+Subject: [PATCH] x86: Modify ENTRY in sysdep.h so that p2align can be
+ specified
+Content-type: text/plain; charset=UTF-8
+
+No bug.
+
+This change adds a new macro ENTRY_P2ALIGN which takes a second
+argument, log2 of the desired function alignment.
+
+The old ENTRY(name) macro is just ENTRY_P2ALIGN(name, 4) so this
+doesn't affect any existing functionality.
