In Some error cases the application can need to release it instead of sending it to the remote side. As the virtqueue is updated when the buffer it get, it is not possible to manage this use case at virtqueue level. This patchset implements the release based on a buffer recycler. The principle is to store the released buffer in a 'reclaimer' list. On next get pmsg_virtio_get_tx_buffer call the buffer is reused.

This was because the call to copy_from_shbuf() was now inlined by the optimizer and the compiler generated code that used 8-byte copies ("ldp x10, x11 [x4, #16]" followed by the corresponding store instruction). The bus error happened when the address in x4 (the index) was 4-byte aligned, but not 8-byte aligned. This would not be a problem with normal user-space memory, but the memory used for the shared buffer between the remote processor and Linux is mapped as device memory. On AArch64, device memory is strictly ordered and the alignment and width of accesses must match. Replace copy_from_shbuf() with a call to metal_io_block_read(), which is intended to do this sort of thing, and also makes this a better example of how to use OpenAMP. Return error only on a negative return value from copy_from_shbuf in rpmsg_endpoint_cb.
