scsi: message: mptfc: Switch from pci_ to dma_ API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag. It has been compile
tested.
When memory is allocated in 'mptfc_GetFcDevPage0()' GFP_KERNEL can be used
because it is already used in this function and no lock is acquired in the
between.
When memory is allocated in 'mptfc_GetFcPortPage0()' and
'mptfc_GetFcPortPage1()' GFP_KERNEL can be used because they already call
'mpt_config()' which has an explicit 'might_sleep()'.

After a REPORT LUN command issued to the offline device fails, the SCSI
midlayer tries to do a sequential scan of all devices whose LUN number is

Introduce a generic sas_slave_alloc() handler which will return -ENXIO for
SATA devices if the requested LUN number is larger than 0 and make libsas
drivers use this function as their .slave_alloc callback.

When this occurs during error handling, the current policy is to allow

the required reset.
However various steps of error handling need to taken before this happens.
These also involve some level of HW interaction, which will also fail with

Speed up this process by recording a HW fault bit for an internal abort
timeout - when this is set, just automatically error any HW interaction,
