Summary
In the Linux kernel, the following vulnerability has been resolved:
RISC-V: KVM: Teardown riscv specific bits after kvm_exit
During a module removal, kvm_exit invokes arch specific disable
call which disables AIA. However, we invoke aia_exit before kvm_exit
resulting in the following warning. KVM kernel module can't be inserted
afterwards due to inconsistent state of IRQ.
