af_unix: Introduce SO_INQ.
We have an application that uses almost the same code for TCP and AF_UNIX (SOCK_STREAM). TCP can use TCP_INQ, but AF_UNIX doesn't have it and requires an extra syscall, ioctl(SIOCINQ) or getsockopt(SO_MEMINFO) as an alternative. Let's introduce the generic version of TCP_INQ. If SO_INQ is enabled, recvmsg() will put a cmsg of SCM_INQ that contains the exact value of ioctl(SIOCINQ). The cmsg is also included when msg->msg_get_inq is non-zero to make sockets io_uring-friendly. Note that SOCK_CUSTOM_SOCKOPT is flagged only for SOCK_STREAM to override setsockopt() for SOL_SOCKET. By having the flag in struct unix_sock, instead of struct sock, we can later add SO_INQ support for TCP and reuse tcp_sk(sk)->recvmsg_inq. Note also that supporting custom getsockopt() for SOL_SOCKET will need preparation for other SOCK_CUSTOM_SOCKOPT users (UDP, vsock, MPTCP).

mm: pgtable: fix pte_swp_exclusive
Make pte_swp_exclusive return bool instead of int. This will better reflect how pte_swp_exclusive is actually used in the code. This fixes swap/swapoff problems on Alpha due pte_swp_exclusive not returning correct values when _PAGE_SWP_EXCLUSIVE bit resides in upper 32-bits of PTE (like on alpha).

- The 11 patch series "Add folio_mk_pte()" from Matthew Wilcox
simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - The 8 patch series "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - The 3 patch series "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - The 2 patch series "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - The 8 patch series "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - The 6 patch series "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - The 3 patch series "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap. This permits CRIU to more efficiently get at the info about guard regions. - The 2 patch series "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan implements that fix. No runtime effect is expected because validate_page_before_insert() happens to fix up this error. - The 3 patch series "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David Hildenbrand basically brings uprobe text poking into the current decade. Remove a bunch of hand-rolled implementation in favor of using more current facilities. - The 3 patch series "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman Khandual provides enhancements and generalizations to the pte dumping code. This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - The 12 patch series "Always call constructor for kernel page tables" from Kevin Brodsky "ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables". This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - The 9 patch series "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - The 3 patch series "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - The 4 patch series "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - The 6 patch series "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - The 3 patch series "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - The 3 patch series ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support".

"This is useful for isolating workloads on a multi-tenant system from certain classes of memory more consistently." - The 2 patch series ""Clean up split_huge_pmd_locked() and remove unnecessary folio pointers" from Gavin Guo provides minor cleanups and efficiency gains in in the huge page splitting and migrating code. - The 3 patch series "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache for `struct mem_cgroup', yielding improved memory utilization. - The 4 patch series "add max arg to swappiness in memory.reclaim and lru_gen" from Zhongkun He adds a new "max" argument to the "swappiness=" argument for memory.reclaim MGLRU's lru_gen. This directs proactive reclaim to reclaim from only anon folios rather than file-backed folios. - The 17 patch series "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the first step on the path to permitting the kernel to maintain existing VMs while replacing the host kernel via file-based kexec. At this time only memblock's reserve_mem is preserved. - The 7 patch series "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides and uses a smarter way of looping over a pfn range. By skipping ranges of invalid pfns. - The 2 patch series "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning when a task is pinned a single NUMA mode. Dramatic performance benefits were seen in some real world cases. - The 2 patch series "JFS: Implement migrate_folio for jfs_metapage_aops" from Shivank Garg addresses a warning which occurs during memory compaction when using JFS. - The 4 patch series "move all VMA allocation, freeing and duplication logic to mm" from Lorenzo Stoakes moves some VMA code from kernel/fork.c into the more appropriate mm/vma.c. - The 6 patch series "mm, swap: clean up swap cache mapping helper" from Kairui Song provides code consolidation and cleanups related to the folio_index() function. - The 2 patch series "mm/gup: Cleanup memfd_pin_folios()" from Vishal Moola does that. - The 8 patch series "memcg: Fix test_memcg_min/low test failures" from Waiman Long addresses some bogus failures which are being reported by the test_memcontrol selftest. - The 3 patch series "eliminate mmap() retry merge, add .mmap_prepare hook" from Lorenzo Stoakes commences the deprecation of file_operations.mmap() in favor of the new file_operations.mmap_prepare().

This is a step along the way to making memcg and objcg charging NMI-safe, which is a BPF requirement. - The 6 patch series "mm/damon: minor fixups and improvements for code, tests, and documents" from SeongJae Park is "yet another batch of miscellaneous DAMON changes.

