Hi,

This is v4 of the implementation to check for writable and executable pages on
arm64. This version contains a review from Ard and makes the UXN page count
a separate variable. Overall, minor changes.

Thanks,
Laura

Laura Abbott (4):
  arm64: dump: Make ptdump debugfs a separate option
  arm64: dump: Make the page table dumping seq_file optional
  arm64: dump: Remove max_addr
  arm64: dump: Add checking for writable and exectuable pages
