2022-12-21MIPS: ralink: mt7621: avoid to init common ralink reset controllerSergio Paracuellos
Commit 38a8553b0a22 ("clk: ralink: make system controller node a reset provider") make system controller a reset provider for mt7621 ralink SoCs. Ralink init code also tries to start previous common reset controller which at the end tries to find device tree node 'ralink,rt2880-reset'. mt7621 device tree file is not using at all this node anymore. Hence avoid to init this common reset controller for mt7621 ralink SoCs to avoid 'Failed to find reset controller node' boot error trace error.

2022-12-01mips: ralink: mt7621: do not use kzalloc too earlyJohn Thomson
With CONFIG_SLUB=y, following commit 6edf2576a6cc ("mm/slub: enable debugging memory wasting of kmalloc") mt7621 failed to boot very early, without showing any console messages. This exposed the pre-existing bug of mt7621.c using kzalloc before normal memory management was available. Prior to this slub change, there existed the unintended protection against "kmem_cache *s" being NULL as slab_pre_alloc_hook() happened to return NULL and bailed out of slab_alloc_node(). This allowed mt7621 prom_soc_init to fail in the soc_dev_init kzalloc, but continue booting without the SOC_BUS driver device registered. Console output from a DEBUG_ZBOOT vmlinuz kernel loading, with mm/slub modified to warn on kmem_cache zero or null: zimage at: 80B842A0 810B4BC0 Uncompressing Linux at load address 80001000 Copy device tree to address 80B80EE0 Now, booting the kernel...

However in device tree for CI20 board it was incorrectly marked as "active high". Fix it.

2022-11-12ALSA: memalloc: Try dma_alloc_noncontiguous() at firstTakashi Iwai
The latest fix for the non-contiguous memalloc helper changed the allocation method for a non-IOMMU system to use only the fallback allocator. This should have worked, but it caused a problem sometimes when too many non-contiguous pages are allocated that can't be treated by HD-audio controller. As a quirk workaround, go back to the original strategy: use dma_alloc_noncontiguous() at first, and apply the fallback only when it fails, but only for non-IOMMU case. We'll need a better fix in the fallback code as well, but this workaround should paper over most cases.

2022-11-12ata: libata-core: do not issue non-internal commands once EH is pendingNiklas Cassel
While the ATA specification states that a device should return command aborted for all commands queued after the device has entered error state, since ATA only keeps the sense data for the latest command (in non-NCQ case), we really don't want to send block layer commands to the device after it has entered error state. (Only ATA EH commands should be sent, to read the sense data etc.) Currently, scsi_queue_rq() will check if scsi_host_in_recovery() (state is SHOST_RECOVERY), and if so, it will _not_ issue a command via: scsi_dispatch_cmd() -> host->hostt->queuecommand() (ata_scsi_queuecmd()) -> __ata_scsi_queuecmd() -> ata_scsi_translate() -> ata_qc_issue() Before commit e494f6a72839 ("[SCSI] improved eh timeout handler"), when receiving a TFES error IRQ, the call chain looked like this: ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort() -> ata_qc_complete() -> ata_qc_schedule_eh() -> blk_abort_request() -> blk_rq_timed_out() -> q->rq_timed_out_fn() (scsi_times_out()) -> scsi_eh_scmd_add() -> scsi_host_set_state(shost, SHOST_RECOVERY) Which meant that as soon as an error IRQ was serviced, SHOST_RECOVERY would be set. However, after commit e494f6a72839 ("[SCSI] improved eh timeout handler"), scsi_times_out() will instead call scsi_abort_command() which will queue delayed work, and the worker function scmd_eh_abort_handler() will call scsi_eh_scmd_add(), which calls scsi_host_set_state(shost, SHOST_RECOVERY). So now, after the TFES error IRQ has been serviced, we need to wait for the SCSI workqueue to run its work before SHOST_RECOVERY gets set. It is worth noting that, even before commit e494f6a72839 ("[SCSI] improved eh timeout handler"), we could receive an error IRQ from the time when scsi_queue_rq() checks scsi_host_in_recovery(), to the time when ata_scsi_queuecmd() is actually called. In order to handle both the delayed setting of SHOST_RECOVERY and the window where we can receive an error IRQ, add a check against ATA_PFLAG_EH_PENDING (which gets set when servicing the error IRQ), inside ata_scsi_queuecmd() itself, while holding the ap->lock. (Since the ap->lock is held while servicing IRQs.)

Pull kvm "This is a pretty large diffstat for this time of the release. The main culprit is a reorganization of the AMD assembly trampoline, allowing percpu variables to be accessed early. This is needed for the return stack depth tracking retbleed mitigation that will be in 6.2, but it also makes it possible to tighten the IBRS restore on vmexit. The latter change is a long tail of the spectrev2/retbleed patches (the corresponding Intel change was simpler and went in already last June), which is why I am including it right now instead of sharing a topic branch with tip. Being assembly and being rich in comments makes the line count balloon a bit, but I am pretty confident in the change (famous last words) because the reorganization actually makes everything simpler and more understandable than before. It has also had external review and has been tested on the aforementioned 6.2 changes, which explode quite brutally without the fix.

2022-11-11io_uring/poll: fix double poll req->flags racesPavel Begunkov
io_poll_double_prepare() | io_poll_wake() | poll->head = NULL smp_load(&poll->head); /* NULL */ | flags = req->flags; | | req->flags &= ~SINGLE_POLL; req->flags = flags | DOUBLE_POLL | The idea behind io_poll_double_prepare() is to serialise with the first poll entry by taking the wq lock. However, it's not safe to assume that io_poll_wake() is not running when we can't grab the lock and so we may race modifying req->flags. Skip double poll setup if that happens. It's ok because the first poll entry will only be removed when it's definitely completing, e.g. pollfree or oneshot with a valid mask.
