2020-02-13RDMA/hns: Delayed flush cqe process with workqueueYixian Liu
HiP08 RoCE hardware lacks ability(a known hardware problem) to flush outstanding WQEs if QP state gets into errored mode for some reason. To overcome this hardware problem and as a workaround, when QP is detected to be in errored state during various legs like post send, post receive etc[1], flush needs to be performed from the driver. The earlier patch[1] sent to solve the hardware limitation explained in the cover-letter had a bug in the software flushing leg. It acquired mutex while modifying QP state to errored state and while conveying it to the hardware using the mailbox. This caused leg to sleep while holding spin-lock and caused crash. Suggested Solution: we have proposed to defer the flushing of the QP in the Errored state using the workqueue to get around with the limitation of our hardware. This patch specifically adds the calls to the flush handler from where parts of the code like post_send/post_recv etc. when the QP state gets into the errored mode.

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.

The system-wide registry of syntax types (string/enum/int32/oct32/.../etc.) is gone and so is the horror switch() in fs_parse() that would have to grow another case every time something got added to that system-wide registry. New syntax types can be added by filesystems easily now, and their namespace is that of functions - not of system-wide enum members. 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". If some filesystem really wants that, let them do it. Without somebody having to play gatekeeper for the variants blessed by direct support in fs_parse(), TYVM. Quite a bit of boilerplate is gone.

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().

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.
