latent_entropy: raise CONFIG_FRAME_WARN by default
PATCH 1/1 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.
