Subject: [PATCH] arm64: mm: support setting page attributes for debugging

euleros inclusion
category: feature
feature: Memory debug feature

When pagealloc debug is enabled, block mappings or contiguous hints are
no longer used for linear address area. Therefore, support setting page
attributes in this case is useful for debugging memory corruption
problems.
