* sys: Automated cleanup of cdefs and other formattingWarner Losh2023-11-271-1/+0
| | | | | | | | | | | | | | | | Apply the following automated changes to try to eliminate no-longer-needed sys/cdefs.h includes as well as now-empty blank lines in a row. Remove /^#if.*\n#endif.*\n#include\s+<sys/cdefs.h>.*\n/ Remove /\n+#include\s+<sys/cdefs.h>.*\n+#if.*\n#endif.*\n+/ Remove /\n+#if.*\n#endif.*\n+/ Remove /^#if.*\n#endif.*\n/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/types.h>/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/param.h>/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/capsicum.h>/ Sponsored by: Netflix
* sccs: Manual changesWarner Losh2023-11-271-8/+0
| | | | | | | | | | | | | | | For the uncommon items: Go through the tree and remove sccs tags that didn't fit any nice pattern. If in the neighborhood, other SCM tags were removed when they were detritis of long-ago CVS somehow in the early mists of the project. Some adjacent copyrights stringswere removed (they duplicated the copyright notices in the file). This also removed non-standard formations of omission of SCCS tags (usually by adding an extra #if 0 somewhere. After this commit, a number of strings tagged with the 'what' @(#) prefix remain, but they are primarily copyright notices. Sponsored by: Netflix
* sys: Remove $FreeBSD$: one-line .c patternWarner Losh2023-08-168-15/+0

* spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSDWarner Losh2023-05-122-2/+2
| | | | | | | | | The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix
* arm: Remove unused ffs.SWarner Losh2022-10-201-58/+0
| | | | | | | | We've not used ffs.S since we retired armv[45] support. Remove it from the tree. Suggested by: andrew in D37069 Sponsored by: Netflix

* sys/kern: adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-272-1/+5
| | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=326271
* sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326023

* Fix unwind-info errors in our hand-written arm assembler code.Ian Lepore2014-08-011-10/+10
| | | | | | | | | | | | | | | | | | | | | | We have functions nested within functions, and places where we start a function then never end it, we just jump to the middle of something else. We tried to express this with nested ENTRY()/END() macros (which result in .fnstart and .fnend directives), but it turns out there's no way to express that nesting in ARM EHABI unwind info, and newer tools treat multiple .fnstart directives without an intervening .fnend as an error. These changes introduce two new macros, EENTRY() and EEND(). EENTRY() creates a global label you can call/jump to just like ENTRY(), but it doesn't emit a .fnstart. EEND() is a no-op that just documents the conceptual endpoint that matches up with the same-named EENTRY(). This is based on patches submitted by Stepan Dyatkovskiy, but I made some changes and added the EEND() stuff, so blame any problems on me.

* Fix ixp425 boot2 with ARM EABI:Andrew Turner2013-09-291-0/+4
| | | | | | | | | | | - libkern is missing __aeabi_llsl, implement this by calling __ashldi3. - Because of how the asm entry macros are defined the boot2 code requires the unwind symbols to exist, include them in boot2. Approved by: re (marius) Notes: svn path=/head/; revision=255939
