Add CONFIG_IOMMU_IOPF for page fault handling framework and select it from its real consumer. Move iopf function declaration from iommu-sva.h to iommu.h and remove iommu-sva.h as it's empty now. Consolidate all SVA related code into iommu-sva.c: - Move iommu_sva_domain_alloc() from iommu.c to iommu-sva.c. - Move sva iopf handling code from io-pgfault.c to iommu-sva.c. Consolidate iommu_report_device_fault() and iommu_page_response() into io-pgfault.c. Export iopf_free_group() and iopf_group_response() for iopf handlers implemented in modules. Some functions are renamed with more meaningful names. No other intentional functionality changes.

Make iommu_queue_iopf() more generic by making the iopf_group a minimal set of iopf's that an iopf handler of domain should handle and respond to. Add domain parameter to struct iopf_group so that the handler can retrieve and use it directly. Change iommu_queue_iopf() to forward groups of iopf's to the domain's iopf handler. This is also a necessary step to decouple the sva iopf handling code from this interface.

Move iopf_group data structure to iommu.h to make it a minimal set of faults that a domain's page fault handler should handle. Add a new function, iopf_free_group(), to free a fault group after all faults in the group are handled. This function will be made global so that it can be called from other files, such as iommu-sva.c. Move iopf_queue data structure to iommu.h to allow the workqueue to be scheduled out of this file. This will simplify the sequential patches.

The individual iommu driver reports the iommu page faults by calling iommu_report_device_fault(), where a pre-registered device fault handler is called to route the fault to another fault handler installed on the corresponding iommu domain. The pre-registered device fault handler is static and won't be dynamic as the fault handler is eventually per iommu domain. Replace calling device fault handler with iommu_queue_iopf(). After this replacement, the registering and unregistering fault handler interfaces are not needed anywhere. Remove the interfaces and the related data structures to avoid dead code. Convert cookie parameter of iommu_queue_iopf() into a device pointer that is really passed.

The struct dev_iommu contains two pointers, fault_param and iopf_param. The fault_param pointer points to a data structure that is used to store pending faults that are awaiting responses. The iopf_param pointer points to a data structure that is used to store partial faults that are part of a Page Request Group. The fault_param and iopf_param pointers are essentially duplicate. This causes memory waste. Merge the iopf_device_param pointer into the iommu_fault_param pointer to consolidate the code and save memory. The consolidated pointer would be allocated on demand when the device driver enables the iopf on device, and would be freed after iopf is disabled.

The iova_cache_{get,put}() calls really represent top-level lifecycle management for the whole IOVA library, so it's long been rather confusing to have them buried right in the middle of the allocator implementation details. Move them to a more expected position at the end of the file, where it will then also be easier to expand them. With this, we can also move the rcache hotplug handler (plus another stray function) into the rcache portion of the file.

Failure handling in iova_cache_get() is a little messy, and we'd like to add some more to it, so let's tidy up a bit first. By leaving the hotplug handler until last we can take advantage of kmem_cache_destroy() being NULL-safe to have a single cleanup label. We can also improve the error reporting, noting that kmem_cache_create() already screams if it fails, so that one is redundant.

If the file was opened and never read the close will pass a NULL pointer to hrtime_cancel(). - Rewrite of eventfs. Linus wrote a patch series to remove the dentry references in the eventfs_inode and to use ref counting and more of proper VFS interfaces to make it work. - Add warning to put_ei() if ei is not set to free. That means something is about to free it when it shouldn't. - Restructure the eventfs_inode to make it more compact, and remove the unused llist field. - Remove the fsnotify*() funtions for when the inodes were being created in the lookup code. It doesn't make sense to notify about creation just because something is being looked up. - The inode hard link count was not accurate. It was being updated when a file was looked up. The inodes of directories were updating their parent inode hard link count every time the inode was created. That means if memory reclaim cleaned a stale directory inode and the inode was lookup up again, it would increment the parent inode again as well.

Pull ata fix from Niklas Cassel: - Following up on last week's ASMedia ASM1061 43-bit dma_mask quirk, we sent an email to ASMedia developers that have previously been active on the mailing list, asking exactly which SATA controllers that are affected by this hardware limitation. We got a reply that it affects all the SATA controllers in the ASM106x family, thus extend the existing 43-bit dma_mask quirk to apply to all the affected ASMedia SATA controllers. * tag 'ata-6.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: ahci: Extend ASM1061 43-bit DMA address quirk to other ASM106x parts

Another Fujitsu-related patch. In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all.

Pull io_uring fixes from Jens Axboe: - Fix for missing retry for read multishot. If we trigger the execution of it and there's more than one buffer to be read, then we don't always read more than the first one. As it's edge triggered, this can lead to stalls. - Limit inline receive multishot retries for fairness reasons. If we have a very bursty socket receiving data, we still need to ensure we process other requests as well. This is really two minor cleanups, then adding a way for poll reissue to trigger a requeue, and then finally having multishot receive utilize that. - Fix for a weird corner case for non-multishot receive with MSG_WAITALL, using provided buffers, and setting the length to zero (to let the buffer dictate the receive size). * tag 'io_uring-6.8-2024-02-01' of git://git.kernel.dk/linux: io_uring/net: fix sr->len for IORING_OP_RECV with MSG_WAITALL and buffers io_uring/net: limit inline multishot retries io_uring/poll: add requeue return code from poll multishot handling io_uring/net: un-indent mshot retry path in io_recv_finish() io_uring/poll: move poll execution helpers higher up io_uring/rw: ensure poll based multishot read retries appropriately
