The `struct kho_vmalloc` defines the in-memory layout for preserving vmalloc regions across kexec. This layout is a contract between kernels and part of the KHO ABI. To reflect this relationship, the related structs and helper macros are relocated to the ABI header, `include/linux/kho/abi/kexec_handover.h`. This move places the structure's definition under the protection of the KHO_FDT_COMPATIBLE version string. The structure and its components are now also documented within the ABI header to describe the contract and prevent ABI breaks.
