Subject: [PATCH 0/1] scsi: mptctl: Remove usage of the deprecated "pci-dma-compat.h" API

This cover letter is only there to draw attention on the fact that I'm a bit
unsure about the use of GFP_KERNEL in 'kbuf_alloc_2_sgl()'.

In all conversion that I've done, GFP_USER was never used. I don't fully
understand the difference between GFP_USER and GFP_KERNEL.

So please review with care.

For the 3 other functions, I'm much more confident. I've put the explanation
of why I think that GFP_KERNEL is safe in patch 1/1.
Basically, these functions already call some functions that can sleep.
