Author: jhibbits Date: Tue Mar 1 02:59:06 2016 New Revision: 296250 URL: https://svnweb.freebsd.org/changeset/base/296250 Log: Correct the memory rman ranges to be to BUS_SPACE_MAXADDR Summary: As part of the migration of rman_res_t to be typed to uintmax_t, memory ranges must be clamped appropriately for the bus, to prevent completely bogus addresses from being used. This is extracted from D4544.
