Detailed Description

ISA-specific helper functions for locked memory accesses.

Note that these functions are not embedded in the ISA description because they operate on the physical address rather than the virtual address. In the current M5 design, the physical address is not accessible from the ISA description, only from the CPU model. Thus the CPU is responsible for calling back to the ISA (here) after the address translation has been performed to allow the ISA to do these manipulations based on the physical address.
