From f26404fbeef33ac8798d2541839f7873bbae91fd Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 31 May 2018 14:50:52 +0100 Subject: Make address_space_map() take a MemTxAttrs argument As part of plumbing MemTxAttrs down to the IOMMU translate method, add MemTxAttrs as an argument to address_space_map(). Its callers either have an attrs value to hand, or don't care and can use MEMTXATTRS_UNSPECIFIED.
