Just to let you know, I'm taking some of these patches into a series I'm working on for multiple address-space support (for ARM trustzone). Basically I'm taking patches 2 and 3, plus a variant of patch 5 that avoids the need to make cpu.o an obj-y object. Then I have some more patches of my own which add an extra QOM property for ARM CPUs for the secure-memory address space. Alpha-quality work-in-progress patches currently at https://git.linaro.org/people/peter.maydell/qemu-arm.git multi-ases web view: https://git.linaro.org/people/peter.maydell/qemu-arm.git/shortlog/refs/heads/multi-ases I'm not completely certain about the AS reference-counting code right now; will have to come back and think harder about it later. thanks -- PMM
