asm-generic changes for 4.6

Browse Source 
There are only three patches this time, most other changes to
 files in include/asm-generic tend to go through the tree of whoever
 depends on the change.
 
 Two patches are cleanups for stuff that is no longer needed,
 the main change is to adapt the generic version of BUG_ON()
 for CONFIG_BUG=n to make it behave consistently with BUG().
 
 This avoids undefined behavior along with a number of warnings
 about that undefined behavior in randconfig builds when
 we keep going on after hitting a BUG_ON().
