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

328175547f Revert "fix REQ-37: remap_one_page: remove to check page size" 
This reverts commit 6790126a23.

- reverted commit should remove a 'pgsize' check in remap_one_page()
  instead of a 'pgsize' check in pte_make_fileoff().
- In IA-32e, PTE format varies with page size. Therefore 'pgsize'
  parameter of pte_make_fileoff() is preferable.
