From 07bdaa4196b51bc7ffa7c3f74e9e4a9dc8a7966a Mon Sep 17 00:00:00 2001 From: Paolo Bonzini <pbonzini@redhat.com> Date: Fri, 25 Mar 2016 12:55:08 +0100 Subject: memory: split memory_region_from_host from qemu_ram_addr_from_host MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the old qemu_ram_addr_from_host to memory_region_from_host and make it return an offset within the region. For qemu_ram_addr_from_host return the ram_addr_t directly, similar to what it was before commit 1b5ec23 ("memory: return MemoryRegion from qemu_ram_addr_from_host", 2013-07-04).
