2016-05-06cxlflash: Fix to resolve dead-lock during EEH recoveryManoj N. Kumar
When a cxlflash adapter goes into EEH recovery and multiple processes (each having established its own context) are active, the EEH recovery can hang if the processes attempt to recover in parallel. The symptom logged after a couple of minutes is: INFO: task eehd:48 blocked for more than 120 seconds. Not tainted 4.5.0-491-26f710d+ #1 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. eehd 0 48 2 Call Trace: __switch_to+0x2f0/0x410 __schedule+0x300/0x980 schedule+0x48/0xc0 rwsem_down_write_failed+0x294/0x410 down_write+0x88/0xb0 cxlflash_pci_error_detected+0x100/0x1c0 [cxlflash] cxl_vphb_error_detected+0x88/0x110 [cxl] cxl_pci_error_detected+0xb0/0x1d0 [cxl] eeh_report_error+0xbc/0x130 eeh_pe_dev_traverse+0x94/0x160 eeh_handle_normal_event+0x17c/0x450 eeh_handle_event+0x184/0x370 eeh_event_handler+0x1c8/0x1d0 kthread+0x110/0x130 ret_from_kernel_thread+0x5c/0xa4 INFO: task blockio:33215 blocked for more than 120 seconds.

The hang is because of a 3 way dead-lock: Process A holds the recovery mutex, and waits for eehd to complete. Process B holds the semaphore and waits for the recovery mutex. eehd waits for semaphore. The fix is to have Process B above release the semaphore before attempting to acquire the recovery mutex. This will allow eehd to proceed to completion. Signed-off-by: Manoj N.

2016-04-29aacraid: Fix for KDUMP driver hangRaghava Aditya Renukunta
When KDUMP is triggered the driver first talks to the firmware in INTX mode, but the adapter firmware is still in MSIX mode. Therefore the first driver command hangs since the driver is waiting for an INTX response and firmware gives a MSIX response. If when the OS is installed on a RAID drive created by the adapter KDUMP will hang since the driver does not receive a response in sync mode. Fixed by: Change the firmware to INTX mode if it is in MSIX mode before sending the first sync command.

2016-04-29aacraid: Fix for aac_command_thread hangRaghava Aditya Renukunta
Typically under error conditions, it is possible for aac_command_thread() to miss the wakeup from kthread_stop() and go back to sleep, causing it to hang aac_shutdown. In the observed scenario, the adapter is not functioning correctly and so aac_fib_send() never completes (or time-outs depending on how it was called). Shortly after aac_command_thread() starts it performs aac_fib_send(SendHostTime) which hangs. When aac_probe_one /aac_get_adapter_info send time outs, kthread_stop is called which breaks the command thread out of it's hang. The code will still go back to sleep in schedule_timeout() without checking kthread_should_stop() so it causes aac_probe_one to hang until the schedule_timeout() which is 30 minutes.

2016-04-29aacraid: Relinquish CPU during timeout waitRaghava Aditya Renukunta
aac_fib_send has a special function case for initial commands during driver initialization using wait < 0(pseudo sync mode). In this case, the command does not sleep but rather spins checking for timeout.This loop is calls cpu_relax() in an attempt to allow other processes/threads to use the CPU, but this function does not relinquish the CPU and so the command will hog the processor. This was observed in a KDUMP "crashkernel" and that prevented the "command thread" (which is responsible for completing the command from being timed out) from starting because it could not get the CPU.
