[SSI] openssi/kernel/include/cluster/ssi/mosixll mosixtask.h, 1.8, 1.9 routines.h, 1.7, 1.8

Update of /cvsroot/ssic-linux/openssi/kernel/include/cluster/ssi/mosixll
In directory fdv4jf1.ch3.sourceforge.com:/tmp/cvs-serv10005/kernel/include/cluster/ssi/mosixll

Modified Files:
      Tag: OPENSSI-FC
	mosixtask.h routines.h 
Log Message:
MOSIX:
- Fix race over elements in mosix_task struct. Use task_lock() to protect mosix_task->dctime, pages_i_bring, etc.
- Code clean up: choose(), consider(), mosix_calc_load().
- Fix release_migrations() using wrong lock for mosix_task->load.
- Remove unused pagetime, migpages in struct mosix_task.
- run_over_dirty_pages() to hold down_read(&mmap_sem) to avoid possible race. (#ifdef SSI_BALANCE_MEMORY)

VPROC:
- Use BKL to protect tty_old_pgrp in VProc context. (#ifdef PPROC_SETCTTY_SIGLOCK)
