Move most of the contents of opt_compat.h to opt_global.h.

2018-04-06T17:35:35Z

opt_compat.h is mentioned in nearly 180 files. In-progress network driver compabibility improvements may add over 100 more so this is closer to "just about everywhere" than "only some files" per the guidance in sys/conf/options. Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h is created on all architectures. Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the set of compiled files.

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

2017-11-27T14:52:40Z

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.

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.

Revert r317446 and bring back cy(4).

Remove the cy(4) driver for Cyclades serial adapters.

2017-04-26T18:23:09Z

This driver has been disconnected from the build since the new tty layer was introduced in 8.0 and was never updated for new tty.

sys/dev: extend use of the howmany() macro when available.

2016-04-26T15:03:15Z

We have a howmany() macro in the header that is convenient to re-use as it makes things easier to read.

Fix the build.

Replace several bus_alloc_resource() calls using default arguments with bus_alloc_resource_any()

2016-02-19T03:37:56Z

Since these calls only use default arguments, bus_alloc_resource_any() is the right call. Differential Revision: https://reviews.freebsd.org/D5306

Fixed a panic in the probe. The memory resource was accessed after

releasing it. This seems to have worked until a few days ago, but now the memory is unmapped.
