Fix a memcpy that should be a text_poke (in apply_alternatives). Use kernel_wp_save/kernel_wp_restore in text_poke to support DEBUG_RODATA correctly and so the CPU HOTPLUG special case can be removed. Add text_poke_early, for alternatives and paravirt boot-time and module load time patching. Changelog: - Fix text_set and text_poke alignment check (mixed up bitwise and and or) - Remove text_set - Export add_nops, so it can be used by others. - Document text_poke_early. - Remove clflush, since it breaks some VIA architectures and is not strictly necessary. - Add kerneldoc to text_poke and text_poke_early. - Create a second vmap instead of using the WP bit to support Xen and VMI. - Move local_irq disable within text_poke and text_poke_early to be able to be sleepable in these functions.
