hulk inclusion
category: feature
bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/I4QSHG
CVE: NA

--------------------------------

When THP is enabled, the allocation of a page(order=0) may be converted to
an allocation of pages(order>0). In this case, the allocation will skip the
dhugetlb_pool. When we want to use dynamic hugetlb feature, we have to
disable THP for now.
