2022-09-28x86/cacheinfo: Add a cpu_llc_shared_mask() UP variantBorislav Petkov
On a CONFIG_SMP=n kernel, the LLC shared mask is 0, which prevents __cache_amd_cpumap_setup() from doing the L3 masks setup, and more specifically from setting up the shared_cpu_map and shared_cpu_list files in sysfs, leading to lscpu from util-linux getting confused and segfaulting. Add a cpu_llc_shared_mask() UP variant which returns a mask with a single bit set, i.e., for CPU0.

2022-09-28Revert "net: set proper memcg for net_init hooks allocations"Shakeel Butt
This reverts commit 1d0403d20f6c281cb3d14c5f1db5317caeec48e9. Anatoly Pugachev reported that the commit 1d0403d20f6c ("net: set proper memcg for net_init hooks allocations") is somehow causing the sparc64 VMs failed to boot and the VMs boot fine with that patch reverted. So, revert the patch for now and later we can debug the issue.

2022-09-28random: use expired timer rather than wq for mixing fast poolJason A. Donenfeld
Previously, the fast pool was dumped into the main pool periodically in the fast pool's hard IRQ handler. This worked fine and there weren't problems with it, until RT came around. Since RT converts spinlocks into sleeping locks, problems cropped up. Rather than switching to raw spinlocks, the RT developers preferred we make the transformation from originally doing: do_some_stuff() spin_lock() do_some_other_stuff() spin_unlock() to doing: do_some_stuff() queue_work_on(some_other_stuff_worker) This is an ordinary pattern done all over the kernel. However, Sherry noticed a 10% performance regression in qperf TCP over a 40gbps InfiniBand card. Quoting her message: > MT27500 Family [ConnectX-3] cards: > Infiniband device 'mlx4_0' port 1 status: > default gid: fe80:0000:0000:0000:0010:e000:0178:9eb1 > base lid: 0x6 > sm lid: 0x1 > state: 4: ACTIVE > phys state: 5: LinkUp > rate: 40 Gb/sec (4X QDR) > link_layer: InfiniBand > > Cards are configured with IP addresses on private subnet for IPoIB > performance testing. > Regression identified in this bug is in TCP latency in this stack as reported > by qperf tcp_lat metric: > > We have one system listen as a qperf server: > [root@yourQperfServer ~]# qperf > > Have the other system connect to qperf server as a client (in this > case, it’s X7 server with Mellanox card): > [root@yourQperfClient ~]# numactl -m0 -N0 qperf 20.20.20.101 -v -uu -ub --time 60 --wait_server 20 -oo msg_size:4K:1024K:*2 tcp_lat Rather than incur the scheduling latency from queue_work_on, we can instead switch to running on the next timer tick, on the same core. This also batches things a bit more -- once per jiffy -- which is okay now that mix_interrupt_randomness() can credit multiple bits at once.

2022-09-28random: avoid reading two cache lines on irq randomnessJason A. Donenfeld
In order to avoid reading and dirtying two cache lines on every IRQ, move the work_struct to the bottom of the fast_pool struct. add_ interrupt_randomness() always touches .pool and .count, which are currently split, because .mix pushes everything down. Instead, move .mix to the bottom, so that .pool and .count are always in the first cache line, since .mix is only accessed when the pool is full.

2022-09-28pwm: sysfs: Replace sprintf() with sysfs_emit()Andy Shevchenko
While the uses in this code are unproblematic, it's generally safer for sysfs outputs to use the new sysfs_emit() helper instead of raw calls to sprintf() and friends. This also has the benefit of annotating the uses, which makes them easier to audit and potentially use them to generate sysfs documentation from them. This patch replaces existing sprintf() calls straightforwardly with the new helper.

2022-09-28dt-bindings: mfd: qcom,spmi-pmic: Fix TM ADC node schema on PM8998Krzysztof Kozlowski
There are two bindings for Qualcomm SPMI PMIC Thermal Monitoring ADC: one for ADC HC and one for ADC TM5 and TM7. PM8998 uses the former one, so fix matching of child schema: qcom/msm8998-asus-novago-tp370ql.dtb: pmic@0: adc-tm@3400:compatible:0: 'qcom,spmi-adc-tm-hc' is not one of ['qcom,spmi-adc-tm5', 'qcom,spmi-adc-tm5-gen2', 'qcom,adc-tm7'] Fixes: 3f5117be9584 ("dt-bindings: mfd: convert to yaml Qualcomm SPMI PMIC") Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20220828084341.112146-15-krzysztof.kozlowski@linaro.org

2022-09-28dt-bindings: mfd: syscon: Require specific compatible also for simple-mfdKrzysztof Kozlowski
The syscon bindings require a device specific compatible, beside the "syscon". However schema counts "simple-mfd" as such, which allows simple-mfd+syscon to sneak in. Adjust the match to be sure simple-mfd also comes with a device specific compatible.

2022-09-28mfd: core: Delete corresponding OF node entries from list on MFD removalMichal Oleszczyk
When we consider MFD which implements hotplug (e.g. USB hotplug driver based on product and vendor IDs) functionality it turns out that its sub-devices are correctly matched with corresponding device tree nodes only at the first time. When physical device reboots or is replugged (and MFD driver is disconnected and probed back again) all sub-devices fails in mfd_add_device() with error 'Failed to locate of_node'. The reason of that behavior is that when any MFD sub-device is created for the first time (and matched with device tree node) it is added to the mfd_of_node_list. It looks like this list is never cleaned even if devices added there are intentionally removed from the system. So when MFD device is replugged and all sub-devices are matched with their device tree nodes again they fail as matched nodes already exist in mfd_of_node_list. In other words current implementation does not support MFD with hotplug feature. This commit extends MFD core for hotplugging support by removing appropriate OF node entry from mfd_of_node_list when corresponding device is removed from the system. Thanks to that when device is added once again it can be matched with its device tree node successfully.
