[merged] latent_entropy-raise-config_frame_warn-by-default.patch removed from -mm tree

[akpm]

The patch titled
     Subject: latent_entropy: raise CONFIG_FRAME_WARN by default
has been removed from the -mm tree.  Its filename was
     latent_entropy-raise-config_frame_warn-by-default.patch

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

------------------------------------------------------
From: Kees Cook <keescook@chromium.org>
Subject: latent_entropy: raise CONFIG_FRAME_WARN by default

When building with the latent_entropy plugin, set the default
CONFIG_FRAME_WARN to 2048, since some __init functions have many basic
blocks that, when instrumented by the latent_entropy plugin, grow beyond
1024 byte stack size on 32-bit builds.
