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.
