Modified files:
sys/kern kern_sig.c
Log:
- Proc locking. Most of signal handling is now MP safe and doesn't require
Giant. The only exception is the CANSIGNAL() macro. Unlocking the proc
lock around sendsig() in trapsignal() is also questionable. Note that
the functions sigexit(), psignal(), and issignal() must be called with
the proc lock of the process in question held. postsig() and
trapsignal() should not be called with the proc lock held, but they
also do not require Giant anymore either.
- Remove spl's that are now no longer needed as they are fully replaced.
