Drivers: hv: restore hypervcall page cleanup before kexec
We need to cleanup the hypercall page before doing kexec/kdump or the new kernel may crash if it tries to use it. Reuse the now-empty hv_cleanup function renaming it to hyperv_cleanup and moving to the arch specific code. Fixes: 8730046c1498 ("Drivers: hv vmbus: Move Hypercall page setup out of common code") Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y.
