memalign() is obsolete according to its manpage.

Replace memalign() with posix_memalign() and remove malloc.h include that was there for memalign().

Comment does not apply.

As a pointer is passed into posix_memalign(), initialize *p to NULL to silence a warning about the function's return value being used as uninitialized (which is not valid anyway because the error is properly checked before p is returned).

• int ret;

• one_page = memalign(pmd_pagesize, len);
• if (!one_page) {

• ret = posix_memalign((void **)(&one_page), pmd_pagesize, len);

ret = posix_memalign((void **)&one_page, pmd_pagesize, len);

Should do.

• if (ret < 0) { printf("Fail to allocate memory\n"); exit(EXIT_FAILURE); }
