It looks like Zach Brown's patch pr_debug-check-pr_debug-arguments

The arm build fails with the following message:
CC arch/arm/vfp/vfpsingle.o
arch/arm/vfp/vfpsingle.c: In function `__vfp_single_normaliseround':
arch/arm/vfp/vfpsingle.c:201: error: `func' undeclared (first use in
this function)
arch/arm/vfp/vfpsingle.c:201: error: (Each undeclared identifier is
reported only once
arch/arm/vfp/vfpsingle.c:201: error: for each function it appears in.)
make[1]: *** [arch/arm/vfp/vfpsingle.o] Error 1
make: *** [arch/arm/vfp] Error 2

The following patch fixes the issue by using func only when DEBUG is
