src/pages.c:79:33: error: 'MADV_DONTNEED' undeclared (first use in this
 function)
   79 |         if (madvise(addr, size, MADV_DONTNEED) == 0) {

The oldest build error found in the autobuilder logs dates back to 2024:
https://autobuild.buildroot.net/results/adf/adf52f767c92ab1db7b817094a3929f3cf918e82/
so a backport to LTS branches should be considered.