Networking changes for 6.16.
Core ---- - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter --------- - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF --- - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols --------- - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API ---------- - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling ----------------- - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP. New hardware / drivers ---------------------- - OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation. - Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC. - Broadcom asp-v3.0 ethernet driver. - AMD Renoir ethernet device. - ReakTek MT9888 2.5G ethernet PHY driver. - Aeonsemi 10G C45 PHYs driver. Drivers ------- - Ethernet high-speed NICs: - nVidia/Mellanox (mlx5): - refactor the stearing table handling to reduce significantly the amount of memory used - add support for complex matches in H/W flow steering - improve flow streeing error handling - convert to netdev instance locking - Intel (100G, ice, igb, ixgbe, idpf): - ice: add switchdev support for LLDP traffic over VF - ixgbe: add firmware manipulation and regions devlink support - igb: introduce support for frame transmission premption - igb: adds persistent NAPI configuration - idpf: introduce RDMA support - idpf: add initial PTP support - Meta (fbnic): - extend hardware stats coverage - add devlink dev flash support - Broadcom (bnxt): - add support for RX-side device memory TCP - Wangxun (txgbe): - implement support for udp tunnel offload - complete PTP and SRIOV support for AML 25G/10G devices - Ethernet NICs embedded and virtual: - Google (gve): - add device memory TCP TX support - Amazon (ena): - support persistent per-NAPI config - Airoha: - add H/W support for L2 traffic offload - add per flow stats for flow offloading - RealTek (rtl8211): add support for WoL magic packet - Synopsys (stmmac): - dwmac-socfpga 1000BaseX support - add Loongson-2K3000 support - introduce support for hardware-accelerated VLAN stripping - Broadcom (bcmgenet): - expose more H/W stats - Freescale (enetc, dpaa2-eth): - enetc: add MAC filter, VLAN filter RSS and loopback support - dpaa2-eth: convert to H/W timestamping APIs - vxlan: convert FDB table to rhashtable, for better scalabilty - veth: apply qdisc backpressure on full ring to reduce TX drops - Ethernet switches: - Microchip (kzZ88x3): add ETS scheduler support - Ethernet PHYs: - RealTek (rtl8211): - add support for WoL magic packet - add support for PHY LEDs - CAN: - Adds RZ/G3E CANFD support to the rcar_canfd driver. - Preparatory work for CAN-XL support. - Add self-tests framework with support for CAN physical interfaces. - WiFi: - mac80211: - scan improvements with multi-link operation (MLO) - Qualcomm (ath12k): - enable AHB support for IPQ5332 - add monitor interface support to QCN9274 - add multi-link operation support to WCN7850 - add 802.11d scan offload support to WCN7850 - monitor mode for WCN7850, better 6 GHz regulatory - Qualcomm (ath11k): - restore hibernation support - MediaTek (mt76): - WiFi-7 improvements - implement support for mt7990 - Intel (iwlwifi): - enhanced multi-link single-radio (EMLSR) support on 5 GHz links - rework device configuration - RealTek (rtw88): - improve throughput for RTL8814AU - RealTek (rtw89): - add multi-link operation support - STA/P2P concurrency improvements - support different SAR configs by antenna - Bluetooth: - introduce HCI Driver protocol - btintel_pcie: do not generate coredump for diagnostic events - btusb: add HCI Drv commands for configuring altsetting - btusb: add RTL8851BE device 0x0bda:0xb850 - btusb: add new VID/PID 13d3/3584 for MT7922 - btusb: add new VID/PID 13d3/3630 and 13d3/3613 for MT7925 - btnxpuart: implement host-wakeup feature Signed-off-by: Paolo Abeni <pabeni@redhat.com> -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEEg1AjqC77wbdLX2LbKSR5jcyPE6QFAmg3D64SHHBhYmVuaUBy ZWRoYXQuY29tAAoJECkkeY3MjxOkcIsQAK2eEc+BxQer975wzvtMg6gF9eoex4a+ rZ7jxfDzDtNvTauoQsrpehDZp0FnySaVGCU36lHGB2OvDnhCpPc5hXzKDWQpOuqQ SHrGG3/6FTbdTG/HfHUcbNyrUzIf53SADSObiQ3qg4gyEQ3sCpcOKtVtMcU8rvsY /HqMnsJWFaROUMjMtCcnUSgjmeY9kBvha3sTXUqgeRugEOCvZD7z4rpqFIcQqHw7 e2Fi8dwIXEYNxqPp6MRq2qdyUTewCRruE8ZIMAFuhtfYeMElUZMPlqlMENX3AzTQ cr0EgwcFOUxRA7oZRxhoBNBsVXavtSpQr4ZDoWplxP4aQ37n5tc1E9Q72axpB/Og FbJRl6GvWYnCd8071BczgmfHlKaTAigPvt2Z4r6JjM5I/Bij/IZ3k+On1OTuOAj/ EqfFkdZ0a5cfKrwUMP+oSGtSAywkMVUtnIKJlZeRbjSj2432sCfe2jVAlS8ELM43 3LUgXYrAKtA87g171LlsRu5EEpI5QmqPb+i5LpPlEXe2TJEgPisyfecJ3NafF/2+ j575lm+TFNm9NTNhGGjDPEvw0djI5wSGGMe9J4gC74eWi6s5t6C4cuUf84TKWdwR x+9H0IB7rfFncAwXHJuUUtzd+fPHaYzs5dDGbSgMQOXr1cr1wlubCK8mQ1r/Wt/a 3GjFIOQKW2Q5 =t/Tz -----END PGP SIGNATURE----- Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU.

