Subject: [PATCH] Documentation: Add "S390" to the swiotlb kernel parameter
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.
Signed-off-by: Thomas Huth <thuth@...hat.com>

PS: I wonder whether we could remove IA-64 nowadays...?
