arm64: Add CONFIG_DEBUG_SET_MODULE_RONX support In a similar fashion to other architecture, add the infrastructure and Kconfig to enable DEBUG_SET_MODULE_RONX support. When enabled, module ranges will be marked read-only/no-execute as appropriate.

ARM64: mm: HugeTLB support. Add huge page support to ARM64, different huge page sizes are supported depending on the size of normal pages: PAGE_SIZE is 4KB: 2MB - (pmds) these can be allocated at any time. 1024MB - (puds) usually allocated on bootup with the command line with something like: hugepagesz=1G hugepages=6 PAGE_SIZE is 64KB: 512MB - (pmds) usually allocated on bootup via command line.

arm64: add support to dump the kernel page tables In a similar manner to arm, it's useful to be able to dump the page tables to verify permissions and memory types. Add a debugfs file to check the page tables.

arm64: use fixmap region for permanent FDT mapping Currently, the FDT blob needs to be in the same 512 MB region as the kernel, so that it can be mapped into the kernel virtual memory space very early on using a minimal set of statically allocated translation tables. Now that we have early fixmap support, we can relax this restriction, by moving the permanent FDT mapping to the fixmap region instead. This way, the FDT blob may be anywhere in memory. This also moves the vetting of the FDT to mmu.c, since the early init code in head.S does not handle mapping of the FDT anymore. At the same time, fix up some comments in head.S that have gone stale.
