It's also important to notice that since we have adopted the use of the pseudo-keyword macro fallthrough, we also want to avoid having more /* fall through */ comments being introduced. Contrary to GCC, Clang doesn't recognize any comments as implicit fall-through markings when the -Wimplicit-fallthrough option is enabled. So, in order to avoid having more comments being introduced, we use the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang, will cause a warning in case a code comment is intended to be used as a fall-through marking. The patch for Makefile also enforces this. We had almost 4,000 of these issues for Clang in the beginning, and there might be a couple more out there when building some architectures with certain configurations. However, with the recent fixes I think we are in good shape and it is now possible to enable the warning for Clang" * tag 'Wimplicit-fallthrough-clang-5.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux: (27 commits) Makefile: Enable -Wimplicit-fallthrough for Clang powerpc/smp: Fix fall-through warning for Clang dmaengine: mpc512x: Fix fall-through warning for Clang usb: gadget: fsl_qe_udc: Fix fall-through warning for Clang powerpc/powernv: Fix fall-through warning for Clang MIPS: Fix unreachable code issue MIPS: Fix fall-through warnings for Clang ASoC: Mediatek: MT8183: Fix fall-through warning for Clang power: supply: Fix fall-through warnings for Clang dmaengine: ti: k3-udma: Fix fall-through warning for Clang s390: Fix fall-through warnings for Clang dmaengine: ipu: Fix fall-through warning for Clang iommu/arm-smmu-v3: Fix fall-through warning for Clang mmc: jz4740: Fix fall-through warning for Clang PCI: Fix fall-through warning for Clang scsi: libsas: Fix fall-through warning for Clang video: fbdev: Fix fall-through warning for Clang math-emu: Fix fall-through warning cpufreq: Fix fall-through warning for Clang drm/msm: Fix fall-through warning in msm_gem_new_impl() ...

2021-07-15xen-blkfront: sanitize the removal state machineChristoph Hellwig
xen-blkfront has a weird protocol where close message from the remote side can be delayed, and where hot removals are treated somewhat differently from regular removals, all leading to potential NULL pointer removals, and a del_gendisk from the block device release method, which will deadlock. Fix this by just performing normal hot removals even when the device is opened like all other Linux block drivers.

2021-07-14drm/i915/gtt: drop the page table optimisationMatthew Auld
We skip filling out the pt with scratch entries if the va range covers the entire pt, since we later have to fill it with the PTEs for the object pages anyway. However this might leave open a small window where the PTEs don't point to anything valid for the HW to consume. When for example using 2M GTT pages this fill_px() showed up as being quite significant in perf measurements, and ends up being completely wasted since we ignore the pt and just use the pde directly. Anyway, currently we have our PTE construction split between alloc and insert, which is probably slightly iffy nowadays, since the alloc doesn't actually allocate anything anymore, instead it just sets up the page directories and points the PTEs at the scratch page. Later when we do the insert step we re-program the PTEs again. Better might be to squash the alloc and insert into a single step, then bringing back this optimisation(along with some others) should be possible.

2021-07-14iommu/vt-d: Global devTLB flush when present context entry changedSanjay Kumar
This fixes a bug in context cache clear operation. The code was not following the correct invalidation flow. A global device TLB invalidation should be added after the IOTLB invalidation. At the same time, it uses the domain ID from the context entry. But in scalable mode, the domain ID is in PASID table entry, not context entry.

2021-07-14iommu/qcom: Revert "iommu/arm: Cleanup resources in case of probe error path"Marek Szyprowski
QCOM IOMMU driver calls bus_set_iommu() for every IOMMU device controller, what fails for the second and latter IOMMU devices. This is intended and must be not fatal to the driver registration process. Also the cleanup path should take care of the runtime PM state, what is missing in the current patch. Revert relevant changes to the QCOM IOMMU driver until a proper fix is prepared. This partially reverts commit 249c9dc6aa0db74a0f7908efd04acf774e19b155.

2021-07-13drm/i915/gt: Fix -EDEADLK handling regressionVille Syrjälä
The conversion to ww mutexes failed to address the fence code which already returns -EDEADLK when we run out of fences. Ww mutexes on the other hand treat -EDEADLK as an internal errno value indicating a need to restart the operation due to a deadlock. So now when the fence code returns -EDEADLK the higher level code erroneously restarts everything instead of returning the error to userspace as is expected. To remedy this let's switch the fence code to use a different errno value for this. -ENOBUFS seems like a semi-reasonable unique choice. Apart from igt the only user of this I could find is sna, and even there all we do is dump the current fence registers from debugfs into the X server log. So no user visible functionality is affected. If we really cared about preserving this we could of course convert back to -EDEADLK higher up, but doesn't seem like that's worth the hassle here. Not quite sure which commit specifically broke this, but I'll just attribute it to the general gem ww mutex work.

