2016-10-07libnvdimm, namespace: sort namespaces by dpa at initDan Williams
Add more determinism to initial namespace device-name assignments by sorting the namespaces by starting dpa. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2016-10-07libnvdimm, namespace: allow multiple pmem-namespaces per region at scan timeDan Williams
If label scanning finds multiple valid pmem namespaces allow them to be surfaced rather than fail namespace scanning. Support for creating multiple namespaces per region is saved for a later patch. Note that this adds some new error messages to clarify which of the pmem namespaces in the set are potentially impacted by invalid labels. Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2016-10-07arch/x86: Handle non enumerated CPU after physical hotplugPrarit Bhargava
When a CPU is physically added to a system then the MADT table is not updated. If subsequently a kdump kernel is started on that physically added CPU then the ACPI enumeration fails to provide the information for this CPU which is now the boot CPU of the kdump kernel. As a consequence, generic_processor_info() is not invoked for that CPU so the number of enumerated processors is 0 and none of the initializations, including the logical package id management, are performed. We have code which relies on the correctness of the logical package map and other information which is initialized via generic_processor_info(). Executing such code will result in undefined behaviour or kernel crashes. This problem applies only to the kdump kernel because a normal kexec will switch to the original boot CPU, which is enumerated in MADT, before jumping into the kexec kernel. The boot code already has a check for num_processors equal 0 in prefill_possible_map(). We can use that check as an indicator that the enumeration of the boot CPU did not happen and invoke generic_processor_info() for it. That initializes the relevant data for the boot CPU and therefore prevents subsequent failure.

2016-10-07rtl8xxxu: Fix rtl8192eu driver reload issueJes Sorensen
The 8192eu suffered from two issues when reloading the driver. The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and 23 didn't get set in rtl8192e_enable_rf(). In addition it also seems prone to issues when setting REG_RF_CTRL to 0 intead of just disabling the RF_ENABLE bit. Similar to what was causing issues with the 8188eu. With this patch I can successfully reload the driver and reassociate to an APi with an 8192eu dongle.

(2) Only ping for a lost reply in a client call (this is inapplicable to service calls). (3) Fix maybe uninitialised variable warnings in the ACK/ABORT sending function by splitting it. (4) Fix loss of PING RESPONSE ACKs due to them being subsumed by PING ACK generation. (5) OpenAFS improperly terminates calls it makes as a client under some circumstances by not fully hard-ACK'ing the last DATA packets. This is alleviated by a new call appearing on the same channel implicitly completing the previous call on that channel. Handle this implicit completion. (6) Properly handle expiry of service calls due to the aforementioned improper termination with no follow up call to implicitly complete it: (a) The call's background processor needs to be queued to complete the call, send an abort and notify the socket. (b) The call's background processor needs to notify the socket (or the kernel service) when it has completed the call. (c) A negative error code must thence be returned to the kernel service so that it knows the call died. (d) The AFS filesystem must detect the fatal error and end the call. (7) Must produce a DELAY ACK when the actual service operation takes a while to process and must cancel the ACK when the reply is ready.

2016-10-06netlink: do not enter direct reclaim from netlink_dump()Eric Dumazet
Since linux-3.15, netlink_dump() can use up to 16384 bytes skb allocations. Due to struct skb_shared_info ~320 bytes overhead, we end up using order-3 (on x86) page allocations, that might trigger direct reclaim and add stress. The intent was really to attempt a large allocation but immediately fallback to a smaller one (order-1 on x86) in case of memory stress. On recent kernels (linux-4.4), we can remove __GFP_DIRECT_RECLAIM to meet the goal. Old kernels would need to remove __GFP_WAIT While we are at it, since we do an order-3 allocation, allow to use all the allocated bytes instead of 16384 to reduce syscalls during large dumps. iproute2 already uses 32KB recvmsg() buffer sizes.

Paul Durrant says: ==================== xen-netback: guest rx side refactor This series refactors the guest rx side of xen-netback: - The code is moved into its own source module. - The prefix variant of GSO handling is retired (since it is no longer in common use, and alternatives exist). - The code is then simplified and modifications made to improve performance. v2: - Rebased onto refreshed net-next ==================== Signed-off-by: David S.

2016-10-06xen/netback: add fraglist support for to-guest rxRoss Lagerwall
This allows full 64K skbuffs (with 1500 mtu ethernet, composed of 45 fragments) to be handled by netback for to-guest rx.

2016-10-06xen-netback: batch copies for multiple to-guest rx packetsDavid Vrabel
Instead of flushing the copy ops when an packet is complete, complete packets when their copy ops are done. This improves performance by reducing the number of grant copy hypercalls. Latency is still limited by the relatively small size of the copy batch.

2016-10-06xen-netback: process guest rx packets in batchesDavid Vrabel
Instead of only placing one skb on the guest rx ring at a time, process a batch of up-to 64. This improves performance by ~10% in some tests.

2016-10-06xen-netback: refactor guest rxDavid Vrabel
Refactor the to-guest (rx) path to: 1. Push responses for completed skbs earlier, reducing latency. 2. Reduce the per-queue memory overhead by greatly reducing the maximum number of grant copy ops in each hypercall (from 4352 to 64). Each struct xenvif_queue is now only 44 kB instead of 220 kB. 3. Make the code more maintainable. Signed-off-by: David Vrabel <david.vrabel@citrix.com> [re-based] Signed-off-by: Paul Durrant <paul.durrant@citrix.com> Signed-off-by: David S.

2016-10-06xen-netback: retire guest rx side prefix GSO featurePaul Durrant
As far as I am aware only very old Windows network frontends make use of this style of passing GSO packets from backend to frontend. These frontends can easily be replaced by the freely available Xen Project Windows PV network frontend, which uses the 'default' mechanism for passing GSO packets, which is also used by all Linux frontends. NOTE: Removal of this feature will not cause breakage in old Windows frontends. They simply will no longer receive GSO packets - the packets instead being fragmented in the backend.

2016-10-06xen-netback: separate guest side rx code into separate modulePaul Durrant
The netback source module has become very large and somewhat confusing. This patch simply moves all code related to the backend to frontend (i.e guest side rx) data-path into a separate rx source module. This patch contains no functional change, it is code movement and minimal changes to avoid patch style-check issues. Signed-off-by: Paul Durrant <paul.durrant@citrix.com> Signed-off-by: David S.
