kldxref: Reduce divergence between per-architecture files Note that relbase is always 0 for DSOs so its omission for __KLD_SHARED architectures was not a bug in practice. Whilst here, also parenthesise the dest offset for where to avoid transiently creating an out-of-bounds pointer, which is UB (though even on CHERI architectures, where capability bounds compression can result in that creating invalid capabilities that will trap on dereference, optimisation will reassociate to the correct form in practice and thus work just fine).

kldxref: Make use of libelf to be a portable cross tool This allows kldxref to operate on kernel objects from any architecture, not just the native architecture. In particular, this will permit generating linker.hints files as part of a cross-arch release build. - elf.c is a new file that includes various wrappers around libelf including routines to read ELF data structures such as program and section headers and ELF relocations into the "generic" forms described in <gelf.h>. This file also provides routines for converting a linker set into an array of addresses (GElf_Addr) as well as reading architecture-specific mod_* structures and converting them into "generic" Gmod_* forms where pointers are replaced with addresses. - The various architecture-specific reloc handlers now use GElf_* types for most values (including GElf_Rel and GElf_Rela for relocation structures) and use routines from <sys/endian.h> to read and write target values. A new linker set matches reloc handlers to specific ELF (class, encoding, machine) tuples. - The bits of kldxref.c that write out linker.hints now use the encoding (ELFDATA2[LM]SB) of the first file encountered in a directory to set the endianness of the output file. Input files with a different architecture in the same directory are skipped with a warning. In addition, the initial version record for the file must be deferred until the first record is finished since the architecture of the output file is not known until then. - Various places that used 'sizeof(void *)' throughout now use 'elf_pointer_size()' to determine the size of a pointer in the target architecture.

Fix kldxref on PowerPC64 When using kldxref on kernel modules built with clang8 + lld8, kldxref would be unable to find the modules metadata information, because PowerPC64 was using the ef_nop.c implementation of ef_reloc(). When GNU LD was used, it was also relocating the metadata section of the .ko file. LLD does not do this, but only generate dynamic relocations for it. With minor changes, ef_powerpc.c can now work for PowerPC64 too. Reviewed by: emaste Differential Revision: https://reviews.freebsd.org/D19370

various: general adoption of SPDX licensing ID tags. 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. No functional change intended.

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

In particular this means: o Remove Elf64_Quarter, o Redefine Elf64_Half to be 16-bit, o Redefine Elf64_Word to be 32-bit, o Add Elf64_Xword and Elf64_Sxword for 64-bit entities, o Use Elf_Size in MI code to abstract the difference between Elf32_Word and Elf64_Word. o Add Elf_Ssize as the signed counterpart of Elf_Size.
