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>

Fix the FRV cmpxchg_local by breaking the following header dependency loop : linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h -> asm-frv/system.h -> asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h and linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h -> asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h In order to fix this : - Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they there at all anyway ? 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.

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.

All current InfiniBand devices can handle all DMA addresses, and it's hard to imagine anyone would be silly enough to build a new device that couldn't. 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.

ConnectX HCA supports shrinking WQEs, so that a single work request can be made of multiple units of wqe_shift. 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.

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.

Since the RSE synchronization will need a TIF_ flag, but all work-to-be-done bits are already used, so we have to multiplex TIF_NOTIFY_RESUME again. Signed-off-by: Shaohua Li <shaohua.li@intel.com> Signed-off-by: Petr Tesarik <ptesarik@suse.cz> Signed-off-by: Tony Luck <tony.luck@intel.com>
