the registered kernel drivers from the bottom half using blocking notifier, common interface for both standard and vendor-spcific errors. 2. Fix for further feedbacks in v5 HIP PCIe error handler driver by Bjorn Helgaas. V6: 1. Fix few changes in the patch subject line suggested by Bjorn Helgaas. V5: 1. Fix comments from James Morse. 1.1 Changed the notification method to use the atomic_notifier_chain. 1.2 Add the error handled status for the user space. V4: 1. Fix for the following smatch warning in the PCIe error driver, reported by kbuild test robot: 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.
