Move the core logic into a helper, so we can use it for changing other permissions. We also change the logic to align start down, and end up. This means calling the function with a range will expand that range to be at least 1 mmu_linear_psize page in size. We need that so we can use it on __init_begin ... __init_end which is not a full page in size. This should always work for _stext/__init_begin, because we align __init_begin to _stext + 16M in the linker script. Signed-off-by:
