We currently handle 32-bit accesses to trapped VM system registers using the 32-bit index into the coproc array on the vcpu structure, which is a union of the coproc array and the sysreg array. Since all the 32-bit coproc indices are created to correspond to the architectural mapping between 64-bit system registers and 32-bit coprocessor registers, and because the AArch64 system registers are the double in size of the AArch32 coprocessor registers, we can always find the system register entry that we must update by dividing the 32-bit coproc index by 2. This is going to make our lives much easier when we have to start accessing system registers that use deferred save/restore and might have to be read directly from the physical CPU.
