I do not expect that anything should be changed or could break for x86_64.
My concern is about Linux on ARM and possibly QNX.

The patch is available at
branch for-arun commit 5fd04f7f26a5de726

I remember that there were several issues not finalized when I worked on this:
1. I extended unw_tdep_frame_t frame_type bit width, so structure take
one more word.  This may be acceptable.
2. I did not re-checked the FreeBSD sigframe layout constants AFAIR.
3. Some tests segfault.

I tried the port with my pstacku code and it worked for my use.
