kent: redesign api
...
This also got the dmabuf refcount hard fault issue resolved somehow.
Don't ask how or why, i'm just glad it works now.

sched: properly disable the watchdog
...
I have no idea what the FUCK the Engineers at ARM were thinking when
they decided to disable EVERY SINGLE FUCKING CPU COMPONENT on system
reset, except the FUCKING WATCHDOG. But this change will prevent the
system from randomly firing a watchdog reset.
