spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD2023-05-12T16:44:03ZWarner Loshimp@FreeBSD.org2023-05-10T15:40:58Zurn:sha1:4d846d260e2b9a3d4d0a701462568268cbfe7a5b
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.

libc: further adoption of SPDX licensing ID tags.2017-11-25T17:12:48ZPedro F. Giffunipfg@FreeBSD.org2017-11-25T17:12:48Zurn:sha1:d915a14ef094c8dfc1a5aee70e135abfec01d0f1
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified 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.
Use struct vdso_timehands data to implement fast gettimeofday(2) and2012-06-22T07:13:30ZKonstantin Belousovkib@FreeBSD.org2012-06-22T07:13:30Zurn:sha1:869fd80fd449c2e3f8d7caa7ff4af71e904b5f08
clock_gettime(2) functions if supported. The speedup seen in
microbenchmarks is in range 4x-7x depending on the hardware.
Only amd64 and i386 architectures are supported. Libc uses rdtsc and
kernel data to calculate current time, if enabled by kernel.
Hopefully, this code is going to migrate into vdso in some future.
