The patch titled amiserial: prepare for locking relaxation in caller has been removed from the -mm tree. Its filename was amiserial-prepare-for-locking-relaxation-in-caller.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: amiserial: prepare for locking relaxation in caller From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx> Just wrap this one in a lock_kernel. As I understand it there is no M68K SMP anyway.
