2021-06-13tcg: Fix documentation for tcg_constant_* vs tcg_temp_free_*Richard Henderson1-1/+2
At some point during the development of tcg_constant_*, I changed my mind about whether such temps should be able to be passed to tcg_temp_free_*. The final version committed allows this, but the commentary was not updated to match.

There's a change in mprotect() behaviour [1] in the latest macOS on M1 and it's not yet clear if it's going to be fixed by Apple. In this case, instead of changing permissions of N guard pages, we change permissions of N rwx regions. The same number of syscalls are required either way.

Shortly, the full code_gen_buffer will only be visible to region.c, so move in_code_gen_buffer out-of-line. Move the debugging versions of tcg_splitwx_to_{rx,rw} to region.c as well, so that the compiler gets to see the implementation of in_code_gen_buffer.

2021-06-11vhost-vdpa: don't initialize backend_featuresJason Wang1-3/+0
We used to initialize backend_features during vhost_vdpa_init() regardless whether or not it was supported by vhost. This will lead the unsupported features like VIRTIO_F_IN_ORDER to be included and set to the vhost-vdpa during vhost_dev_start. Because the VIRTIO_F_IN_ORDER is not supported by vhost-vdpa so it won't be advertised to guest which will break the datapath. Fix this by not initializing the backend_features, so the acked_features could be built only from guest features via vhost_net_ack_features().
