In the Linux kernel, the following vulnerability has been resolved:

RISC-V: KVM: Teardown riscv specific bits after kvm_exit

During a module removal, kvmexit invokes arch specific disable call which disables AIA. However, we invoke aiaexit before kvm_exit resulting in the following warning. KVM kernel module can't be inserted afterwards due to inconsistent state of IRQ.

[25469.031389] percpu IRQ 31 still enabled on CPU0!

Invoke aiaexit and other arch specific cleanup functions after kvmexit so that disable gets a chance to be called first before exit.
