Subject: [PATCH] efifb: Don't show the mapping VA
Date: Wed, 11 May 2016 16:57:47 -0700 [thread overview]
Message-ID: <c980a1a405f54b39fc6382c20182786c894c7ffd.1463011030.git.luto@kernel.org> (raw)
The framebuffer mapping virtual address leaks information about the
kernel memory layout. Stop logging it.