2021-07-13sfc: ensure correct number of XDP queuesÍñigo Huguet
Commit 99ba0ea616aa ("sfc: adjust efx->xdp_tx_queue_count with the real number of initialized queues") intended to fix a problem caused by a round up when calculating the number of XDP channels and queues. However, this was not the real problem. The real problem was that the number of XDP TX queues had been reduced to half in commit e26ca4b53582 ("sfc: reduce the number of requested xdp ev queues"), but the variable xdp_tx_queue_count had remained the same. Once the correct number of XDP TX queues is created again in the previous patch of this series, this also can be reverted since the error doesn't actually exist. Only in the case that there is a bug in the code we can have different values in xdp_queue_number and efx->xdp_tx_queue_count. Because of this, and per Edward Cree's suggestion, I add instead a WARN_ON to catch if it happens again in the future. Note that the number of allocated queues can be higher than the number of used ones due to the round up, as explained in the existing comment in the code. That's why we also have to stop increasing xdp_queue_number beyond efx->xdp_tx_queue_count. Signed-off-by: Íñigo Huguet <ihuguet@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-07-13sfc: fix lack of XDP TX queues - error XDP TX failed (-22)Íñigo Huguet
Fixes: e26ca4b53582 sfc: reduce the number of requested xdp ev queues The buggy commit intended to allocate less channels for XDP in order to be more unlikely to reach the limit of 32 channels of the driver. The idea was to use each IRQ/eventqeue for more XDP TX queues than before, calculating which is the maximum number of TX queues that one event queue can handle. For example, in EF10 each event queue could handle up to 8 queues, better than the 4 they were handling before the change. This way, it would have to allocate half of channels than before for XDP TX. The problem is that the TX queues are also contained inside the channel structs, and there are only 4 queues per channel. Reducing the number of channels means also reducing the number of queues, resulting in not having the desired number of 1 queue per CPU. This leads to getting errors on XDP_TX and XDP_REDIRECT if they're executed from a high numbered CPU, because there only exist queues for the low half of CPUs, actually. If XDP_TX/REDIRECT is executed in a low numbered CPU, the error doesn't happen. This is the error in the logs (repeated many times, even rate limited): sfc 0000:5e:00.0 ens3f0np0: XDP TX failed (-22) This errors happens in function efx_xdp_tx_buffers, where it expects to have a dedicated XDP TX queue per CPU. Reverting the change makes again more likely to reach the limit of 32 channels in machines with many CPUs. If this happen, no XDP_TX/REDIRECT will be possible at all, and we will have this log error messages: At interface probe: sfc 0000:5e:00.0: Insufficient resources for 12 XDP event queues (24 other channels, max 32) At every subsequent XDP_TX/REDIRECT failure, rate limited: sfc 0000:5e:00.0 ens3f0np0: XDP TX failed (-22) However, without reverting the change, it makes the user to think that everything is OK at probe time, but later it fails in an unpredictable way, depending on the CPU that handles the packet. It is better to restore the predictable behaviour. If the user sees the error message at probe time, he/she can try to configure the best way it fits his/her needs. At least, he/she will have 2 options: - Accept that XDP_TX/REDIRECT is not available (he/she may not need it) - Load sfc module with modparam 'rss_cpus' with a lower number, thus creating less normal RX queues/channels, letting more free resources for XDP, with some performance penalty. Anyway, let the calculation of maximum TX queues that can be handled by a single event queue, and use it only if it's less than the number of TX queues per channel. This doesn't happen in practice, but could happen if some constant values are tweaked in the future, such us EFX_MAX_TXQ_PER_CHANNEL, EFX_MAX_EVQ_SIZE or EFX_MAX_DMAQ_SIZE.

2021-07-13net: dsa: sja1105: fix address learning getting disabled on the CPU portVladimir Oltean
In May 2019 when commit 640f763f98c2 ("net: dsa: sja1105: Add support for Spanning Tree Protocol") was introduced, the comment that "STP does not get called for the CPU port" was true. This changed after commit 0394a63acfe2 ("net: dsa: enable and disable all ports") in August 2019 and went largely unnoticed, because the sja1105_bridge_stp_state_set() method did nothing different compared to the static setup done by sja1105_init_mac_settings(). With the ability to turn address learning off introduced by the blamed commit, there is a new priv->learn_ena port mask in the driver. When sja1105_bridge_stp_state_set() gets called and we are in BR_STATE_LEARNING or later, address learning is enabled or not depending on priv->learn_ena & BIT(port). So what happens is that priv->learn_ena is not being set from anywhere for the CPU port, and the static configuration done by sja1105_init_mac_settings() is being overwritten. To solve this, acknowledge that the static configuration of STP state is no longer necessary because the STP state is being set by the DSA core now, but what is necessary is to set priv->learn_ena for the CPU port.
