Incidentally, calling that from ptraced process on alpha leads to
the same headache for tracer. _If_ we leave it around, this is
another candidate for "hit yourself with that special signal" -
both alpha and m68k have that syscall, and IMO adding an asm
wrapper for that one is over the top.
Said that, we really ought to bury that thing:

[PATCH] deprecate use of bdflush()
Patch from Robert Love <rml@xxxxxxxxx>
We can never get rid of it if we do not deprecate it - so do so and
print a stern warning to those who still run bdflush daemons.
Deprecated for 18.5 years by now - I seriously suspect that we have
some contributors younger than that...
