34a995d290 perfctr_stop: add flags to no 'disable_intens'

function, duplicating a lot of code - add a flag to existing function
instead.

A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

3e3ccf377c compiler.h: add READ_ONCE/WRITE_ONCE macro 
These macros are needed to make sure the compiler does not optimize away
atomic constructs such as "while (!READ_ONCE(foo))" loops that do not
modify foo within the loop

Also move the barrier() define where it belongs while we are here, it is
needed for READ_ONCE/WRITE_ONCE and including ihk/cpu.h here causes
include loops
