Message:

1) Fix a bug in the vfs_add_special_dentries() function:
The <.> and <..> dentries must not be created on IOC and on the mapper
for the VFS root directory.
2) Fix a bug in the hal_gpt_allocate_pt2 function, related to the
use of the TSAR_LOCKED attribute to avoid concurrent mapping of the PTD1.
