CVE: NA

Reference: https://gitee.com/openeuler/kernel/commit/74bfdf157f1fd40b5d7966d1d94fcd690ad93a3e



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

Previous memory allocation in memblock for hugetlb may use mirrored or
non-mirrored memory depends on the system's memory status. However this is
not suitable if hugetlb user want to alloc memory from non-mirrored memory
if kernelcore=mirror is enabled.

In order to solve this problem, hugetlb use MEMBLOCK_NOMIRROR flag to alloc
memory from non-mirrored region without fallback to mirrored region.

[ jz: adapt to hugepage_no_mirror by checking "hugepage_no_mirror"
      instead of "mem_reliable_is_enabled()", and fix typo "min_addr" ]
