This version has been tested on the sort multithreaded application
for TSAR_IOB architectures ranging from 1 to 8 clusters.
It fixes three bigs bugs:
1) the dev_ioc device API has been modified: the dev_ioc_sync_read()
and dev_ioc_sync_write() function use now extended pointers on the
kernel buffer to access a mapper stored in any cluster.
2) the hal_uspace API has been modified: the hal_copy_to_uspace()
and hal_copy_from_uspace() functions use now a (cxy,ptr) couple
to identify the target buffer (equivalent to an extended pointer.
3) an implementation bug has been fixed in the assembly code contained
in the hal_copy_to_uspace() and hal_copy_from_uspace() functions.
