From 651a5bc03705102de519ebf079a40ecc1da991db Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 21 Jan 2016 14:15:05 +0000 Subject: [PATCH] exec.c: Add cpu_get_address_space() 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.) Signed-off-by: Peter Maydell Acked-by: Edgar E.
