fcbaa9726c correct the syscall return type 
Long size syscall return values such as shmat()'s and lseek()'s are
broken, because lower 32 bits are only returned.

f0a52d4519 implement mmap(MAP_POPULATE) 
populate_process_memory() function is not efficient,
because whether every small page is present is checked.

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.

bdc02bb687 refuse the write to a read-only memory 
It was able to change a read-only memory using a system call that
forwarded to host.

To fix this, when read-only mmap(), it places read-only vm_area in the
mcexec's space.
