Re: [uml-devel] uml-patch-2.4.24-3

["roland" <for_spam@gmx.de>]

hi jeff, 
compiling a 2.4.26 with uml-patch-2.4.24-3 still seems to have
the __cmpxchg issue.
see:
http://article.gmane.org/gmane.linux.uml.user/3806

i attached the mentioned patch and after that,  it compiles cleanly
for me.

regards
roland
