HEADS UP: Do a full buildkernel when upgrading!

[Sascha Wildner]

IMPORTANT!

Please note that after upgrading your source to or after  
0e0fd600f4c75d4dc8a6d605ba9edc960d4f205e ("kernel/kobj: Put the default  
kobj_method inside the kobjop_desc struct."), you will have to do a full  
buildkernel.

quickkernel will succeed but the kernel will not work.

Sorry for the inconvenience, but I had assumed quickkernel would not even  
compile.

Regards,
Sascha