It also makes (implicit) use of the new SO_PEERPIDFD ability to hand out pidfds for reaped peer tasks The new coredump socket will allow userspace to not have to rely on usermode helpers for processing coredumps and provides a saf way to handle them instead of relying on super privileged coredumping helpers This will also be significantly more lightweight since the kernel doens't have to do a fork()+exec() for each crashing process to spawn a usermodehelper. Instead the kernel just connects to the AF_UNIX socket and userspace can process it concurrently however it sees fit. Support for userspace is incoming starting with systemd-coredump There's more work coming in that direction next cycle. The rest below goes into some details and background Coredumping currently supports two modes: (1) Dumping directly into a file somewhere on the filesystem. (2) Dumping into a pipe connected to a usermode helper process spawned as a child of the system_unbound_wq or kthreadd For simplicity I'm mostly ignoring (1). There's probably still some users of (1) out there but processing coredumps in this way can be considered adventurous especially in the face of set*id binaries The most common option should be (2) by now. It works by allowing userspace to put a string into /proc/sys/kernel/core_pattern like: |/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h The "|" at the beginning indicates to the kernel that a pipe must be used. The path following the pipe indicator is a path to a binary that will be spawned as a usermode helper process. Any additional parameters pass information about the task that is generating the coredump to the binary that processes the coredump In the example the core_pattern shown causes the kernel to spawn systemd-coredump as a usermode helper. There's various conceptual consequences of this (non-exhaustive list): - systemd-coredump is spawned with file descriptor number 0 (stdin) connected to the read-end of the pipe. All other file descriptors are closed. That specifically includes 1 (stdout) and 2 (stderr). This has already caused bugs because userspace assumed that this cannot happen (Whether or not this is a sane assumption is irrelevant) - systemd-coredump will be spawned as a child of system_unbound_wq. So it is not a child of any userspace process and specifically not a child of PID 1. It cannot be waited upon and is in a weird hybrid upcall which are difficult for userspace to control correctly - systemd-coredump is spawned with full kernel privileges. This necessitates all kinds of weird privilege dropping excercises in userspace to make this safe - A new usermode helper has to be spawned for each crashing process This adds a new mode: (3) Dumping into an AF_UNIX socket Userspace can set /proc/sys/kernel/core_pattern to: @/path/to/coredump.socket The "@" at the beginning indicates to the kernel that an AF_UNIX coredump socket will be used to process coredumps The coredump socket must be located in the initial mount namespace. When a task coredumps it opens a client socket in the initial network namespace and connects to the coredump socket: - The coredump server uses SO_PEERPIDFD to get a stable handle on the connected crashing task. The retrieved pidfd will provide a stable reference even if the crashing task gets SIGKILLed while generating the coredump. That is a huge attack vector right now - By setting core_pipe_limit non-zero userspace can guarantee that the crashing task cannot be reaped behind it's back and thus process all necessary information in /proc/<pid>. The SO_PEERPIDFD can be used to detect whether /proc/<pid> still refers to the same process The core_pipe_limit isn't used to rate-limit connections to the socket. This can simply be done via AF_UNIX socket directly - The pidfd for the crashing task will contain information how the task coredumps. The PIDFD_GET_INFO ioctl gained a new flag PIDFD_INFO_COREDUMP which can be used to retreive the coredump information If the coredump gets a new coredump client connection the kernel guarantees that PIDFD_INFO_COREDUMP information is available. Currently the following information is provided in the new @coredump_mask extension to struct pidfd_info: * PIDFD_COREDUMPED is raised if the task did actually coredump * PIDFD_COREDUMP_SKIP is raised if the task skipped coredumping (e.g., undumpable) * PIDFD_COREDUMP_USER is raised if this is a regular coredump and doesn't need special care by the coredump server * PIDFD_COREDUMP_ROOT is raised if the generated coredump should be treated as sensitive and the coredump server should restrict access to the generated coredump to sufficiently privileged users" * tag 'vfs-6.16-rc1.coredump' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: mips, net: ensure that SOCK_COREDUMP is defined selftests/coredump: add tests for AF_UNIX coredumps selftests/pidfd: add PIDFD_INFO_COREDUMP infrastructure coredump: validate socket name as it is written coredump: show supported coredump modes pidfs, coredump: add PIDFD_INFO_COREDUMP coredump: add coredump socket coredump: reflow dump helpers a little coredump: massage do_coredump() coredump: massage format_corename() |

