* libkern: Add libcalls for ffs and __ffsdi2John Baldwin2026-01-311-0/+47
| | | | | | | | | | | | These are needed when compiling a RISC-V kernel with GCC which does not inline __builtin_ffs*. The __ffsdi2 is adapated from the previous ffsl.c. This partially reverts commit f4db342d44198973c1c7b9005d0c5683a582707e. Reviewed by: mhorne Differential Revision: https://reviews.freebsd.org/D54967
* libkern: remove old ffs/fls routinesMitchell Horne2023-07-061-50/+0
| | | | | | | | | These are poorly optimized (linear search), and we now prefer the compiler-provided routines on all platforms. These files can be removed. Reviewed by: emaste, dougm Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D40699
* 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
