Pull RISC-V fixes from Paul Walmsley: - Call flush_cache_vmap() after populating new vmemmap pages, on all architectures. This avoids spurious faults on RISC-V microarchitectures that cache PTEs marked as non-present - Disable LTO for the vDSO to prevent the compiler from eliding functions that are used, but which don't appear to be - Fix an issue with libgcc's unwinder and signal handlers by dropping an unnecessary CFI landing pad instruction in __vdso_rt_sigreturn (similar to what was done on ARM64) - Avoid reading uninitialized memory under certain conditions in hwprobe_get_cpus() - Save some memory and I$ when CONFIG_DYNAMIC_FTRACE=n by avoiding our four-byte function alignment requirement in that case - Avoid clang warnings about null-pointer arithmetic in the I/O-port accessor macros (inb, outb, etc.) by ifdeffing them out when !CONFIG_HAS_IOPORT - Make the build of the lazy TLB flushing code in the vmalloc path depend on CONFIG_64BIT and CONFIG_MMU (since those platforms are the only ones that use it) * tag 'riscv-for-linus-7.2-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: hwprobe: Avoid uninitialized read in hwprobe_get_cpus() arch/riscv: vdso: remove CFI landing pad from rt_sigreturn riscv: vdso: Do not use LTO for the vDSO riscv: io: avoid null-pointer arithmetic in PIO helpers riscv: Gate FUNCTION_ALIGNMENT_4B on DYNAMIC_FTRACE mm/sparse-vmemmap: flush_cache_vmap() after hotplugging vmemmap riscv: mm: Make mark_new_valid_map() stuff depend on 64BIT && MMU
Pull block fixes from Jens Axboe: - Fixes for the dio bounce buffer helpers: correct the alignment of bounced dio read bios to avoid a double unpin, handle huge zero folios in bio_free_folios(), and don't warn on the larger-order folio attempts in the greedy allocation path. - Try a slab allocation in bio_alloc_bioset() before falling back to the mempool, restoring the previous behavior for non-sleeping allocations from a cache-enabled bioset. - Serialize elevator changes for the same queue using the writer lock. - Fix a race in blk_time_get_ns() where a task preempted between setting PF_BLOCK_TS and the cached-timestamp reload could return 0. - blk-cgroup fix for leaks and the online flag on a radix_tree_insert() failure in blkg_create(). - Free the copied pages when blk_rq_map_kern() fails after blk_rq_append_bio() rejects the bio. - Remove manually added partitions on loop device detach, fixing dead partition devices left behind and a subsequent LOOP_CONFIGURE -EBUSY - Bound the AIX partition lvd scan to the sector that was actually read. - Show the block operation in error injection rules (Jackie) * tag 'block-7.2-20260717' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: block: fix aligning of bounced dio read bios block: handle huge zero folios in bio_free_folios block: try slab allocation in bio_alloc_bioset() before mempool block: show operation in error injection rules block: serialize elevator changes for the same queue using a writer lock block: free copied pages when blk_rq_map_kern() fails block: do not warn when doing greedy allocation in folio_alloc_greedy() partitions: aix: bound the lvd scan to one sector blk-cgroup: fix leaks and online flag on radix_tree_insert failure loop: remove manually added partitions on detach block: fix race in blk_time_get_ns() returning 0
Pull io_uring fixes from Jens Axboe: - Fix a use-after-free in the bpf-ops struct_ops path, where the same io_uring_bpf_ops map could be registered more than once. - Fix the deferred iovec free for the provided-buffer grow path, which could leave the caller with a dangling iovec and result in repeated frees. Follow-up to the earlier fix in this series. - Zero-check the unused addr3/pad2 SQE fields for unlinkat * tag 'io_uring-7.2-20260717' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: io_uring/bpf-ops: reject re-registration of an already-bound ops io_uring/fs: check unused sqe fields for unlinkat io_uring/kbuf: free the replaced iovec after a successful grow
