Mirror change suggested in legacy HDaudio driver. On SKL+ Intel platforms, the driver selection is handled by the snd_intel_dspcfg, and when the HDaudio legacy driver is not selected, be it with the auto-selection or user preferences with a kernel parameter, the probe aborts with no logs, only a -ENODEV return value. Having no dmesg trace, even with dynamic debug enabled, makes support more complicated than it needs to be, and even experienced users can be fooled. A simple dev_dbg() trace solves this problem.

Merge series "ASoC: Intel: machine driver updates for 5.10" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: This series updates the tables used to select SoundWire configurations for CometLake and TigerLake, and adds support for SDCA (SoundWire Device Class for Audio) codecs in the common machine driver. These codec drivers are still being tested on early silicon/boards and will be contributed at a later time. For TigerLake Chromebooks a new DMI quirk is added, as well as a means to override the topology names. A pm_runtime fix is also provided to deal with playback/capture dependencies with an amplifier w/ feedback. I also included a minor codec correction for the TGL amplifier.

Add topology filename override based on system DMI data matching, typically to account for a different hardware layout. In ACPI based systems, the tplg_filename is pre-defined in an ACPI machine table. When a DMI quirk is detected, the sof_pdata->tplg_filename is not set with the hard-coded ACPI value, and instead is set with the DMI-specific filename.

When the playback & capture streams are stopped simultaneously, the SOF PCI device will remain pm_runtime active. The root-cause is a race condition with two threads reaching the trigger function at the same time. They see another stream is active so the dapm pin is not disabled, so the codec remains active as well as the parent PCI device. For max98373, the capture stream provides feedback when playback is working and it is unused when playback is stopped. So the dapm pin should be set only when playback is active.

Pull x86 fix from Thomas Gleixner: "A single fix for x86 which removes the RDPID usage from the paranoid entry path and unconditionally uses LSL to retrieve the CPU number. RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values and restores them either when leaving the run loop, on preemption or when going out to user space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest value and before the lazy restore any exception using the paranoid entry will read the guest value and use it as CPU number to retrieve the GSBASE value for the current CPU when FSGSBASE is enabled. As RDPID is only used in that particular entry path, there is no reason to burden VMENTER/EXIT with two extra MSR writes. Remove the RDPID optimization, which is not even backed by numbers from the paranoid entry path instead" * tag 'x86-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Do not use RDPID in paranoid entry to accomodate KVM

Pull networking fixes from David Miller: "Nothing earth shattering here, lots of small fixes (f.e. missing RCU protection, bad ref counting, missing memset(), etc.) all over the place: 1) Use get_file_rcu() in task_file iterator, from Yonghong Song. 2) There are two ways to set remote source MAC addresses in macvlan driver, but only one of which validates things properly. Fix this. From Alvin Šipraga. 3) Missing of_node_put() in gianfar probing, from Sumera Priyadarsini. 4) Preserve device wanted feature bits across multiple netlink ethtool requests, from Maxim Mikityanskiy. 5) Fix rcu_sched stall in task and task_file bpf iterators, from Yonghong Song. 6) Avoid reset after device destroy in ena driver, from Shay Agroskin. 7) Missing memset() in netlink policy export reallocation path, from Johannes Berg. 8) Fix info leak in __smc_diag_dump(), from Peilin Ye. 9) Decapsulate ECN properly for ipv6 in ipv4 tunnels, from Mark Tomlinson. 10) Fix number of data stream negotiation in SCTP, from David Laight. 11) Fix double free in connection tracker action module, from Alaa Hleihel. 12) Don't allow empty NHA_GROUP attributes, from Nikolay Aleksandrov" * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (46 commits) net: nexthop: don't allow empty NHA_GROUP bpf: Fix two typos in uapi/linux/bpf.h net: dsa: b53: check for timeout tipc: call rcu_read_lock() in tipc_aead_encrypt_done() net/sched: act_ct: Fix skb double-free in tcf_ct_handle_fragments() error flow net: sctp: Fix negotiation of the number of data streams. dt-bindings: net: renesas, ether: Improve schema validation gre6: Fix reception with IP6_TNL_F_RCV_DSCP_COPY hv_netvsc: Fix the queue_mapping in netvsc_vf_xmit() hv_netvsc: Remove "unlikely" from netvsc_select_queue bpf: selftests: global_funcs: Check err_str before strstr bpf: xdp: Fix XDP mode when no mode flags specified selftests/bpf: Remove test_align leftovers tools/resolve_btfids: Fix sections with wrong alignment net/smc: Prevent kernel-infoleak in __smc_diag_dump() sfc: fix build warnings on 32-bit net: phy: mscc: Fix a couple of spelling mistakes "spcified" -> "specified" libbpf: Fix map index used in error message net: gemini: Fix missing free_netdev() in error path of gemini_ethernet_port_probe() net: atlantic: Use readx_poll_timeout() for large timeout ...

When adding a new fd to an epoll, and that this new fd is an epoll fd itself, we recursively scan the fds attached to it to detect cycles, and add non-epool files to a "check list" that gets subsequently parsed. However, this check list isn't completely safe when deletions can happen concurrently. To sidestep the issue, make sure that a struct file placed on the check list sees its f_count increased, ensuring that a concurrent deletion won't result in the file disapearing from under our feet.
