Michael Ellerman	938f846492	provide linux/set_memory.h ... Currently code that wants to use set_memory_ro() etc, needs to include asm/set_memory.h, which doesn't exist on all arches. Some code knows it only builds on arches which have the header, other code guards the inclusion with an #ifdef, neither is ideal. So create linux/set_memory.h. This always exists, so users don't need an #ifdef just to include the header. When CONFIG_ARCH_HAS_SET_MEMORY=y it includes asm/set_memory.h, otherwise it provides empty non-failing implementations.
