From: Jan Beulich Date: Fri, 16 Mar 2012 10:35:06 +0000 (+0100) Subject: unmodified drivers: use upstream sync_bitops if available X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=256eea1f72eb8cada9e2649cd4dfdcd02ea97e83;p=xen.git unmodified drivers: use upstream sync_bitops if available The forward ported xenlinux sources in openSuSE 12.2 were switched from the old synch_bitops to the sync_bitops since kernel version 3.3. Add compat macros to use either old or new helpers depending on used kernel source version.
