[Andrew Morton]

The quilt patch titled
     Subject: minmax: allow comparisons of 'int' against 'unsigned char/short'
has been removed from the -mm tree.  Its filename was
     minmax-allow-comparisons-of-int-against-unsigned-char-short.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: minmax: allow comparisons of 'int' against 'unsigned char/short'

Since 'unsigned char/short' get promoted to 'signed int' it is safe to
compare them against an 'int' value.
