Following patch reworks car_disable into C. Tested, works here. I compared
also the GCC generated code and it looks all right. Please test on some
multicore CPU.
I added the "memory" clobber to read_cr0 / write_cr0 function as it is in Linux
Kernel. Seems that if this is missing, GCC is too smart and messes the order
of reads/writes to CR0 (not tested if really a problem here, but be safe for
future users of this function ;)
