Modified files:
sys/kern kern_kse.c kern_thread.c
sys/sys proc.h
Log:
Actually, KSE kernel bits locking is broken and can lead likely to
dangerous races.
Fix this problems adding correct locking for the members of 'struct
kse_upcall' and other struct proc/struct thread related members.
For the moment, just leave ku_mflag and ku_flags "lazy" locked.
While here, cleanup the code removing the function kse_GC() (unused),
and merging upcall_link(), upcall_unlink(), upcall_stash() in their
respective callers (static functions, very short and only called in one
place).
