LGTM. Indeed only these 3 archs don't TCONF.

Out of curiosity, where is the support defined in kernel?
"if (clone_flags & CLONE_SETTLS)" is in many archs:

$ git grep CLONE_SETTLS
...
arch/loongarch/kernel/process.c:220:    if (clone_flags & CLONE_SETTLS)
arch/m68k/kernel/process.c:179: if (clone_flags & CLONE_SETTLS)
arch/microblaze/kernel/process.c:110:   if (clone_flags & CLONE_SETTLS)
arch/mips/kernel/process.c:171: if (clone_flags & CLONE_SETTLS)
arch/nios2/kernel/process.c:143:        if (clone_flags & CLONE_SETTLS)
arch/openrisc/kernel/process.c:199:              * For CLONE_SETTLS set "tp" (r10) to the TLS pointer.
arch/openrisc/kernel/process.c:201:             if (clone_flags & CLONE_SETTLS)
arch/parisc/kernel/process.c:251:               if (clone_flags & CLONE_SETTLS)
arch/powerpc/kernel/process.c:1819:                     if (clone_flags & CLONE_SETTLS) {

Kind regards,
Petr
