Modified Files: src/sys/arch/x86/x86: pmap.c Log Message: When a user pmap is created, it is populated with the higher kernel slots, which become accessible upon kernel entry (syscall, cpu switch, or whatever). Put the NOX bit in the user recursive slot, so the whole tree does not appear as executable in kernel mode. This is already what is done in the kernel pmap.
