[Xen-devel] [PATCH v6 3/7] VMX: Cleanup PI per-cpu blocking list when vcpu is destroyed

[Feng Wu <feng.wu@xxxxxxxxx>]

We should remove the vCPU from the per-cpu blocking list
if it is going to be destroyed.

Signed-off-by: Feng Wu <feng.wu@xxxxxxxxx>
---
v6:
- Use vmx_pi_unblock_vcpu() instead of vmx_pi_list_remove()

v5:
- Use vmx_pi_list_remove() instead of vmx_pi_list_cleanup()

v4:
- Call vmx_pi_list_cleanup() before vmx_destroy_vmcs()
