cpu-exec: fix lock hierarchy for user-mode emulation
tb_lock has to be taken inside the mmap_lock (example: tb_invalidate_phys_range is called by target_mmap), but tb_link_page is taking the mmap_lock and it is called with the tb_lock held. To fix this, take the mmap_lock in tb_find_slow, not in tb_link_page. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
