Fixed, but we may want the patch on 4.0 too.

Yes, it does the drill: 
I back port this patch against debian gcc-4.1 stock sources (gcc version 4.1.2
20060604 (prerelease) (Debian 4.1.1-2)) and got this excellent improvement of
the real case (kernel parisc linux page_alloc.c)
# time sh ../TstPageAlloc
+ hppa64-linux-gnu-gcc-4.1 -Wp,-MD,mm/.page_alloc.o.d -nostdinc -isystem

with the debian stock 64bit xcompiler:

sys 0m2.520s

with patch applied:

Thanks a lot,
