spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD2023-07-25T15:13:49ZWarner Loshimp@FreeBSD.org2023-05-10T15:40:58Zurn:sha1:caa41f641755c935b036e17440a3b49329c904ed
The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

x86: Add a NT_X86_SEGBASES register set.2022-05-13T16:45:19ZJohn Baldwinjhb@FreeBSD.org2022-03-24T18:36:19Zurn:sha1:382ffc87860cd09f9350179e59bdf88f07b55631
This register set contains the values of the fsbase and gsbase
registers. Note that these registers can already be controlled
individually via ptrace(2) via MD operations, so the main reason for
adding this is to include these register values in core dumps. In
particular, this will enable looking up the value of TLS variables
from core dumps in gdb.
The value of NT_X86_SEGBASES was chosen to match the value of
NT_386_TLS on Linux. The notes serve similar purposes, but FreeBSD
will never dump a note equivalent to NT_386_TLS (which dumps a single
segment descriptor rather than a pair of addresses) and picking a
currently-unused value in the NT_X86_* range could result in a future
conflict.

Create sys/reg.h for the common code previously in machine/reg.h2022-05-12T22:12:59ZAndrew Turnerandrew@FreeBSD.org2021-08-27T09:38:40Zurn:sha1:e5e2c7ffa0f7d9ba0874b95924f4d977b116f45b
Move the common kernel function signatures from machine/reg.h to a new
sys/reg.h. This is in preperation for adding PT_GETREGSET to ptrace(2).

Rather than fetching the ps_strings address directly from a process'
sysentvec, use this macro. With stack address randomization the
ps_strings address is no longer fixed.
