Improve make_page_readonly and make_page_writable:
 1. Use update_va_mapping where possible (much faster)
 2. If that fails, fall back to explicit pte update rather
    than using writable pagetables (very slow for singleton
    updates)

Also many x86/64 cleanups and fix to handle vmalloc space
correctly.
