The patch titled
     Subject: arc: use for_each_sg()
has been removed from the -mm tree.  Its filename was
     arc-use-for_each_sg.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Akinobu Mita <akinobu.mita@xxxxxxxxx>
Subject: arc: use for_each_sg()

This replaces the plain loop over the sglist array with for_each_sg()
macro which consists of sg_next() function calls.  Since arc doesn't
select ARCH_HAS_SG_CHAIN, it is not necessary to use for_each_sg() in
order to loop over each sg element.  But this can help find problems with
drivers that do not properly initialize their sg tables when
CONFIG_DEBUG_SG is enabled.
