        src/sys/arch/arm/arm32: cpu.c pmap.c
        src/sys/arch/arm/include: cpu.h types.h
        src/sys/arch/arm/include/arm32: param.h pmap.h pte.h
        src/sys/kern: init_sysctl.c

Log Message:
Use 4K pages on ARM_MMU_EXTENDED platforms (all armv[67] except RPI) by
creating a new pool l1ttpl for the userland L1 translation table which
needs to be 8KB and 8KB aligned.

Limit the pool to maxproc and add hooks to allow the sysctl changing of
maxproc to adjust the pool.

This comes at a 5% performance penalty for build.sh -j8 kernel on a
Tegra TK1.
