Remove all the 'entry' and 'return' probes; they clutter up the source
and are redundant to FBT.

linux: add sysctl compat.linux.use_emul_path2020-08-18T22:04:22ZMateusz Guzikmjg@FreeBSD.org2020-08-18T22:04:22Zurn:sha1:a125ed50a6c82329997ecf4df593056a8a616cbe
This is a step towards facilitating jails with only Linux binaries.
Supporting emul_path adds path lookups which are completely spurious
if the binary at hand runs in a Linux-based root directory.
It defaults to on (== current behavior).

sys/compat: further adoption of SPDX licensing ID tags.2017-11-27T15:13:23ZPedro F. Giffunipfg@FreeBSD.org2017-11-27T15:13:23Zurn:sha1:7f2d13d60721803155950276e0282fcd1e6bacc3
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.
Where possible we will use M_LINUX malloc(9) type.2015-05-24T16:14:41ZDmitry Chagindchagin@FreeBSD.org2015-05-24T16:14:41Zurn:sha1:e0d3ea8c655d56fd364dba6d91dec8d3e443cb80
Move M_FUTEX defines to the linux_common.ko.

The goal here is to provide one place altering process credentials.
This eases debugging and opens up posibilities to do additional work when such
an action is performed.

have both kern_open() and kern_openat(); change the callers to use
kern_openat().
This removes one (sometimes two) levels of indirection and
consolidates arguments checks.

- For kernel compiled only with KDTRACE_HOOKS and not any lock debugging2013-11-25T07:38:45ZAttilio Raoattilio@FreeBSD.org2013-11-25T07:38:45Zurn:sha1:54366c0bd7d0ea904fb9ab32460c66d57684a7cb
option, unbreak the lock tracing release semantic by embedding
calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined
version of the releasing functions for mutex, rwlock and sxlock.
Failing to do so skips the lockstat_probe_func invokation for
unlocking.
- As part of the LOCKSTAT support is inlined in mutex operation, for
kernel compiled without lock debugging options, potentially every
consumer must be compiled including opt_kdtrace.h.
Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the
dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES
is linked there and it is only used as a compile-time stub [0].
[0] immediately shows some new bug as DTRACE-derived support for debug
in sfxge is broken and it was never really tested. As it was not
including correctly opt_kdtrace.h before it was never enabled so it
was kept broken for a while. Fix this by using a protection stub,
leaving sfxge driver authors the responsibility for fixing it
appropriately [1].