af_unix: Introduce SO_PASSRIGHTS.
As long as recvmsg() or recvmmsg() is used with cmsg, it is not possible to avoid receiving file descriptors via SCM_RIGHTS. This behaviour has occasionally been flagged as problematic, as it can be (ab)used to trigger DoS during close(), for example, by passing a FUSE-controlled fd or a hung NFS fd. For instance, as noted on the uAPI Group page [0], an untrusted peer could send a file descriptor pointing to a hung NFS mount and then close it. Once the receiver calls recvmsg() with msg_control, the descriptor is automatically installed, and then the responsibility for the final close() now falls on the receiver, which may result in blocking the process for a long time. Regarding this, systemd calls cmsg_close_all() [1] after each recvmsg() to close() unwanted file descriptors sent via SCM_RIGHTS. However, this cannot work around the issue at all, because the final fput() may still occur on the receiver's side once sendmsg() with SCM_RIGHTS succeeds. Also, even filtering by LSM at recvmsg() does not work for the same reason. Thus, we need a better way to refuse SCM_RIGHTS at sendmsg(). Let's introduce SO_PASSRIGHTS to disable SCM_RIGHTS. Note that this option is enabled by default for backward compatibility.

MIPS: SMP: Move the AP sync point before the non-parallel aware functions
When CONFIG_HOTPLUG_PARALLEL is enabled, the code executing before
cpuhp_ap_sync_alive() is executed in parallel, while after it is
serialized. The functions set_cpu_sibling_map() and set_cpu_core_map()
were not designed to be executed in parallel, so by moving the
cpuhp_ap_sync_alive() before cpuhp_ap_sync_alive(), we then ensure
they will be called serialized.
The measurement done on EyeQ5 did not show any relevant boot time
increase after applying this patch.

MIPS: Switch to irq_domain_create_*()
irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

mm: pass mm down to pagetable_{pte,pmd}_ctor
Patch series "Always call constructor for kernel page tables", v2.
There has been much confusion around exactly when page table
constructors/destructors (pagetable_*_[cd]tor) are supposed to be called.
They were initially introduced for user PTEs only (to support split page
table locks), then at the PMD level for the same purpose. Accounting was
added later on, starting at the PTE level and then moving to higher levels
(PMD, PUD). Finally, with my earlier series "Account page tables at all
levels" [1], the ctor/dtor is run for all levels, all the way to PGD.
I thought this was the end of the story, and it hopefully is for user
pgtables, but I was wrong for what concerns kernel pgtables. The current
situation there makes very little sense:
* At the PTE level, the ctor/dtor is not called (at least in the generic
implementation). Specific helpers are used for kernel pgtables at this
level (pte_{alloc,free}_kernel()) and those have never called the
ctor/dtor, most likely because they were initially irrelevant in the
kernel case.
* At all other levels, the ctor/dtor is normally called. This is
potentially wasteful at the PMD level (more on that later).
This series aims to ensure that the ctor/dtor is always called for kernel
pgtables, as it already is for user pgtables. Besides consistency, the
main motivation is to guarantee that ctor/dtor hooks are systematically
called; this makes it possible to insert hooks to protect page tables [2],
for instance. There is however an extra challenge: split locks are not
used for kernel pgtables, and it would therefore be wasteful to initialise
them (ptlock_init()).
It is worth clarifying exactly when split locks are used. They clearly
are for user pgtables, but as illustrated in commit

lib/crc: make arch-optimized code use subsys_initcall
Make the architecture-optimized CRC code do its CPU feature checks in subsys_initcalls instead of arch_initcalls. This makes it consistent with arch/*/lib/crypto/ and ensures that it runs after initcalls that possibly could be a prerequisite for kernel-mode FPU, such as x86's xfd_update_static_branch() and loongarch's init_euen_mask(). Note: as far as I can tell, x86's xfd_update_static_branch() isn't *actually* needed for kernel-mode FPU. loongarch's init_euen_mask() is needed to enable save/restore of the vector registers, but loongarch doesn't yet have any CRC or crypto code that uses vector registers anyway. Regardless, let's be consistent with arch/*/lib/crypto/ and robust against any potential future dependency on an arch_initcall.
