    arm, xtensa: simplify initialization of high memory pages · cddb5ddf
    Mike Rapoport authored
    free_highpages() in both arm and xtensa essentially open-code
    for_each_free_mem_range() loop to detect high memory pages that were not
    reserved and that should be initialized and passed to the buddy allocator.
    
    Replace open-coded implementation of for_each_free_mem_range() with usage
    of memblock API to simplify the code.
