+From 3937db18a203f9936387286b95328f27013a5ffe Mon Sep 17 00:00:00 2001
+From: Peter Hutterer <peter.hutterer@who-t.net>
+Date: Mon, 29 Jun 2009 13:09:57 +1000
+Subject: [PATCH 2/4] include: introduce byte counting functions.
+
+This patch adds the following three functions:
+ bits_to_bytes(bits) - the number of bytes needed to hold 'bits'
+ bytes_to_int32(bytes) - the number of 4-byte units to hold 'bytes'
+ pad_to_int32(bytes) - the closest multiple of 4 equal to or larger than
+ 'bytes'.
+
+All three operations are common in protocol processing and currently the
+server has ((foo + 7)/8 + 3)/4 operations all over the place. A common set
+of functions reduce the error rate of these (albeit simple) calculations and
+improve readability of the code.
+
+The functions do not check for overflow.
+
+v2: backport to nx-libs 3.6.x as a prereq for
+the CVE-2015-0255 fix (Mike DePaulo)
+
+Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
