Subject: [Qemu-devel] [PATCH v2 09/19] exec.c: Use cpu_get_phys_page_attrs_debug
Date: Mon, 16 Nov 2015 14:05:13 +0000	[thread overview]
Message-ID: <1447682723-3977-10-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1447682723-3977-1-git-send-email-peter.maydell@linaro.org>

Use cpu_get_phys_page_attrs_debug() when doing virtual-to-physical
conversions in debug related code, so that we can obtain the right
address space index and thus select the correct AddressSpace,
rather than always using cpu->as.
