[Qemu-devel] [PULL 15/36] exec.c: Add cpu_get_address_space() |
Date: |
Thu, 21 Jan 2016 14:56:08 +0000 |
Add a function to return the AddressSpace for a CPU based on
its numerical index. (Callers outside exec.c don't have access
to the CPUAddressSpace struct so can't just fish it out of the
CPUState struct directly.)
