hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I8UT5S CVE: NA
--------------------------------
There is no extra bit in pageflags for new flag on x86_64. Since 256 nodes is enough for x86_64, reduce CONFIG_NODES_SHIFT to 8 to obtain two unused bits on x86_64.
On arm64, 128 node is not enough, so raise CONFIG_NODES_SHIFT to 8.
