Several conflicts, seemingly all over the place. I used Stephen Rothwell's sample resolutions for many of these, if not just to double check my own work, so definitely the credit largely goes to him. The NFP conflict consisted of a bug fix (moving operations past the rhashtable operation) while chaning the initial argument in the function call in the moved code. The net/dsa/master.c conflict had to do with a bug fix intermixing of making dsa_master_set_mtu() static with the fixing of the tagging attribute location. cls_flower had a conflict because the dup reject fix from Or overlapped with the addition of port range classifiction. __set_phy_supported()'s conflict was relatively easy to resolve because Andrew fixed it in both trees, so it was just a matter of taking the net-next copy. Or at least I think it was :-) Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup() intermixed with changes on how the sdif and caller_net are calculated in these code paths in net-next. The remaining BPF conflicts were largely about the addition of the __bpf_md_ptr stuff in 'net' overlapping with adjustments and additions to the relevant data structure where the MD pointer macros are used.

The CP rings are accounted differently on the new 57500 chips. There must be enough CP rings for the sum of RX and TX rings on the new chips. The current logic may be over-estimating the RX and TX rings. The output parameter max_cp should be the maximum NQs capped by MSIX vectors available for networking in the context of 57500 chips. The existing code which uses CMPL rings capped by the MSIX vectors works most of the time but is not always correct. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

The new 57500 chips have introduced the NQ structure in addition to the existing CP rings in all chips. We need to introduce a new bnxt_nq_rings_in_use(). On legacy chips, the 2 functions are the same and one will just call the other. On the new chips, they refer to the 2 separate ring structures. The new function is now called to determine the resource (NQ or CP rings) associated with MSIX that are in use. On 57500 chips, the RDMA driver does not use the CP rings so we don't need to do the subtraction adjustment. Fixes: 41e8d798 ("bnxt_en: Modify the ring reservation functions for 57500 series chips.")

Pull libnvdimm fixes from Dan Williams: "A regression fix for the Address Range Scrub implementation, yes another one, and support for platforms that misalign persistent memory relative to the Linux memory hotplug section constraint.

These have all appeared in a -next release, and thanks to Patrick for reporting and testing the alignment padding fix. Summary: - Unless and until the core mm handles memory hotplug units smaller than a section (128M), persistent memory namespaces must be padded to section alignment. The libnvdimm core already handled section collision with "System RAM", but some configurations overlap independent "Persistent Memory" ranges within a section, so additional padding injection is added for that case. - The recent reworks of the ARS (address range scrub) state machine to reduce the number of state flags inadvertantly missed a conversion of acpi_nfit_ars_rescan() call sites.

由 Andrew Lunn 提交于
It is sometimes necessary to instantiate a bit-banging MDIO bus as a platform device, without the aid of device tree. When device tree is being used, the bus is not scanned for devices, only those devices which are in device tree are probed. Without device tree, by default, all addresses on the bus are scanned. This may then find a device which is not a PHY, e.g. a switch. And the switch may have registers containing values which look like a PHY. So during the scan, a PHY device is wrongly created. After the bus has been registered, a search is made for mdio_board_info structures which indicates devices on the bus, and the driver which should be used for them. This is typically used to instantiate Ethernet switches from platform drivers. However, if the scanning of the bus has created a PHY device at the same location as indicated into the board info for a switch, the switch device is not created, since the address is already busy. This can be avoided by setting the phy_mask of the mdio bus. This mask prevents addresses on the bus being scanned. v2 Reviewed-by: NFlorian Fainelli <f.fainelli@gmail.com> Signed-off-by: NDavid S.

This reverts commit 89c83fb5. This should have been done as part of 2f0799a0 ("mm, thp: restore node-local hugepage allocations"). The movement of the thp allocation policy from alloc_pages_vma() to alloc_hugepage_direct_gfpmask() was intended to only set __GFP_THISNODE for mempolicies that are not MPOL_BIND whereas the revert could set this regardless of mempolicy. While the check for MPOL_BIND between alloc_hugepage_direct_gfpmask() and alloc_pages_vma() was racy, that has since been removed since the revert. What is left is the possibility to use __GFP_THISNODE in policy_node() when it is unexpected because the special handling for hugepages in alloc_pages_vma() was removed as part of the consolidation. Secondly, prior to 89c83fb5, alloc_pages_vma() implemented a somewhat different policy for hugepage allocations, which were allocated through alloc_hugepage_vma(). For hugepage allocations, if the allocating process's node is in the set of allowed nodes, allocate with __GFP_THISNODE for that node (for MPOL_PREFERRED, use that node with __GFP_THISNODE instead). This was changed for shmem_alloc_hugepage() to allow fallback to other nodes in 89c83fb5 as it did for new_page() in mm/mempolicy.c which is functionally different behavior and removes the requirement to only allocate hugepages locally. So this commit does a full revert of 89c83fb5 instead of the partial revert that was done in 2f0799a0. The result is the same thp allocation policy for 4.20 that was in 4.19.
