The patch titled
x86: use elfnote.h to generate vsyscall notes.
has been removed from the -mm tree. Its filename was
x86-use-elfnoteh-to-generate-vsyscall-notes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: x86: use elfnote.h to generate vsyscall notes.
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
Use existing elfnote.h to generate vsyscall notes, rather than doing it
locally. Changes elfnote.h a bit to suite, since this is the first asm user,
and it wasn't quite right.
