The patch titled
     Subject: test_hexdump: test all possible group sizes for overflow
has been removed from the -mm tree.  Its filename was
     test_hexdump-test-all-possible-group-sizes-for-overflow.patch

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

------------------------------------------------------
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Subject: test_hexdump: test all possible group sizes for overflow

Currently the only one combination is tested for overflow, i.e.  rowsize =
16, groupsize = 1, len = 1.  Do various test to go through all possible
branches.
