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.

a2548f5421 Revert "fix REQ-42" 
This reverts commit 4a0682bbc1.

The reverted commit appears to be wrong, for example:
- arch_range_check()'s arguments and parameters are mismatch.
- arch_range_check() implementation is not checking range.
