[Qemu-devel] [PATCH target-arm v1 1/2] arm: armv7m: Rename address_space_mem -> system_memory

[Peter Crosthwaite]

This argument is a MemoryRegion and not an AddressSpace.

"Address space" means something quite different to "memory region"
in QEMU parlance so rename the variable to reduce confusion.
