[PATCH v2 0/2] MR3365: ntdll: Pass the trampoline ctx to the exception dispatcher on aarch64.

[Billy Laws (＠bylaws)]

CFI directives allow the context stored on the stack by raise_func_trampoline
to be used to unwind to any exception handlers as required when dispatching
an exception. As the dispatcher may change its input context in e.g.
BTCpuResetToConsistentState and these changes also need to be used when
unwinding make sure to pass this copy of the context to
KiUserExceptionDispatcher as opposed to the copy initially stored on the stack,
which is not taken into account when unwinding.
