Sounds good. Except you say "Al Viro's signal handling fixes" without
giving any context, so I have no idea which patches you are referring
to.
Regardless, if there's some fixes queue that also removes set_fs()
from m68k, I'm willing to take it for 5.15 just to have another
architecture down and done with.
And even if the set_fs() patches might still be under discussion, the
format errors have been going on for some time, so the signal fixes -
wherever they are - seem to be no-brainers if they fix those.
