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. In all these places where some memory is allocated GFP_KERNEL can be used because they already call 'mpt_config()' which has an explicit 'might_sleep()'. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3;

The only caller of 'mptsas_exp_repmanufacture_info()' is 'mptsas_probe_one_phy()'. This function already calls 'sas_end_device_alloc()' or 'sas_expander_alloc()'. They both already use GFP_KERNEL. As no spin_lock is held at this point, it is safe to also use GFP_KERNEL here. While at it, also fix an ugly alignment issue in this function.
