Alexander Duyck 8a44971841 arch: Cleanup read_barrier_depends() and comments ... This patch is meant to cleanup the handling of read_barrier_depends and smp_read_barrier_depends. In multiple spots in the kernel headers read_barrier_depends is defined as "do {} while (0)", however we then go into the SMP vs non-SMP sections and have the SMP version reference read_barrier_depends, and the non-SMP define it as yet another empty do/while. With this commit I went through and cleaned out the duplicate definitions and reduced the number of definitions down to 2 per header. In addition I moved the 50 line comments for the macro from the x86 and mips headers that defined it as an empty do/while to those that were actually defining the macro, alpha and blackfin.
