Same here. So unless I miss something, we better have a separate
NT_ORIGREG (or some better name) regset to retrieve the additional
registers. Or, if you want to get all of them in one go, just add a
new one similar to NT_PRSTATUS but which restores x0 to orig_x0 and x7
to orig_x7.
Sorry if this was already discussed. I had a brief look at the previous
versions and couldn't see a user_pt_regs structure change, nor a
suggestion to do so.
