This series of patches adds support of the HBA mode on HP Smart Array P410i RAID controllers.
This is not guaranteed to be correct as I do not have any access to documentation on these controllers. However, this works fine for me on hardware that I have. Also, these changes successfully passes blktests[1] and xfstests[2]. To make sure that this new functionality does not break anything, it is disabled by default and may be enabled only manually using new module parameter.
