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

a6488adcc1 change parameter type of ihk_mc_pt_virt_to_phys()
- add type qualifier 'const' to virtual address parameter.
  that is, change parameter 'virt' from       'void *'
                                     to 'const void *'

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).

bbbc6e1570 add shared mapped file (in progress)
implemented:
- Pages can be shared between maps.
- A change made to a map is written to the file, at munmap().

not yet implemented:
- VM operation during page IO execution.
  Because page IO is executed with VM's lock.
- Page IO, which does not change a file size with any case.
  When munmap() races with truncate(), the file size may be changed
  illegally.
