Did a quick look on this, looks like PROT_WRITE implies PROT_READ on x86, have to verify the same is true on arm64. Will make some test cases.

The hardware doesn't even let you map write without read.

Yes, on x86. Is it the same for arm64?

Yes

One less thing to worry about then. Will make some tests for it anyway eventually.
