spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+00:00

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.

linux(4): Implement semtimedop syscalls.

2022-05-06T17:02:59+00:00

On i386 are two semtimedop. The old one is called via multiplexor and
uses 32-bit timespec, and new semtimedop_tim64, which is uses 64-bit
timespec.

linux(4): Retire linux_semop implementation.

2022-05-06T17:00:13+00:00

In i386 Linux semop called via ipc() multiplexor, so use kern_semop
directly from multiplexor.

Update syscall.master to 5.0.

2019-03-24T14:50:02+00:00

For 32-bit Linuxulator, ipc() syscall was historically
the entry point for the IPC API. Starting in Linux 4.18, direct
syscalls are provided for the IPC. Enable it.

MFC after:	1 month

Linux between 4.18 and 5.0 split IPC system calls.

2019-03-24T14:44:35+00:00

In preparation for doing this in the Linuxulator modify our linux_shmat()
to match actual Linux shmat() system call.

Rationalize license text on Linuxolator files

2018-03-23T14:39:34+00:00

Many licenses on Linuxolator files contained small variations from the
standard FreeBSD license text.  To avoid license proliferation switch to
the standard 2-Clause FreeBSD license for those files where I have
permission from each of the listed copyright holders.

Linuxolator whitespace cleanup

2018-02-05T17:29:12+00:00

A version of each of the MD files by necessity exists for each CPU
architecture supported by the Linuxolator.  Clean these up so that new
architectures do not inherit whitespace issues.

Clean up shared Linuxolator files while here.

sys/compat: further adoption of SPDX licensing ID tags.

2017-11-27T15:13:23+00:00

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.

x86_64 Linux do not use multiplexing on ipc system calls.

2015-05-24T15:44:41+00:00

Move struct ipc_perm definition to the MD path as it differs for 64 and
32 bit platform.
