A bug causes an oops. Oops are counted. So, why do we need this
additional complexity when we already have the '#' counter in oops
dumps?
For instance, on ARM:
Unable to handle kernel NULL pointer dereference at virtual address 00000090
pgd = c0004000
[00000090] *pgd=00000000
Internal error: Oops: 817 [#1]
^^^^
This is the oops counter. Anything oops report from anyone other than the
first should always be questioned. Also note that this counter is not
re-settable at run time, unlike the taint flags.
