Nit:  For the patch Subject, capitalize "Drivers:" in the prefix.

> vmbus_interrupt is used in mshv_vtl_main.c to set the SINT vector.
> When CONFIG_MSHV_VTL=m and CONFIG_HYPERV_VMBUS=y (built-in), the module
> cannot access vmbus_interrupt at load time since it is not exported.
> 
> Export it using EXPORT_SYMBOL_FOR_MODULES consistent with the existing
> pattern used for vmbus_isr.
