[akpm]

The patch titled
     iommu sg: kill __clear_bit_string and find_next_zero_string
has been removed from the -mm tree.  Its filename was
     iommu-sg-kill-__clear_bit_string-and-find_next_zero_string.patch

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

------------------------------------------------------
Subject: iommu sg: kill __clear_bit_string and find_next_zero_string
From: FUJITA Tomonori <tomof@acm.org>

This kills unused __clear_bit_string and find_next_zero_string (they
were used by only gart and calgary IOMMUs).
