Author: marius Date: Tue Jul 5 20:05:06 2011 New Revision: 223806 URL: http://svn.freebsd.org/changeset/base/223806 Log: Remove the IDR_CHEETAH_MAX_BN_PAIRS limit from cheetah_ipi_selected(). This is just a simple approach. For reasons unknown OpenSolaris uses a more sophisticated one involving IPIing the remaining CPUs in reverse order after the first batch of 32.
