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

this is not what is meant here.

1aac2c8e23 add CPU timer initialization (refs #402) 
There is no actual initialization in x86 now.
The initialization rely on hardware reset and Linux initialization.

a9bebf1e14 Make idle loop not miss a chance to schedule 
Prevents the case where McKernel misses one chance to schedule a
task when an interrupt occurs just after enabling interrupt and
just before executing "halt" in the idle loop (in kernel/process.c).
