[ARM] fix naming of MODULE_START / MODULE_END
As of 73bdf0a60e607f4b8ecc5aec597105976565a84f, the kernel needs to know where modules are located in the virtual address space. On ARM, we located this region between MODULE_START and MODULE_END. Unfortunately, everyone else calls it MODULES_VADDR and MODULES_END. Update ARM to use the same naming, so is_vmalloc_or_module_addr() can work properly. Also update the comment on mm/vmalloc.c to reflect that ARM also places modules in a separate region from the vmalloc space. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
