[PATCH 0/3] Page protections for arm64

[Laura Abbott]

Hi,

These are a couple of semi-related patches to set memory on arm64 to something
other than read/write/execute everywhere. The CONFIG_DEBUG_SET_MODULE_RONX is
actually v2 of the previous patch[1] but it seemed reasonable to put this with
the other work to map regular memory with better protections. The direction
for the arm64 work is roughly based on arm.

Thanks,
Laura
