error in the function hypercall_memfree(), where the wrong arena was being
passed to kmem_free().
Introduce a per-page flag, VPO_KMEM_EXEC, to mark physical pages that are
mapped in kmem with execute permissions. Use this flag to determine which
arena the kmem virtual addresses are returned to.
Eliminate UMA_SLAB_KRWX. The introduction of VPO_KMEM_EXEC makes it
redundant.
Update the nearby comment for UMA_SLAB_KERNEL.

sys/dev: further adoption of SPDX licensing ID tags.2017-11-27T14:52:40ZPedro F. Giffunipfg@FreeBSD.org2017-11-27T14:52:40Zurn:sha1:718cf2ccb9956613756ab15d7a0e28f2c8e91cab
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.

Makes things easier to read, plus architectures may set NULL to something
different than zero.

sys: use our roundup2/rounddown2() macros when param.h is available.2016-04-21T19:57:40ZPedro F. Giffunipfg@FreeBSD.org2016-04-21T19:57:40Zurn:sha1:d9c9c81c083a76a65c6cacf8fcbc0511e2ffa489
rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.
This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.
dev/agp: use our nitems() macro when it is avaliable through param.h.2016-04-19T23:31:35ZPedro F. Giffunipfg@FreeBSD.org2016-04-19T23:31:35Zurn:sha1:4ec642f1d61bbab5998f7b19281396ee925f82f0
Consistently capitalize the macros used in the driver.
No functional change.
agp: Do not attach to Intel GEN6+2016-03-12T09:44:23ZJean-Sébastien Pédrondumbbell@FreeBSD.org2016-03-12T09:44:23Zurn:sha1:85a60a7756050c046aa86ae3dc7a10cbd0145933
The i915 video driver doesn't depend on agp(4) anymore for Sandybridge
and later GPUs. Therefore, there is no need to attach agp(4) to those
devices.
While here, fix `agp_i965_res_spec` to include the aperture base for
GEN4 and GEN5.
