From 4cbea5986981998cda07b13794c7e3ff7bc42e80 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Mon, 24 Aug 2015 01:42:07 +0200 Subject: linux-user: remove --enable-guest-base/--disable-guest-base All tcg host architectures now support the guest base and as there is no real performance lost, it can be always enabled. Anyway, guest base use can be disabled lively by setting guest base to 0. CONFIG_USE_GUEST_BASE is defined as (USE_GUEST_BASE && USER_ONLY), it should have to be replaced by CONFIG_USER_ONLY in non CONFIG_USER_ONLY parts, but as some other parts are using !CONFIG_SOFTMMU I have chosen to use !CONFIG_SOFTMMU instead.
