vt(4): Switch window when entering ddb or a panic occurs

Authored by dumbbell on Aug 24 2014, 7:27 PM.



The patch add the cngrab/cnungrab callbacks to vt(4). Their implementation is copied from syscons.

In drm_fb_helper.c, drm_fb_helper_restore_fbdev_mode() must not be executed in a taskqueue thread when DDB is active, because the thread won't run.
