Raghava Aditya Renukunta 0e9973ed33 scsi: aacraid: Add periodic checks to see IOP reset status
Added function that waits with a timeout for the ctrl to be up and running
after triggering an IOP reset. Also removed 30 sec sleep as it is not
needed.

Guilherme G. Piccoli 911e572e98 scsi: aacraid: fix PCI error recovery path
During a PCI error recovery, if aac_check_health() is not aware that a
PCI error happened and we have an offline PCI channel, it might trigger
some errors (like NULL pointer dereference) and inhibit the error
recovery process to complete.

This patch makes the health check procedure aware of PCI channel issues,
and in case of error recovery process, the function
aac_adapter_check_health() returns -1 and let the recovery process to
complete successfully. This patch was tested on upstream kernel
v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d
(VID:DID) - the error recovery procedure was able to recover fine.

Currently driver checks the health status of the adapter once every 24
hours. When that happens the driver becomes dependent on the kernel to
figure out if the  adapter is misbehaving. This might take some time
(when the adapter is idle). The driver currently has support to
restart/recover the controller when it fails, and decreasing the time
interval will help.

Raghava Aditya Renukunta a7e2c64284 scsi: aacraid: Fix sync fibs time out on controller reset
After controller shutdown, all sync fibs time out due to not knowing
about the switch to INT-x mode

Fixed by replacing aac_src_access_devreg() to aac_set_intx_mode() call.

Raghava Aditya Renukunta 16ae9dd35d scsi: aacraid: Fix for excessive prints on EEH
This issue showed up on a kdump debug(single CPU on powerkvm), when EEH
errors rendered the adapter unusable. The driver correctly detected the
issue and attempted to restart the controller, in doing so the driver
attempted to read the status registers of the controller. This triggered
additional eeh errors which continued for a good 6 minutes.

Fixed by returning without waiting when EEH error is reported.

Arnd Bergmann 80a94bb357 scsi: aacraid: avoid open-coded upper_32_bits
Shifting a dma_addr_t right by 32 bits causes a compile-time warning
when that type is only 32 bit wide:

drivers/scsi/aacraid/src.c: In function 'aac_src_start_adapter':
drivers/scsi/aacraid/src.c:414:29: error: right shift count >= width of type [-Werror=shift-count-overflow]

This changes the driver to use the predefined macros consistently,
including one correct but open-coded upper_32_bits() instance.
