I don't know exactly how this translates to Linux internals, but most

this for once and for all.
So to summarize my two mails: I think te use of dma_get_required_mask
in mpt3sas is wrong, and the dma_get_required_mask return value from
xen-swiotlb is also wrong. Fixing either one should fix this problem,
and I think we should fix both.
Hi all,
Is there anything that can be done to get this fixed in xen and the kernel somehow?
I keep having to manually patch the mpt3sas driver to prevent it from being able to switch to 32bit mode each time I upgrade the kernel.
