That's true. Converting both arm64 to powerpc to kvmalloc/kvfree is a good option. I don't think it's that much better though, because kexec_file_load() is called infrequently and doesn't need to be fast so the vmalloc() overhead isn't important in practice. -- Thiago Jung Bauermann IBM Linux Technology Center
