Subject: [ltt-dev] [PATCH 07/12] use uatomic_generic.h for common fallback implementations
Date: Fri, 19 Feb 2010 20:22:49 +0100 [thread overview]
Message-ID: <1266607374-1107-8-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1266607374-1107-1-git-send-email-pbonzini@redhat.com>
And now, really remove the code for S390/SPARC, using the fallback
implementation of uatomic_generic.h
Signed-off-by: Paolo Bonzini <pbonzini at redhat.com>
