Current egcs, binutils and kernel (fwd)

I looked at the code in "misc.S" and it appears to me [by cursory glance]
that it already is "__lshrdi3" - i.e. the code that is there is doing a
logical shift and not an arithmetic one!
It seems to me that you could just add "__lshrdi3" as an alternate entry
I need to investigate the existing code and see if maybe my impression
is just "day's end..."
