linux-next: build failure after merge of the akpm-current tree

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm64 allnoconfig and others) failed like this:

arch/arm64/mm/mmap.c:54:1: error: unknown type name 'ifdef' arch/arm64/mm/mmap.c:55:2: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'if' arch/arm64/mm/mmap.c:57:2: error: 'else' without a previous 'if' arch/arm64/mm/mmap.c:58:2: error: #endif without #if

Caused by commit

2e4614190421 ("arm64-mm-support-arch_mmap_rnd_bits-v4")

An obvious typo :-(

I will add the missing '#' tomorrow if it si not fixed by then.
