build_mlx_header() was using sqp->ud_header.grh_present before it was initialized by mthca_read_ah(). Furthermore, header->grh_present is set by ib_ud_header_init, so there's no need to set it again in mthca_read_ah(). Signed-off-by:

The current handling of multicast groups in IPoIB ends up never freeing send-only multicast groups. It turns out the logic was much more complicated than it needed to be; we can fix this bug and completely kill ipoib_mcast_dev_down() at the same time. Signed-off-by:

Multiple ipoib_neigh structures on mcast->neigh_list may point to the same ah. This means that ipoib_mcast_free() can't just make a list of ah structs to free, since this might end up trying to add the same ah to the list more than once. Handle this in ipoib_multicast.c in the same way as it is handled in ipoib_main.c for struct ipoib_path. Signed-off-by:

Add a node_guid field to struct ib_device. It is the responsibility of the low-level driver to initialize this field before registering a device with the midlayer. Convert everyone to looking at this field instead of calling ib_query_device() when all they want is the node GUID, and remove the node_guid field from struct ib_device_attr. Signed-off-by:

I am seeing EQ overruns in SDP stress tests: if the CQ completion handler arms a CQ, this could generate more EQEs, so that EQ will never get empty and consumer index will never get updated. This is similiar to what we have with command interface: /* * cmd_event() may add more commands. * The card will think the queue has overflowed if * we don't tell it we've been processing events. */ However, for completion events, we *don't* want to update the consumer index on each event. So, perform EQ doorbell coalescing: allocate EQs with some spare EQEs, and update once we run out of them. The value 0x80 was selected to avoid any performance impact. Signed-off-by:

This adds an option to remove vm86 support under CONFIG_EMBEDDED. Saves about 5k. This version eliminates most of the #ifdefs of the previous version and instead uses function stubs in vm86.h. Also, release_vm86_irqs is moved from asm-i386/irq.h to a more appropriate home in vm86.h so that the stubs can live together. $ size vmlinux-baseline vmlinux-novm86 text data bss dec hex filename 2920821 523232 190652 3634705 377611 vmlinux-baseline 2916268 523100 190492 3629860 376324 vmlinux-novm86 Signed-off-by:

Use first_cpu(cpu_possible_map) for the single-thread workqueue case. We used to hardcode 0, but that broke on systems where !cpu_possible(0) when workqueue_struct->cpu_workqueue_struct was changed from a static array to alloc_percpu. Commit id bce61dd4 ("Fix hardcoded cpu=0 in workqueue for per_cpu_ptr() calls") fixed that for Ben's funky sparc64 system, but it regressed my Power5. Offlining cpu 0 oopses upon the next call to queue_work for a single-thread workqueue, because now we try to manipulate per_cpu_ptr(wq->cpu_wq, 1), which is uninitialized. So we need to establish an unchanging "slot" for single-thread workqueues which will have a valid percpu allocation. Since alloc_percpu keys off of cpu_possible_map, which must not change after initialization, make this slot == first_cpu(cpu_possible_map). Signed-off-by:

Since version 4.1 the gcc is warning about ignored attributes. This patch is using the equivalent attribute on the struct instead of on each of the structure or union members. GCC Manual: "Specifying Attributes of Types packed This attribute, attached to struct or union type definition, specifies that each member of the structure or union is placed to minimize the memory required. When attached to an enum definition, it indicates that the smallest integral type should be used. Specifying this attribute for struct and union types is equivalent to specifying the packed attribute on each of the structure or union members." Signed-off-by: -
