[Qemu-devel] [PATCH v2 10/19] exec.c: Use correct AddressSpace in watch_mem_read and watch_mem_write

[Peter Maydell <peter.maydell@linaro.org>]

In the watchpoint access routines watch_mem_read and watch_mem_write,
find the correct AddressSpace to use from current_cpu and the memory
transaction attributes, rather than always assuming address_space_memory.
