Series iommu: add MemTxAttrs argument to IOMMU translate function | expand

Commit Message

Peter Maydell May 1, 2018, 8:59 a.m. UTC 
As part of plumbing MemTxAttrs down to the IOMMU translate method,
add MemTxAttrs as an argument to tb_invalidate_phys_addr().
Its callers either have an attrs value to hand, or don't care
and can use MEMTXATTRS_UNSPECIFIED.
