[Qemu-stable] [PATCH 06/55] exec: Explicitly export target AS from address_space_translate_internal |
Date: |
Wed, 6 Dec 2017 13:15:59 -0600 |
From: Alexey Kardashevskiy <address@hidden>
This adds an AS** parameter to address_space_do_translate()
to make it easier for the next patch to share FlatViews.
This should cause no behavioural change.
