Today's -next fails to build an arm64 allnoconfig due to:
arm64-allnoconfig ../arch/arm64/mm/mmap.c:55:49: error: 'mmap_rnd_compat_bits' undeclared (first use in this function)
which was introduced by a combination of 8f62c06c279a3 (mm: mmap: add new /proc tunable for mmap_base ASLR) and 9411708692954 (arm64: mm: support ARCH_MMAP_RND_BITS). These add an unconditional use of mmap_rnd_compat_bits which is only defined in linux/mmap.h if HAVE_ARCH_MMAP_RND_COMPAT_BITS is selected but that is only enabled for arm64 if COMPAT is enabled. Either the select needs to be unconditional or the use needs to be.
