The war against bugs is not lost!

Extracted from "Professional Linux Kernel Architecture" (Wolfgang Mauerer):

For comparision of the CPU quality, here is the check_bugs routine of S390, Alpha, Extensa, H8300, v850, FRV, Blackfin, Cris, PA-RISC, and PPC64:

static void check_bugs(void)

The S390 kernel is among the most confident ones, as you can see in the following code:


static inline void check_busgs(void)
  /* s390 has no bugs ... */
