Rather than introduce this separate oops_limit, how about making
panic_on_oops (and maybe all panic_on_*) take the limit value(s) instead
of being Boolean?  I think this would preserve the current behavior at
panic_on_oops = 0 and panic_on_oops = 1, but would introduce your
desired behavior at panic_on_oops = 10000.  We can make 10000 the new
default.  If a distro overrides panic_on_oops, it probably sets it to 1
like RHEL does.

Are there distros explicitly setting panic_on_oops to 0?  If so, that
could be a reason to introduce the separate oops_limit.

I'm not advocating one way or the other - I just felt this should be
explicitly mentioned and decided on.
