The current implementation allocates a single host page for EQ context memory, which was OK when we only allocated a few EQs. However, since we now allocate an EQ for each CPU core, this patch removes the hard-coded limit (which we exceed with 4 KB pages and 128 byte EQ context entries with 32 CPUs) and uses the same ICM table code as all other context tables, which ends up simplifying the code quite a bit while fixing the problem. This problem was actually hit in practice on a dual-socket Nehalem box with 16 real hardware threads and sufficiently odd ACPI tables that it shows on boot SMP: Allowing 32 CPUs, 16 hotplug CPUs so num_possible_cpus() ends up 32, and mlx4 ends up creating 33 MSI-X interrupts and 33 EQs. This mlx4 bug means that mlx4 can't even initialize at all on this quite mainstream system.

The use of "A functions set" in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use "B functions set" to prevent the irqs from getting enabled while in netpoll_send_skb(). A functions set: local_irq_disable()/local_irq_enable() spin_lock_irq()/spin_unlock_irq() spin_trylock_irq()/spin_unlock_irq() B functions set: local_irq_save()/local_irq_restore() spin_lock_irqsave()/spin_unlock_irqrestore() spin_trylock_irqsave()/spin_unlock_irqrestore() Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com> Acked-by: Matt Mackall <mpm@selenic.com> Signed-off-by: David S.
