Not giving any argument means that any argument is OK,

aa7cb970c4 ihk_os_getrusage(): Compile LWK-specific results in mcctrl 
1. User asks mcctrl for the result via ihk_os_getrusage() with passing void *
2. mcctrl compiles the results and passes them to the user
3. User interprets it by using the type defined in the LWK-specific header

  that is, change parameter 'virt' from       'void *'
                                     to 'const void *'

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.
