From 37448adfc7ce0d6d5892b87aa8d57edde4126f49 Mon Sep 17 00:00:00 2001 From: Lance Ortiz Date: Thu, 30 May 2013 08:25:12 -0600 Subject: aerdrv: Move cper_print_aer() call out of interrupt context The following warning was seen on 3.9 when a corrected PCIe error was being handled by the AER subsystem. WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90() This occurred because a call to pci_get_domain_bus_and_slot() was added to cper_print_pcie() to setup for the call to cper_print_aer(). The warning showed up because cper_print_pcie() is called in an interrupt context and pci_get* functions are not supposed to be called in that context. The solution is to move the cper_print_aer() call out of the interrupt context and into aer_recover_work_func() to avoid any warnings when calling pci_get* functions.
