Subject: [PATCH] x86: Changing date reference in CONFIG_SWIOTLB help from a relative to fixed point

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".
