[merged] binfmt_misc-simplify-entry_status.patch removed from -mm tree

[akpm@xxxxxxxxxxxxxxxxxxxx]

The patch titled
     Subject: fs/binfmt_misc.c: simplify entry_status()
has been removed from the -mm tree.  Its filename was
     binfmt_misc-simplify-entry_status.patch

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

------------------------------------------------------
From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: fs/binfmt_misc.c: simplify entry_status()

sprintf() reliably returns the number of characters printed, so we don't
need to ask strlen() where we are.  Also replace calling sprintf("%02x")
in a loop with the much simpler bin2hex().

[akpm@xxxxxxxxxxxxxxxxxxxx: it's odd to include kernel.h after everything else]
