Author: kib Date: Wed May 27 21:44:26 2020 New Revision: 361563 URL: https://svnweb.freebsd.org/changeset/base/361563 Log: Simplify the condition to enable superpage mappings in vm_fault_soft_fast(). The list of arches list there matches the list of arches where default VM_NRESERVLEVEL > 0. Before sparc64 removal, that was the only arch that defined VM_NRESERVLEVEL > 0 to help with cache coloring, but did not implemented superpages. Now it can be simplified.
