[Qemu-devel] [PATCH Part1 2/5] acpi, ich9: Add hotunplug request cb for ich9. |
Date: |

Memory and CPU hot unplug are both asynchronize procedures.
They both need unplug request cb when the unplug operation happens.
This patch adds hotunplug request cb for ich9, and memory and CPU
hot unplug will base on it.
