* [SCSI] qla2xxx: fix to honor ignored parameters in sysfs attributesSeokmann Ju2007-07-27
| | | | | | | | | | | | | | | This is a patch to fix 'segmentation fault' issue which was initiated by Richard Lary <rlary@us.ibm.com>. Thanks again Richard. - on following sysfs attritute function, changes have made so that both count and offset input parameters are honored by the functions. = qla2x00_sysfs_read_nvram() = qla2x00_sysfs_read_vpd() - made changes so that NVRAM data to be cached to minimize H/W accesses during agent querying of the driver's.

* [SCSI] iscsi_tcp: Turn off bounce buffersMike Christie2007-07-27
| | | | | | | | | | | | | It was found by LSI that on setups with large amounts of memory we were bouncing buffers when we did not need to. If the iscsi tcp code touches the data buffer (or a helper does), it will kmap the buffer. iscsi_tcp also does not interact with hardware, so it does not have any hw dma restrictions. This patch sets the bounce buffer settings for our device queue so buffers should not be bounced because of a driver limit.

* 9p: Don't use binary sysctl numbers.Eric W. Biederman2007-07-22
| | | | | | | | | | | | | | | | | | | The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that supposedly only moved files also introduced a new 9p sysctl interface that did not properly register it's sysctl binary numbers. And since it was only for debugging clearly did not need a binary fast path in any case. So this patch just remove the binary numbers. See Documentation/sysctl/ctl_unnumbered.txt for more details. While I was at it I cleaned up the sysctl initializers a little as well so there is less to read.

| * IB/ehca: Support small QP queuesStefan Roscher2007-07-21
| | | | | | | | | | | | | | | | | | | | | | eHCA2 supports QP queues that can be as small as 512 bytes. This greatly reduces memory overhead for consumers that use lots of QPs with small queues (e.g. RDMA-only QPs). Apart from dealing with firmware, this code needs to manage bite-sized chunks of kernel pages, making sure that no kernel page is shared between different protection domains.

If enabled via the mr_largepage module parameter, the MR page size will be determined based on the MR length and the hardware capabilities -- if the MR is >= 16M, 16M pages are used, for example.

| * IB/mlx4: Fix error path in create_qp_common()Roland Dreier2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | The error handling code at err_wrid in create_qp_common() does not handle a userspace QP attached to an SRQ correctly, since it ends up in the else clause of the if statement. This means it tries to kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers. Fix this so we only free the wrid arrays for kernel QPs. Pointed out by Michael S.

| * mlx4_core: Change command token on timeoutRoland Dreier2007-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The FW command token is currently only updated on a command completion event. This means that on command timeout, the same token will be reused for new command, which results in a mess if the timed out command *does* eventually complete. This is the same change as the patch for mthca from Michael S. Tsirkin <mst@dev.mellanox.co.il> that was just merged.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipath_layer.[ch] code was an attempt to provide a single interface for the ipath verbs and ipath_ether code to use. As verbs functionality increased, the layer's functionality became insufficient and the verbs code broke away to interface directly to the driver. The failed attempt to get ipath_ether upstream was the final nail in the coffin and now it sits quietly in a dark kernel.org corner waiting for someone to notice the smell and send it along to it's final resting place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, bsg doesn't make class backlinks (a process whereby you'd get a link to bsg in the device directory in the same way you get one for sg). This is because the bsg device is uninitialised, so the class device has nothing it can attach to. The fix is to make the bsg device point to the cdevice of the entity creating the bsg, necessitating changing the bsg_register_queue() prototype into a form that takes the generic device.
