摘要：
A computer-implemented method for switching between a full space and a subspace across multiple address spaces is described. A non-limiting example of the computer-implemented method includes determining, by a processor, that switching between the full space and the subspace is enabled by examining a bit in a control register. The method determines, by the processor, that there is a new context different from an existing context based on the bit in the control register indicating that switching is enabled and switches, by the processor, the context of the multiple spaces based on determining that the new context is different from the existing context.
