Hi Dave,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on tip/auto-latest]
[also build test WARNING on next-20180403]
[cannot apply to tip/x86/core v4.16]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Dave-Hansen/Use-global-pages-with-PTI/20180404-135611
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> arch/x86/mm/pti.c:286:1: sparse: symbol 'pti_clone_pmds' was not declared. Should it be static?
   arch/x86/mm/pti.c:439:6: sparse: symbol 'pti_set_kernel_image_nonglobal' was not declared. Should it be static?

Please review and possibly fold the followup patch.
