Author: jhibbits Date: Fri Jan 26 00:56:09 2018 New Revision: 328424 URL: https://svnweb.freebsd.org/changeset/base/328424 Log: Minimal change to build linuxkpi on architectures with physical addresses larger than virtual Summary: Some architectures have physical/bus addresses that are much larger than virtual addresses. This change just quiets a warning, as DMAP is not used on those architectures, and on 64-bit platforms uintptr_t is the same size as vm_paddr_t and void *.
