3e00189de0 kprintf: fix checking if interrupt is disabled

a9973e913d uti: futex call function in mcctrl 
Previously, futex code of McKerenl was called by mccontrol,
but there ware some problems with this method.
(Mainly, location of McKernel image on memory)

Call futex code in mcctrl instead of the one in McKernel image,
giving the following benefits:
1. Not relying on shared kernel virtual address space with Linux any more
2. The cpu id store / retrieve is not needed and resulting in the code

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

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).
