The following patch fixes the compile breakage. For my own knowledge, why did this break in
this particular way?

Subject: [PATCH] um: Use asm-generic/scatterlist.h

commit ff35bd54456e18878c361a8a2deeb41c9688458f
(lib/scatterlist: make ARCH_HAS_SG_CHAIN an actual Kconfig) changed
some architectures to use the generic scatterlist.h but this broke
um:

In file included from init/main.c:75:0:
include/linux/blkdev.h:25:29: fatal error: asm/scatterlist.h:
No such file or directory

Make um use the generic scatterlist.h as well
