Subject: [PATCH] x86: Changing date reference in CONFIG_SWIOTLB help from a relative to fixed point
Date: Sat, 4 Aug 2012 22:12:01 -0700 [thread overview]
Message-ID: <1344143521-30151-1-git-send-email-jmillenbach@gmail.com> (raw)
CONFIG_SWIOTLB's existing help information refers to "the current
generation of Intel's x86-64 CPUs", but the statement is no longer
true. After researching on Intel's ark site, I changed the statement
to the also true "all Intel CPUs released before 2008".
