Thanks for your patch, which is now commit f2edd118d02dd114
("page_alloc: use vmalloc_huge for large system hash") upstream
(and which hasn't been in linux-next before).
As reported by noreply@xxxxxxxxxxxxxx, this is breaking e.g.
m68k/m5272c3_defconfig with:
page_alloc.c:(.init.text+0x13de): undefined reference to `vmalloc_huge'
vmalloc_huge() is provided by mm/vmalloc.c, which is not
compiled if CONFIG_MMU=n.
Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.
