Re: BUG with proposed fix Re: [uml-devel] Can't compile under vanilla 2.6.11

[Ian McDonald <imcdnzl@gmail.com>]

The other problem with not linking va_copy has been resolved by
changing to __va_copy in skas/uaccess.c. This seems to be a known
problem with older compilers and there is a patch out there but not in
2.6.11 or by the looks of it 2.6.12 rc1 by my reading of the log (nor
for one for my previous e-mail)
