This reverts commit a584c7734a4dd050451fcdd65c66317e15660e81 which is
commit 91b80cc5b39f00399e8e2d17527cad2c7fa535e2 upstream.

This fixes the following build error:

map_hugetlb.c:79:25: warning: implicit declaration of function 'default_huge_page_size' [-Wimplicit-function-declaration]
79 |         hugepage_size = default_huge_page_size();
