* Replace {un}register_cpu_notifier with {un}register_hotcpu_notifier thereby losing a couple of #ifdef HOTPLUG_CPU pairs. * Move comp_pool_callback_nb declaration to below that of callback function so that initialization of .notifier_call and .priority can occur at build time itself and not runtime. * Mark the notifier_block (and callback function, and another static function used by it) as __cpuinit{data} for the sake of consistency and remove enclosing #ifdef. (This may increase size for modular build of this module, however, because these are no longer dropped unconditionally now.) Signed-off-by:Satyam Sharma <satyam@infradead.org> Acked-by:

The SRC ("scalable RC") transport has been renamed to XRC ("extended RC"), to avoid having an abbreviation that is so easily confused with an abbreviation for "source." Update the HCA capability decoding output to use the new name. Signed-off-by: -

<asm/scatterlist.h> is not needed because everyplace it appears, <linux/scatterlist.h> also appears. <asm/io.h> is not needed because nothing seems to be using device IO anyway. Signed-off-by: -

Calling arp_send() to initiate neighbour discovery (ND) doesn't do the full ND protocol. Namely, it doesn't handle retransmitting the arp request if it is dropped. The function neigh_event_send() does all this. Without doing full ND, RDMA address resolution fails in the presence of dropped ARP broadcast packets. Signed-off-by:

During ib_umem_get(), determine whether all pages from the memory region are hugetlb pages and report this in the "hugetlb" member. Low-level drivers can use this information if they need it. Signed-off-by:

Provide support to specify a type of service for a communication identifier. A new function call is used when dealing with IPv4 addresses. For IPv6 addresses, the ToS is specified through the traffic class field in the sockaddr_in6 structure. Signed-off-by:

We can use raw_smp_processor_id() here because the processor ID is only used for debug output and therefore our use is preemption-unsafe. Signed-off-by:

Use Paul's new remap_4k_pfn() function to map our 4K firmware contexts into user space on 64K-page machines without exposing neighboring firmware contexts. Return the context's offset within a 64K page to user space so it can determine the proper virtual address. For details about remap_4k_pfn(), see commit 721151d0 or http://patchwork.ozlabs.org/linuxppc/patch?id=10281Signed-off-by:

These driver changes incorporate the proposed PCI-X / PCI-Express read byte count interface. Reading and setting those values doesn't take place "manually", instead wrapping functions are called to allow quirks for some PCI bridges.

Recover from MSI-X errors by automatically falling back on regular interrupt, instead of asking the user to do this manually. This makes it possible to enable MSI-X by default, and will make it possible to get rid of the msi_x module option in the future. Signed-off-by:

The current IPoIB code might process receive completions from ipoib_drain_cq() when bringing down the interface. This could cause packets to be passed up the stack without the device's poll method being called. Avoid this by setting the status of any successful completions to IB_WC_WR_FLUSH_ERR.
