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

system from randomly firing a watchdog reset.

Make memcmp more compiler friendly

The Thumb ISA allows incrementing a pointer right after dereferencing
it. This commit attempts to make it more obvious to the compiler to use
this instruction in memcmp().
