The patch titled
uml: mark some tt-mode code
has been removed from the -mm tree. Its filename is
uml-mark-some-tt-mode-code.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: uml: mark some tt-mode code
From: Jeff Dike <jdike@xxxxxxxxxxx>
Mark a symbol and file as being tt-mode only. This shrinks the binary
slightly when tt mode support is compiled out and makes it easier to identity
stuff when tt mode is removed.
