2020-10-07x86/platform/uv: Update UV MMRs for UV5Mike Travis
Update UV MMRs in uv_mmrs.h for UV5 based on Verilog output from the UV Hub hardware design files. This is the next UV architecture with a new class (UVY) being defined for 52 bit physical address masks. Uses a bitmask for UV arch identification so a single test can cover multiple versions. Includes other adjustments to match the uv_mmrs.h file to keep from encountering compile errors. New UV5 functionality is added in the patches that follow.

2020-09-26mm: don't rely on system state to detect hot-plug operationsLaurent Dufour
In register_mem_sect_under_node() the system_state's value is checked to detect whether the call is made during boot time or during an hot-plug operation. Unfortunately, that check against SYSTEM_BOOTING is wrong because regular memory is registered at SYSTEM_SCHEDULING state. In addition, memory hot-plug operation can be triggered at this system state by the ACPI [1]. So checking against the system state is not enough. The consequence is that on system with interleaved node's ranges like this: Early memory node ranges node 1: [mem 0x0000000000000000-0x000000011fffffff] node 2: [mem 0x0000000120000000-0x000000014fffffff] node 1: [mem 0x0000000150000000-0x00000001ffffffff] node 0: [mem 0x0000000200000000-0x000000048fffffff] node 2: [mem 0x0000000490000000-0x00000007ffffffff] This can be seen on PowerPC LPAR after multiple memory hot-plug and hot-unplug operations are done. At the next reboot the node's memory ranges can be interleaved and since the call to link_mem_sections() is made in topology_init() while the system is in the SYSTEM_SCHEDULING state, the node's id is not checked, and the sections registered to multiple nodes: $ ls -l /sys/devices/system/memory/memory21/node* total 0 lrwxrwxrwx 1 root root 0 Aug 24 05:27 node1 -> ../../node/node1 lrwxrwxrwx 1 root root 0 Aug 24 05:27 node2 -> ../../node/node2 In that case, the system is able to boot but if later one of theses memory blocks is hot-unplugged and then hot-plugged, the sysfs inconsistency is detected and this is triggering a BUG_ON(): kernel BUG at /Users/laurent/src/linux-ppc/mm/memory_hotplug.c:1084!

An extra parameter is added to link_mem_sections() detailing whether the operation is due to a hot-plug operation. [1] According to Oscar Salvador, using this qemu command line, ACPI memory hotplug operations are raised at SYSTEM_SCHEDULING state: $QEMU -enable-kvm -machine pc -smp 4,sockets=4,cores=1,threads=1 -cpu host -monitor pty \ -m size=$MEM,slots=255,maxmem=4294967296k \ -numa node,nodeid=0,cpus=0-3,mem=512 -numa node,nodeid=1,mem=512 \ -object memory-backend-ram,id=memdimm0,size=134217728 -device pc-dimm,node=0,memdev=memdimm0,id=dimm0,slot=0 \ -object memory-backend-ram,id=memdimm1,size=134217728 -device pc-dimm,node=0,memdev=memdimm1,id=dimm1,slot=1 \ -object memory-backend-ram,id=memdimm2,size=134217728 -device pc-dimm,node=0,memdev=memdimm2,id=dimm2,slot=2 \ -object memory-backend-ram,id=memdimm3,size=134217728 -device pc-dimm,node=0,memdev=memdimm3,id=dimm3,slot=3 \ -object memory-backend-ram,id=memdimm4,size=134217728 -device pc-dimm,node=1,memdev=memdimm4,id=dimm4,slot=4 \ -object memory-backend-ram,id=memdimm5,size=134217728 -device pc-dimm,node=1,memdev=memdimm5,id=dimm5,slot=5 \ -object memory-backend-ram,id=memdimm6,size=134217728 -device pc-dimm,node=1,memdev=memdimm6,id=dimm6,slot=6 \ Fixes: 4fbce633910e ("mm/memory_hotplug.c: make register_mem_sect_under_node() a callback of walk_memory_range()") Signed-off-by: Laurent Dufour <ldufour@linux.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: David Hildenbrand <david@redhat.com> Reviewed-by: Oscar Salvador <osalvador@suse.de> Acked-by: Michal Hocko <mhocko@suse.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: "Rafael J.

The commit 1098582a0f6c ("sched,idle,rcu: Push rcu_idle deeper into the idle path"), moved the calls rcu_idle_enter|exit() into the cpuidle core. However, it forgot to remove a couple of comments in enter_s2idle_proper() about why RCU_NONIDLE earlier was needed. So, let's drop them as they have become a bit misleading.

2020-09-22nvme-fc: fail new connections to a deleted host or remote portJames Smart
The lldd may have made calls to delete a remote port or local port and the delete is in progress when the cli then attempts to create a new controller. Currently, this proceeds without error although it can't be very successful. Fix this by validating that both the host port and remote port are present when a new controller is to be created.

2020-09-22nvme-pci: fix NULL req in completion handlerXianting Tian
Currently, we use nvmeq->q_depth as the upper limit for a valid tag in nvme_handle_cqe(), it is not correct. Because the available tag number is recorded in tagset, which is not equal to nvmeq->q_depth. The nvme driver registers interrupts for queues before initializing the tagset, because it uses the number of successful request_irq() calls to configure the tagset parameters. This allows a race condition with the current tag validity check if the controller happens to produce an interrupt with a corrupted CQE before the tagset is initialized. Replace the driver's indirect tag check with the one already provided by the block layer.

The set of TLS TX global SW counters in mlx5e_tls_sw_stats_desc is updated from all rings by using atomic ops. This set of stats is used only in the FPGA TLS use case, not in the Connect-X TLS one, where regular per-ring counters are used. Do not expose them in the Connect-X use case, as this would cause counter duplication. For example, tx_tls_drop_no_sync_data would appear twice in the ethtool stats.

The cited commit started to reuse function mlx5e_update_ndo_stats() for the representors as well. However, the function is hard-coded to work on mlx5e_nic_stats_grps only. Due to this issue, the representors statistics were not updated in the output of "ip -s". Fix it to work with the correct group by extracting it from the caller's profile. Also, while at it and since this function became generic, move it to en_stats.c and rename it accordingly.

2020-09-21net/mlx5e: Fix multicast counter not up-to-date in "ip -s"Ron Diskin
Currently the FW does not generate events for counters other than error counters. Unlike ".get_ethtool_stats", ".ndo_get_stats64" (which ip -s uses) might run in atomic context, while the FW interface is non atomic. Thus, 'ip' is not allowed to issue FW commands, so it will only display cached counters in the driver. Add a SW counter (mcast_packets) in the driver to count rx multicast packets. The counter also counts broadcast packets, as we consider it a special case of multicast. Use the counter value when calling "ip -s"/"ifconfig".
