All the linux-next builds for mips are failing, which I tracked down to this.
Applying the above update doesn't help. What is happening is that MIPS
gets KBUILD_CPPFLAGS double-quoted, and then you get:
+ mips-wrs-linux-gnu-nm -n .tmp_vmlinux1
+ scripts/kallsyms
+ mips-wrs-linux-gnu-gcc -D__ASSEMBLY__ <..snip..> -D__KERNEL__
'-D"VMLINUX_LOAD_ADDRESS=0xffffffff81100000"' '-D"DATAOFFSET=0"' -c -o
.tmp_kallsyms1.o -x assembler-with-cpp -
<command-line>:0: error: macro names must be identifiers
<command-line>:0: error: macro names must be identifiers
make[1]: *** [vmlinux] Error 1
Note the '-D"VMLINUX_LOAD_ADDRESS=0xffffffff81100000"' '-D"DATAOFFSET=0"'
part -- that is what triggers the two above errors.
