/* This module creates and removes signal frames for signal deliveries
on amd64-linux.
FIXME: Note that this file is in the wrong place. It is marked as
amd64 specific, but in fact it is specific to both amd64 and linux.
There is nothing that ensures that (eg) amd64-netbsd will have the
same signal frame layout as Linux.
Note also, this file contains kernel-specific knowledge in the
form of 'struct rt_sigframe'. How does that relate to the vki
kernel interface stuff?

A 'struct rtsigframe' is pushed onto the client's stack. This
contains a subsidiary vki_ucontext. That holds the vcpu's state
