2022-03-17cpufreq: powernow-k8: Re-order the init checksMario Limonciello

Because of this the following warning comes up on systems that support amd-pstate and compiled in both drivers: `WTF driver: amd-pstate` The systems that support powernow-k8 will not support amd-pstate, so re-order the checks to validate the CPU model number first to avoid this warning being displayed on modern SOCs.

2022-03-17ACPI: bus: Avoid using CPPC if not supported by firmwareRafael J. Wysocki
If the platform firmware indicates that it does not support CPPC by clearing the OSC_SB_CPC_SUPPORT and OSC_SB_CPCV2_SUPPORT bits in the platform _OSC capabilities mask, avoid attempting to evaluate _CPC which may fail in that case. Because the OSC_SB_CPC_SUPPORT and OSC_SB_CPCV2_SUPPORT bits are only added to the supported platform capabilities mask on x86, when X86_FEATURE_HWP is supported, allow _CPC to be evaluated regardless in the other cases.

2022-03-17ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNUWerner Sembach
Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working native and video interface. However the default detection mechanism first registers the video interface before unregistering it again and switching to the native interface during boot. This results in a dangling SBIOS request for backlight change for some reason, causing the backlight to switch to ~2% once per boot on the first power cord connect or disconnect event. Setting the native interface explicitly circumvents this buggy behaviour by avoiding the unregistering process.

What prevents this code from being a forever loop is that later there is a separate check for if (queue == 0). The "queue" variable is less than MTL_MAX_RX_QUEUES (8) so it can easily fit in an int type. Any larger value for "queue" would lead to an array overflow when we assign "rx_q = &priv->rx_queue[queue]".

2022-03-17ARM: remove support for NOMMU ARMv4/v5Arnd Bergmann
It is possible to build MMU-less kernels for Cortex-M base microcrontrollers as well as a couple of older platforms that have not been converted to CONFIG_ARCH_MULTIPLATFORM, specifically ep93xx, footbridge, dove, sa1100 and s3c24xx. It seems unlikely that anybody has tested those configurations in recent years, as even building them is frequently broken. A patch I submitted caused another build time regression in this configuration. I sent a patch for that, but it seems better to also remove the option entirely, leaving ARMv7-M as the only supported Arm NOMMU target for simplicity. A couple of platforms have dependencies on CONFIG_MMU, those can all be removed now. Notably, mach-integrator tries to support MMU-less CPU cores, but those have not actually been selectable for a long time. This addresses several build failures in randconfig builds that have accumulated over the years.

2022-03-16net/mlx5e: MPLSoUDP decap, use vlan push_eth instead of peditMaor Dickman
Currently action pedit of source and destination MACs is used to fill the MACs in L2 push step in MPLSoUDP decap offload, this isn't aligned to tc SW which use vlan eth_push action to do this. To fix that, offload support for vlan veth_push action is added together with mpls pop action, and deprecate the use of pedit of MACs.

2022-03-16net: dsa: Never offload FDB entries on standalone portsTobias Waldekranz
If a port joins a bridge that it can't offload, it will fallback to standalone mode and software bridging. In this case, we never want to offload any FDB entries to hardware either. Previously, for host addresses, we would eventually end up in dsa_port_bridge_host_fdb_add, which would unconditionally dereference dp->bridge and cause a segfault.

2022-03-16io_uring: fold evfd signalling under a slower pathPavel Begunkov
Add ->has_evfd flag, which is true IFF there is an eventfd attached, and use it to hide io_eventfd_signal() into __io_commit_cqring_flush() and combine fast checks in a single if. Also, gcc 11.2 wasn't inlining io_cqring_ev_posted() without this change, so helps with that as well.

2022-03-16io_uring: thin down io_commit_cqring()Pavel Begunkov
io_commit_cqring() is currently always under spinlock section, so it's always better to keep it as slim as possible. Move __io_commit_cqring_flush() out of it into ev_posted*(). If fast checks do fail and this post-processing is required, we'll reacquire ->completion_lock, which is fine as we don't care about performance of draining and offset timeouts.

It's never a good idea to put provided buffers without notifying the userspace, it'll lead to userspace leaks, so add io_put_kbuf() in io_req_complete_failed(). The fail helper is called by all sorts of requests, but it's still safe to do as io_put_kbuf() will return 0 in for all requests that don't support and so don't expect provided buffers.
