- add-sys-kernel-notes.patch removed from -mm tree

[akpm@xxxxxxxxxxxxxxxxxxxx]

The patch titled
     Add /sys/kernel/notes
has been removed from the -mm tree.  Its filename was
     add-sys-kernel-notes.patch

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

------------------------------------------------------
Subject: Add /sys/kernel/notes
From: Roland McGrath <roland@xxxxxxxxxx>

This patch adds the /sys/kernel/notes magic file.  Reading this delivers the
contents of the kernel's .notes section.  This lets userland easily glean any
detailed information about the running kernel's build that was stored there at
compile time.
