Sorry, yes this is OK.
I wanted to review this against the problem that there are at least 3
different FPA-flavoured interfaces in linux: NWFPE, NWFPE with extended
precision and genuine FPA11, and that each of these has a slightly
different format for the values returned via the ptrace interface (yes,
this is really a bug in ARM linux, but it ain't going to get fixed
now...). However, I'm now happy your patch doesn't make things either
better or worse in this regard.
R.
