Author: jkim Date: Mon Jun 3 16:46:37 2013 New Revision: 251307 URL: http://svnweb.freebsd.org/changeset/base/251307 Log: MFC: r251186 Fix a long standing logic bug introduced in r167814. The code was added to get RSDP from loader(8) hint via kenv(2) but the bug nullified the new code and we always fell back to the previous method, i. e., sysctlbyname(3).
