[PATCHv5 0/7] Better page protections for arm64

[lauraa@codeaurora.org (Laura Abbott)]

Hi,

This is v5 of the series to add stricter page protections for arm64.
The goal is to have text be RO/NX and everything else be RW/NX.
I finally got my hands on a Juno board so I was able to do more
testing with both 4K and 64K pages although I still haven't tested
with EFI. This is based off of 3.18-rc5.

Thanks,
Laura
