Hi

NEW_TLBFLUSH_CLOCK_PERIOD_SOFTIRQ is used but not registered. I've never experienced but system will panic in the very long run. I wonder why Isaku missed it.

Ouch! It doesn't cause panic, but it just becomes slow. So I missed it.

No, it will cause a null-pointer exception at do_softirq() in Xen. (*softirq_handlers[i])();

(XEN) $$$$$ PANIC in domain 0 (k6=0xf000000007c38000): ***
xen_handle_domain_access: exception table lookup failed, iip=0xf000000004043e60,
addr=0x0, spinning... [snip] (XEN) [<f000000004043e60>] do_softirq+0x120/0x1b0 (XEN) sp=f000000007c3fe00 bsp=f000000007c39390

I tried it by means of setting tlbflush_clock to huge value.

Anyway, I think it is not concerned with Anthony's problem.

Thanks, Kouya
