Do pass removing some write-only variables from the kernel.

This reduces noise when kernel is compiled by newer GCC versions, such as one used by external toolchain ports.

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.

Make this compile with DEVICE_POLLING set.

smc_poll had the wrong prototype. It returns 0 as it does not check anything but submits a taskqueue. Reviewed by: benno MFC after: 2 weeks

Remove taskqueue_enqueue_fast().

2016-03-01T17:47:32Z

taskqueue_enqueue() was changed to support both fast and non-fast taskqueues 10 years ago in r154167. It has been a compat shim ever since. It's time for the compat shim to go. Submitted by: Howard Su Reviewed by: sephe Differential Revision: https://reviews.freebsd.org/D5131

Migrate many bus_alloc_resource() calls to bus_alloc_resource_anywhere().

In order to reduce use of M_EXT outside of the mbuf allocator and

2015-01-06T12:59:37Z

socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.
