NVME Initiator: Base modifications This patch adds base modifications for NVME initiator support. The base modifications consist of: - Formal split of SLI3 rings from SLI-4 WQs (sometimes referred to as rings as well) as implementation now widely varies between the two. - Addition of configuration modes: SCSI initiator only; NVME initiator only; NVME target only; and SCSI and NVME initiator. The configuration mode drives overall adapter configuration, offloads enabled, and resource splits. NVME support is only available on SLI-4 devices and newer fw. - Implements the following based on configuration mode: - Exchange resources are split by protocol; Obviously, if only 1 mode, then no split occurs. Default is 50/50. module attribute allows tuning. - Pools and config parameters are separated per-protocol - Each protocol has it's own set of queues, but share interrupt vectors. SCSI: SLI3 devices have few queues and the original style of queue allocation remains. SLI4 devices piggy back on an "io-channel" concept that eventually needs to merge with scsi-mq/blk-mq support (it is underway). For now, the paradigm continues as it existed prior. io channel allocates N msix and N WQs (N=4 default) and either round robins or uses cpu # modulo N for scheduling. A bunch of module parameters allow the configuration to be tuned. NVME (initiator): Allocates an msix per cpu (or whatever pci_alloc_irq_vectors gets) Allocates a WQ per cpu, and maps the WQs to msix on a WQ # modulo msix vector count basis. Module parameters exist to cap/control the config if desired. - Each protocol has its own buffer and dma pools. I apologize for the size of the patch. Signed-off-by:

When we have turned off RTC support, the smartpqi driver fails to build: ERROR: "rtc_time64_to_tm" [drivers/scsi/smartpqi/smartpqi.ko] undefined! This is easily avoided by using the generic 'struct tm' based helper rather than the RTC specific one. While fixing this, I noticed that even though the driver uses time64_t for storing seconds, it gets them from the old 32-bit struct timeval. To address this, we can simplify the code by calling ktime_get_real_seconds() directly. Fixes: 6c223761 ("smartpqi: initial commit of Microsemi smartpqi driver") Signed-off-by:

Currently driver checks the health status of the adapter once every 24 hours. When that happens the driver becomes dependent on the kernel to figure out if the adapter is misbehaving. This might take some time (when the adapter is idle). The driver currently has support to restart/recover the controller when it fails, and decreasing the time interval will help. Fixed by decreasing check interval from 24 hours to 1 minute Signed-off-by:

aac_command_thread checks on the health of controller periodically, using aac_check_health. If the status is an error state KERNEL_PANIC or anything else. The driver will attempt to restart the adapter, but the response is not checked in aac_command_thread. This allows the periodic sync to go thru and lead the driver to a hung state.

This allows the hash table to be sized based on the current memory usage of the guest, rather than the maximum possible memory usage. - Implementation of optprobes (kprobe optimisation) for powerpc.

Pull networking updates from David Miller: "Highlights: 1) Support TX_RING in AF_PACKET TPACKET_V3 mode, from Sowmini Varadhan. 2) Simplify classifier state on sk_buff in order to shrink it a bit. From Willem de Bruijn. 3) Introduce SIPHASH and it's usage for secure sequence numbers and syncookies. From Jason A. Donenfeld. 4) Reduce CPU usage for ICMP replies we are going to limit or suppress, from Jesper Dangaard Brouer. 5) Introduce Shared Memory Communications socket layer, from Ursula Braun. 6) Add RACK loss detection and allow it to actually trigger fast recovery instead of just assisting after other algorithms have triggered it. From Yuchung Cheng. 7) Add xmit_more and BQL support to mvneta driver, from Simon Guinot. 8) skb_cow_data avoidance in esp4 and esp6, from Steffen Klassert. 9) Export MPLS packet stats via netlink, from Robert Shearman. 10) Significantly improve inet port bind conflict handling, especially when an application is restarted and changes it's setting of reuseport. From Josef Bacik. 11) Implement TX batching in vhost_net, from Jason Wang. 12) Extend the dummy device so that VF (virtual function) features, such as configuration, can be more easily tested.
