The branch stable/15 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=37e9b420b23a4d39400a5f8d1fe0c15bc1e04230 commit 37e9b420b23a4d39400a5f8d1fe0c15bc1e04230 Author: Hesham Almatary <Hesham.Almatary@cl.cam.ac.uk> AuthorDate: 2025-11-13 14:57:54 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2025-12-18 22:51:50 +0000 arm64: Fix calculating kernel size for preload metadata Cast &end to vm_offset_t before subtracting VM_MIN_KERNEL_ADDRESS to ensure the resulting size is correct for PRELOAD_PUSH_VALUE. Previously the correct size was effectively divided by sizeof(void *).
