raid6.c was failing to build for Goffredo and me due to __attribute_const__ being undefined. Define it in kerncompat.h and include that; this also makes sure BITS_PER_LONG is defined for raid6.c, prior to this it was not defined, at least in my build. Finally, redefine BITS_PER_LONG in a way that it can be tested in the preprocessor macro.
