commit 4ed990e5b97a61f29f929bdeb36c5b2abb547a64
Author: Joseph Myers <joseph@codesourcery.com>

    Add MADV_POPULATE_READ and MADV_POPULATE_WRITE from Linux 5.14 to bits/mman-linux.h
    
    Linux 5.14 adds constants MADV_POPULATE_READ and MADV_POPULATE_WRITE
    (with the same values on all architectures).  Add these to glibc's
    bits/mman-linux.h.
    
    Tested for x86_64.
    
    (cherry picked from commit 3561106278cddd2f007bd27fd4c3e90caaf14b43)
