[Qemu-devel] [PATCH 0/4] exec: address space translation cleanups

[Peter Xu]

The problem is that, address_space_get_iotlb_entry() shares a lot with
address_space_translate(). This patch tries to abstract the
shared elements.

Originally, this work is derived from discussion from VT-d passthrough
series discussions [1]. But for sure we can just see this series as a
standalone cleanup. So I posted it separately here.

Smoke tests are done with general VM boots, IOs, especially with vhost
dmar configurations.

I believe with current series I can throw away the old patch [1],
which may be good. But before that, please kindly review. Thanks.
