SVN rev 219187 on 2011-03-02 19:09:49Z by jkim
MFC: r216634, r216673
Improve PCB flags handling and make it more robust. Add two new functions
for manipulating pcb_flags. These inline functions are very similar to
atomic_set_int(9) and atomic_clear_int(9) but without unnecessary LOCK
prefix for SMP. Add comments about the rationale. Use these functions
wherever possible. Although there are some places where it is not strictly
necessary (e.g., a PCB is copied to create a new PCB), it is done across
the board for sake of consistency. Turn pcb_full_iret into a PCB flag as
it is safe now. Move rarely used fields before pcb_flags and reduce size
of pcb_flags to four bytes. Fix some style(9) nits in pcb.h while I am in
the neighborhood.
