arm/arm64: KVM: Enforce HYP read-only mapping of the kernel's rodata section In order to be able to use C code in HYP, we're now mapping the kernel's rodata in HYP. It works absolutely fine, except that we're mapping it RWX, which is not what it should be. Add a new HYP_PAGE_RO protection, and pass it as the protection flags when mapping the rodata section.
