Shiju Jose b7765b0a03 ACPI: APEI: Fix AER info corruption when error status data has multiple sections ... [ Upstream commit e2abc47a5a ] ghes_handle_aer() passes AER data to the PCI core for logging and recovery by calling aer_recover_queue() with a pointer to struct aer_capability_regs. The problem was that aer_recover_queue() queues the pointer directly without copying the aer_capability_regs data. The pointer was to the ghes->estatus buffer, which could be reused before aer_recover_work_func() reads the data. To avoid this problem, allocate a new aer_capability_regs structure from the ghes_estatus_pool, copy the AER data from the ghes->estatus buffer into it, pass a pointer to the new struct to aer_recover_queue(), and free it after aer_recover_work_func() has processed it.
