hwpmc: Add EXTERROR diagnostics to the hwpmc syscall path

2026-07-21T17:14:39Z

Annotate validation failures in the PMC syscall handlers (allocate, attach, read/write) with EXTERROR(), so pmc(3) callers see which precondition failed, not a bare errno. Register HWPMC_MOD in exterr_cat.h and the generated filenames.h.

libproc: link against libctf if MK_CTF != no instead of MK_CDDL != no

2026-07-16T21:56:29Z

Logic prior to this change would incorrectly try linking when MK_CDDL != no, instead of MK_CTF != no, which could result in the library and the tests being broken if/when MK_CTF == no and MK_CDDL != no (an uncommon, but possible combination with today's build knobs). This change updates the conditional to correctly track the value of MK_CTF, which in turn is properly toggled to no if/when MK_CDDL == no as it's a dependent build knob. This [niche] build bug has been present in FreeBSD since 2014. MFC after: 1 week
