Modified files:
sys/kern kern_sig.c
Log:
Unpessimized CURSIG(). The fast path through CURSIG() was broken in
the 128-bit sigset_t changes by moving conditionally (rarely) executed
code to the beginning where it is always executed, and since this code
now involves 3 128-bit operations, the pessimization was relatively
large. This change speeds up lmbench's pipe latency benchmark by
3.5%.
Fixed style bugs in CURSIG().
