[Linux-ia64] test10 bug on SW IO TLB

Hi,

there seems to be a bug on software IO TLB buffer.

Kernel command line option `swiotlb=' is ignored
when the bounce buffer for SW IO TLB is allocated.

Following is a patch to this.
But the call to setup_swiotlb should be in some file in
arch/ia64/kernel/ , i guess.
