dtrace: Avoid including dtrace_isa.c directly into dtrace.c

2024-08-08T15:53:50+00:00

This was done in the original DTrace import, presumably because that
made it a bit easier to handle includes.  However, this can cause
dtrace_getpcstack() to be inlined into dtrace_probe(), resulting in a
missing frame in stack traces since dtrace_getpcstack() takes care to
bump "aframes" to account for its own stack frame.

To avoid this, compile dtrace_isa.c separately on all platforms.  Add
requisite includes.

2023-05-12T16:44:03+00:00

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.

dtrace: expose dtrace_instr_size() to userland and implement it for riscv

2023-04-20T17:35:57+00:00

dtrace_instr_size() is needed by the forthcoming RISC-V port of kinst,
as well as by libdtrace in D38825 for both amd64 and RISC-V.
