Greetings,

Since commit a8e53c151fe7 "(ARM: 8737/1: mm: dump: add checking for
writable and executable)" I've been seeing the following appear on my
arm32 kernel:

arm/mm: Found insecure W+X mapping at address 0xf087d000
...
Checked W+X mappings: FAILED, 1 W+X pages found

As I haven't seen others report this I assume it's something unique to
my kernel configuration. How do I debug what is causing the insecure
page?

Best regards,

Tim
