* mm: special mapping nopageNick Piggin2008-02-081-9/+16
| | | | | | | | | | | | | | | | | | | | Convert special mapping install from nopage to fault. Because the "vm_file" is NULL for the special mapping, the generic VM code has messed up "vm_pgoff" thinking that it's an anonymous mapping and the offset does't matter. For that reason, we need to undo the vm_pgoff offset that got added into vmf->pgoff. [ We _really_ should clean that up - either by making this whole special mapping code just use a real file entry rather than that ugly array of "struct page" pointers, or by just making the VM code realize that even if vm_file is NULL it may not be a regular anonymous mmap. - Linus ] Signed-off-by: Nick Piggin <npiggin@suse.de> Cc: linux-mm@kvack.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * [IA64] Fix large MCA bootmem allocationRuss Anderson2008-02-081-29/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The MCA code allocates bootmem memory for NR_CPUS, regardless of how many cpus the system actually has. This change allocates memory only for cpus that actually exist. On my test system with NR_CPUS = 1024, reserved memory was reduced by 130944k.

| * [IA64] Synchronize kernel RSE to user-space and backPetr Tesarik2008-02-084-0/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is base kernel patch for ptrace RSE bug. It's basically a backport from the utrace RSE patch I sent out several weeks ago. please review. when a thread is stopped (ptraced), debugger might change thread's user stack (change memory directly), and we must avoid the RSE stored in kernel to override user stack (user space's RSE is newer than kernel's in the case). To workaround the issue, we copy kernel RSE to user RSE before the task is stopped, so user RSE has updated data. we then copy user RSE to kernel after the task is resummed from traced stop and kernel will use the newer RSE to return to user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch acts as a preparation for using checksum offload for IB devices capable of inserting/verifying checksum in IP packets. The patch does not actaully turn on NETIF_F_SG - we defer that to the patches adding checksum offload capabilities. We only add support for send gathers for datagram mode, since existing HW does not support checksum offload on connected QPs. Signed-off-by: Michael S.

Therefore, enable the NETIF_F_HIGHDMA feature for IPoIB. This has no effect for no, but is needed when we enable gather/scatter support and checksum stateless offloads.

| * | IB/mlx4: Use multiple WQ blocks to post smaller send WQEsJack Morgenstein2008-02-085-36/+197

This way, WRs can differ in size, and do not have to be a power of 2 in size, saving memory and speeding up send WR posting. Unfortunately, if we do this then the wqe_index field in CQEs can't be used to look up the WR ID anymore, so our implementation does this only if selective signaling is off. Further, on 32-bit platforms, we can't use vmap() to make the QP buffer virtually contigious. Thus we have to use constant-sized WRs to make sure a WR is always fully within a single page-sized chunk. Finally, we use WRs with the NOP opcode to avoid wrapping around the queue buffer in the middle of posting a WR, and we set the NoErrorCompletion bit to avoid getting completions with error for NOP WRs. However, NEC is only supported starting with firmware 2.2.232, so we use constant-sized WRs for older firmware. And, since MLX QPs only support SEND, we use constant-sized WRs in this case. When stamping during NOP posting, do stamping following setting of the NOP WQE valid bit. Signed-off-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that struct mlx4_buf.u is a struct instead of a union because of the vmap() changes, there's no point in having a struct at all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since kernel virtual memory is not a problem on 64-bit systems, there is no reason to use our own 2-layer page mapping scheme for large kernel queue buffers on such systems. Instead, map the page list to a single virtually contiguous buffer with vmap(), so that can we access buffer memory via direct indexing. Signed-off-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use struct mlx4_buf for kernel QP, CQ and SRQ buffers, and the code to look up an entry is duplicated in get_cqe_from_buf() and the QP and SRQ versions of get_wqe(). Factor this out into mlx4_buf_offset(). This will also make it easier to switch over to using vmap() for buffers. Signed-off-by: Roland Dreier <rolandd@cisco.com>

They are not touching atomic_t variables!) to asm-frv/bitops.h. Also fix a build issue with cmpxchg : it does not cast to (unsigned long *) like other architectures, to deal with it in the cmpxchg_local macro. FRV builds fine with this patch. Thanks to Adrian Bunk <bunk@kernel.org> for spotting this bug.
