[PATCH] Documentation: Add "S390" to the swiotlb kernel parameter

[PATCH] Documentation: Add "S390" to the swiotlb kernel parameter

[Thomas Huth]

The "swiotlb" kernel parameter is used on s390 for protected virt since
commit 64e1f0c531d1 ("s390/mm: force swiotlb for protected virtualization")
and thus should be marked in kernel-parameters.txt accordingly.

Applied, thanks.

For the record, this is a great set of cleanups, thanks for doing this.

Yes, references to IA-64 should come out at this point.  If you want to
do that, I'd suggest doing it as one big patch...  in theory, that
architecture could come back if enough maintenance initiative is shown.
I don't think it will happen but, if it does, it would be nice to be
able to undo the docs change with a single revert.

Thanks,
