Author: marius Date: Sun Oct 17 11:51:59 2010 New Revision: 213953 URL: http://svn.freebsd.org/changeset/base/213953 Log: MFC: r213873 Explicitly lower the PIL to 0 as part of enabling interrupts, similar to what is done on other platforms. Unlike as with the sched_throw(NULL) called on BSPs during their startup apparently there's nothing which will reliably lower it on APs. I'm unsure why this only came up on V215 though, breaking these with r207248. My best guess is that these are the only supported ones so far fast enough to lose some race.
