[Qemu-devel] [PULL 16/36] exec.c: Use cpu_get_phys_page_attrs_debug

[Peter Maydell <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.
