Author: zbb Date: Thu Jan 2 11:24:04 2014 New Revision: 260189 URL: http://svnweb.freebsd.org/changeset/base/260189 Log: Revert r260165: Proper configuration of unmapped_buf_allowed should be used To avoid failures in bus_dmamap_sync() on ARM unmapped_buf_allowed should be set to 0. Hence, ARM-specific changes in AHCI should not be applied.
