Today, I got this from the x86_64 allmodconfig build after merging the hid tree:

x86_64-linux-gnu-ld: include/config/acpi.h: file not recognized: file truncated
make[4]: *** [/home/sfr/next/next/scripts/Makefile.build:492: drivers/hid/i2c-hid/i2c-hid.o] Error 1
make[3]: *** [/home/sfr/next/next/scripts/Makefile.build:520: drivers/hid/i2c-hid] Error 2
make[2]: *** [/home/sfr/next/next/scripts/Makefile.build:520: drivers/hid] Error 2
make[1]: *** [/home/sfr/next/next/Makefile:1057: drivers] Error 2
make: *** [Makefile:152: sub-make] Error 2
