2020-02-11RDMA/cma: Rename cma_device ref/deref helpers to to get/putParav Pandit
Helper functions which increment/decrement reference count of the structure read better when they are named with the get/put suffix. Hence, rename cma_ref/deref_dev() to cma_dev_get/put().

2020-02-08Fix up remaining devm_ioremap_nocache() in SGI IOC3 8250 UART driverLinus Torvalds
This is a merge error on my part - the driver was merged into mainline by commit c5951e7c8ee5 ("Merge tag 'mips_5.6' of git://../mips/linux") over a week ago, but nobody apparently noticed that it didn't actually build due to still having a reference to the devm_ioremap_nocache() function, removed a few days earlier through commit 6a1000bd2703 ("Merge tag 'ioremap-5.6' of git://../ioremap"). Apparently this didn't get any build testing anywhere. Not perhaps all that surprising: it's restricted to 64-bit MIPS only, and only with the new SGI_MFD_IOC3 support enabled. I only noticed because the ioremap conflicts in the ARM SoC driver update made me check there weren't any others hiding, and I found this one.

IOW, they can be shared or kept private and if some turn out to be widely useful, we can make them common library helpers, etc., without having to do anything whatsoever to fs_parse() itself. And we already get that kind of requests - the thing that finally pushed me into doing that was "oh, and let's add one for timeouts - things like 15s or 2h".

2020-02-08net: thunderx: use proper interface type for RGMIITim Harvey
The configuration of the OCTEONTX XCV_DLL_CTL register via xcv_init_hw() is such that the RGMII RX delay is bypassed leaving the RGMII TX delay enabled in the MAC: /* Configure DLL - enable or bypass * TX no bypass, RX bypass */ cfg = readq_relaxed(xcv->reg_base + XCV_DLL_CTL); cfg &= ~0xFF03; cfg |= CLKRX_BYP; writeq_relaxed(cfg, xcv->reg_base + XCV_DLL_CTL); This would coorespond to a interface type of PHY_INTERFACE_MODE_RGMII_RXID and not PHY_INTERFACE_MODE_RGMII. Fixing this allows RGMII PHY drivers to do the right thing (enable RX delay in the PHY) instead of erroneously enabling both delays in the PHY.

2020-02-08irqchip/gic-v4.1: Ensure L2 vPE table is allocated at RD levelZenghui Yu
In GICv4, we will ensure that level2 vPE table memory is allocated for the specified vpe_id on all v4 ITS, in its_alloc_vpe_table(). This still works well for the typical GICv4.1 implementation, where the new vPE table is shared between the ITSs and the RDs. To make it explicit, let us introduce allocate_vpe_l2_table() to make sure that the L2 tables are allocated on all v4.1 RDs. We're likely not need to allocate memory in it because the vPE table is shared and (L2 table is) already allocated at ITS level, except for the case where the ITS doesn't share anything (say SVPET == 0, practically unlikely but architecturally allowed). The implementation of allocate_vpe_l2_table() is mostly copied from its_alloc_table_entry().

2020-02-08irqchip/gic-v4.1: Set vpe_l1_base for all redistributorsZenghui Yu
Currently, we will not set vpe_l1_page for the current RD if we can inherit the vPE configuration table from another RD (or ITS), which results in an inconsistency between RDs within the same CommonLPIAff group. Let's rename it to vpe_l1_base to indicate the base address of the vPE configuration table of this RD, and set it properly for *all* v4.1 redistributors.

2020-02-07mlxsw: core: Add validation of hardware device types for MGPIR registerVadim Pasternak
When reading the number of gearboxes from the hardware, the driver does not validate the returned 'device type' field. The driver can therefore wrongly assume that the queried devices are gearboxes. On Spectrum-3 systems that support different types of devices, this can prevent the driver from loading, as it will try to query the temperature sensors from devices which it assumes are gearboxes and in fact are not. For example: [ 218.129230] mlxsw_minimal 2-0048: Reg cmd access status failed (status=7(bad parameter)) [ 218.138282] mlxsw_minimal 2-0048: Reg cmd access failed (reg_id=900a(mtmp),type=write) [ 218.147131] mlxsw_minimal 2-0048: Failed to setup temp sensor number 256 [ 218.534480] mlxsw_minimal 2-0048: Fail to register core bus [ 218.540714] mlxsw_minimal: probe of 2-0048 failed with error -5 Fix this by validating the 'device type' field.

2020-02-07mlxsw: spectrum_router: Clear offload indication from IPv6 nexthops on abortIdo Schimmel
Unlike IPv4, in IPv6 there is no unique structure to represent the nexthop and both the route and nexthop information are squashed to the same structure ('struct fib6_info'). In order to improve resource utilization the driver consolidates identical nexthop groups to the same internal representation of a nexthop group. Therefore, when the offload indication of a nexthop changes, the driver needs to iterate over all the linked fib6_info and toggle their offload flag accordingly. During abort, all the routes are removed from the device and unlinked from their nexthop group. The offload indication is cleared just before the group is destroyed, but by that time no fib6_info is linked to the group and the offload indication remains set. Fix this by clearing the offload indication just before dropping the reference from the nexthop.

Stop removing modes that are not supported on the system interface when the connected PHY is capable of rate adaptation.

After this commit, the modes removed by the dpaa_eth driver were no longer advertised thus autonegotiation with 1G link partners failed.

To fix the issue, update netvsc_xdp_set() to add the correct number to refcnt. Hold a refcnt in netvsc_xdp_set()’s other caller, netvsc_attach(). And, do the same in netvsc_vf_setxdp(). Otherwise, every time when VF is removed and added from the host side, the refcnt will be decreased by one, which may cause page fault when unloading xdp program.
