Hello, at https://reviews.freebsd.org/D18894 I put a review which main goal is to allow i386 kernels to use NX bits on capable hardware. In essence, single kernel now can operate using either PAE or non-PAE pagetables, the selection is done at the cold (very early boot, before paging is turned on) time. This together with earlier 4/4 work gives much more life into i386 kernels for whoever still needs them. Please review/test, see the differential review text for more explanation.
