Subject: [PATCH] kvm: expose struct KVMState

from mainline-v7.2.0-rc0
commit 5f8a6bce1f1080058ed29d716cae81ea805142ae
category: feature
feature: Notify VM Exit
bugzilla: https://gitee.com/openeuler/intel-qemu/issues/I6GWQE

Intel-SIG: commit 5f8a6bce1f10 ("kvm: expose struct KVMState")

------------------------------------------------------------------

kvm: expose struct KVMState

Expose struct KVMState out of kvm-all.c so that the field of struct
KVMState can be accessed when defining target-specific accelerator
properties.
