* [PATCH] namespaces: utsname: use init_utsname when appropriateSerge E. Hallyn2006-10-02
| | | | | | | | | | | | | | | | | | | | | In some places, particularly drivers and __init code, the init utsns is the appropriate one to use. This patch replaces those with a the init_utsname helper. Changes: Removed several uses of init_utsname(). Hope I picked all the right ones in net/ipv4/ipconfig.c. These are now changed to utsname() (the per-process namespace utsname) in the previous patch (2/7) [akpm@osdl.org: CIFS fix] Signed-off-by: Serge E.

* RDMA: iWARP Core Changes.Tom Tucker2006-09-22
| | | | | | | | | | | | Modifications to the existing rdma header files, core files, drivers, and ulp files to support iWARP, including: - Hook iWARP CM into the build system and use it in rdma_cm. - Convert enum ib_node_type to enum rdma_node_type, which includes the possibility of RDMA_NODE_RNIC, and update everything for this.

* IB/ipath: remove stale references to userspace SMABryan O'Sullivan2006-09-22
| | | | | | | | | When we first submitted a userspace subnet management agent, it was rejected, so we left it out of the final driver submission.

* IB/ipath: simplify layering codeBryan O'Sullivan2006-09-22
| | | | | | | | | A lot of ipath layer code was only called in one place.

* IB/ipath: Performance improvements via mmap of queuesRalph Campbell2006-09-22
| | | | | | | | | | Improve performance of userspace post receive, post SRQ receive, and poll CQ operations for ipath by allowing userspace to directly mmap() receive queues and completion queues. This eliminates the copying between userspace and the kernel in the data path. Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: ipath_skip_sge() can break if num_sge > 1Ralph Campbell2006-07-24
| | | | | | | | | | | ipath_skip_sge() doesn't exactly duplicate the side effects of ipath_copy_sge() if num_sge > 1 since it doesn't decrement ss->num_sge. This could result in the sg_list being accessed out of bounds. Since ipath_skip_sge() is almost always called with num_sge == 1, the original "optimization" is almost never used.

* IB/ipath: Fix ib_ipath driver to work with SRPRalph Campbell2006-07-24
| | | | | | | | | | | I am still working on a proposal to remove the phys_to_virt() calls in the ib_ipath driver. In the mean time, this patch allows SRP to work by fixing the R_Key check and conversion from IB address to kernel virtual address. It also returns the correct page size for FMRs.

* [PATCH] IB/ipath: namespace cleanup: replace ips with ipathBryan O'Sullivan2006-07-01
| | | | | | | | | | | | | | Remove ips namespace from infinipath drivers. This renames ips_common.h to ipath_common.h. Definitions, data structures, etc. that were not used by kernel modules have moved to user-only headers. All names including ips have been renamed to ipath. Some names have had an ipath prefix added.

| | | | | | | | | | | | | These limits are somewhat artificial in that we don't actually have any device limits. However, the verbs layer expects that such limits exist and are enforced, so we make up arbitrary (but sensible) limits.
