Flesh out the sparc64 port considerably. This contains: - mostly complete kernel pmap support, and tested but currently turned off userland pmap support - low level assembly language trap, context switching and support code - fully implemented atomic.h and supporting cpufunc.h - some support for kernel debugging with ddb - various header tweaks and filling out of machine dependent structures 2001-07-31 06:05:05 +00:00			`/*-`
sys/sparc64: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-11-27 15:10:39 +00:00			`* SPDX-License-Identifier: BSD-2-Clause-FreeBSD`
