What the check_exec() function really is trying to do is enforce certain bits in the pgprot that are required by the x86 architecture, but that callers might not be aware of (such as NX bit exclusion of the BIOS area for BIOS based PCI access; it's not uncommon to ioremap the BIOS region for various purposes and normally ioremap() memory has the NX bit set). This patch turns the check_exec() function into static_protections() which also is now used to make sure the kernel text area remains non-NX and that the .rodata section remains read-only. If the architecture ends up requiring more such mandatory prot settings for specific areas, this is now a reasonable place to add these.
