One possibility that works is sticking it right below LOAD_PHYSICAL_ADDR: +static void add_kaslr_setup_data(struct boot_params *params, + u8 *output, __u8 enabled) { + /* + * Stick it right under LOAD_PHYSICAL_ADDR + */ + ksd = (struct setup_data *)(output - 2 * sizeof(struct setup_data)); output is LOAD_PHYSICAL_ADDR AFAICT and is the minimum kASLR considers so right below it should work: https://lkml.kernel.org/r/20150228105049.GA11038@xxxxxxx -- Regards/Gruss, Boris.
