The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext).
Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC). The CPU uses the CPUExecContext, or however else it stores its own state. It then creates a ProxyExecContext, templated on the class used to hold its state. This proxy is passed to any code outside of the CPU that needs to access the XC. This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out.
Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.

Make the AlphaConsole calculate the number of CPUs instead
of passing that in as a parameter.
cpu/base.cc:
pass the desired cpu_id into registerExecContext, offsetting it
by the thread number. a cpu_id of -1 means that it should be
generated for you.

cpu/o3/alpha_cpu_builder.cc:
cpu/simple/cpu.cc:
Accept the cpu_id as a parameter
while we're here, let's remove the multiplier since it is
not used.
dev/alpha_console.cc:
don't take the number of CPUs as a parameter. Calculate it from
the system based on the number of CPUs that have been registered.
move init() code to startup() to ensure that all CPUs are registerd.

already used. Accept -1 as a request to have an id assigned.

that checks to ensure that they are all registered correctly.
