2016-11-09PCI/MSI: Provide pci_alloc_irq_vectors_affinity()Christoph Hellwig
This is a variant of pci_alloc_irq_vectors() that allows passing a struct irq_affinity to provide fine-grained IRQ affinity control. For now this means being able to exclude vectors at the beginning or end of the MSI vector space, but it could also be used for any other quirks needed in the future (e.g. more vectors than CPUs, or excluding CPUs from the spreading).

2016-11-09genirq/affinity: Introduce struct irq_affinityChristoph Hellwig
Some drivers (various network and RDMA adapter for example) have a MSI-X vector layout where most of the vectors are used for I/O queues and should have CPU affinity assigned to them, but some (usually 1 but sometimes more) at the beginning or end are used for low-performance admin or configuration work and should not have any explicit affinity assigned to them. Add a new irq_affinity structure, which will be passed through a variant of pci_irq_alloc_vectors that allows to specify these requirements (and is extensible to any future quirks in that area) so that the core IRQ affinity algorithm can take this quirks into account.

When a sequence times out we have no idea what happened to the frame. And we do not know if we will ever receive the frame. Hence we cannot re-use the xid as we would risk data corruption if the xid had been re-used and the timed out frame would be received after that. So we need to quarantine the xid until the lport is reset. Yes, I know this will (eventually) deplete the xid pool. But for now it's the safest method.

2016-11-08percpu: use notrace variant of preempt_disable/preempt_enableHeiko Carstens
Commit 345ddcc882d8 ("ftrace: Have set_ftrace_pid use the bitmap like events do") added a couple of this_cpu_read calls to the ftrace code. On x86 this is not a problem, since it has single instructions to read percpu data. Other architectures which use the generic variant now have additional preempt_disable and preempt_enable calls in the core ftrace code. This may lead to recursive calls and in result to a dead machine, e.g. if preemption and debugging options are enabled. To fix this use the notrace variant of preempt_disable and preempt_enable within the generic percpu code.
