This patch implements allocating alternate receive MAD buffers within the MAD stack. Support for OPA to send/recv variable sized MADs is implemented later. 1) Convert MAD allocations from kmem_cache to kzalloc kzalloc is more flexible to support devices with different sized MADs and research and testing showed that the current use of kmem_cache does not provide performance benefits over kzalloc. 2) Change struct ib_mad_private to use a flex array for the mad data 3) Allocate ib_mad_private based on the size specified by devices in rdma_max_mad_size. 4) Carry the allocated size in ib_mad_private to be used when processing ib_mad_private objects. 5) Alter DMA mappings based on the mad_size of ib_mad_private. 6) Replace the use of sizeof and static defines as appropriate 7) Add appropriate casts for the MAD data when calling processing functions.

I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have.

Fix race condition during destruction calls to avoid possibility of accessing object after it has been freed. Instead of waking up a wait queue directly, which is susceptible to a race where the object is freed between the reference count going to 0 and the wake_up(), use a completion to wait in the function doing the freeing.

Received responses are currently matched against sent requests based on TID only. According to the spec, responses should match based on the combination of TID, management class, and requester LID/GID. Without the additional qualification, an agent that is responding to two requests, both of which have the same TID, can match RMPP ACKs with the incorrect transaction. This problem can occur on the SM node when responding to SA queries.

Add support for sending and receiving large RMPP transfers. The old code supports transfers only as large as a single contiguous kernel memory allocation. This patch uses linked list of memory buffers when sending and receiving data to avoid needing contiguous pages for larger transfers. Receive side: copy the arriving MADs in chunks instead of coalescing to one large buffer in kernel space. Send side: split a multipacket MAD buffer to a list of segments, (multipacket_list) and send these using a gather list of size 2. Also, save pointer to last sent segment, and retrieve requested segments by walking list starting at last sent segment. Finally, save pointer to last-acked segment. When retrying, retrieve segments for resending relative to this pointer. When updating last ack, start at this pointer.

The MAD layer was violating the DMA API by touching data buffers used for sends after the DMA mapping was done. This causes problems on non-cache-coherent architectures, because the device doing DMA won't see updates to the payload buffers that exist only in the CPU cache. Fix this by having all MAD consumers use ib_create_send_mad() to allocate their send buffers, and moving the DMA mapping into the MAD layer so it can be done just before calling send (and after any modifications of the send buffer by the MAD layer). Tested on a non-cache-coherent PowerPC 440SPe system. Signed-off-by: NSean Hefty <sean.hefty@intel.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
