I misread your email and thought this was still under arm-randconfig.
I checked the other architectures, and found that the same is missing on
ARC, so we should add both:
diff --git a/fs/Kconfig b/fs/Kconfig
index ec35851e5b71..a24d496787d6 100644
@@ -36,7 +36,7 @@ source "fs/nilfs2/Kconfig"
bool "Direct Access (DAX) support"
depends on MMU
- depends on !(ARM || MIPS || SPARC)
+ depends on !(ARC || ARM || MIPS || SH || SPARC)
Direct Access (DAX) can be used on memory-backed block devices.
If the block device supports DAX and the filesystem supports DAX,
It's also not implemented on c6x and blackfin, but both of them have
MMU=n, so they are already excluded.

Ah, right. I was looking at linux-next, which has the fix, so I did not
see the problem at first.
