Laura Abbott 1404d6f13e arm64: dump: Add checking for writable and exectuable pages ... Page mappings with full RWX permissions are a security risk. x86 has an option to walk the page tables and dump any bad pages. (See e1a58320a3 ("x86/mm: Warn on W^X mappings")). Add a similar implementation for arm64.
