hm, had a build failure:

arch/x86/mm/mmap.c: In function 'ia32_pick_mmap_layout':
arch/x86/mm/mmap.c:49: error: 'ADDR_COMPAT_LAYOUT' undeclared (first use in this function)
arch/x86/mm/mmap.c:49: error: (Each undeclared identifier is reported only once
arch/x86/mm/mmap.c:49: error: for each function it appears in.)

Config attached.
