Author: kib Date: Tue Apr 20 08:19:43 2010 New Revision: 206890 URL: http://svn.freebsd.org/changeset/base/206890 Log: MFC r206553: Change printf() calls to uprintf() for sigreturn() and trap() complaints about inacessible or wrong mcontext, and for dreaded "kernel trap with interrupts disabled" situation. The later is changed when trap is generated from user mode (shall never be ?). Normalize the messages to include both pid and thread name.
