This patch adds a boot parameter to allow a kernel to be booted
with the option to skip the SRAT check.  There are BIOSes in
                                         ^^^^^^^^^^^^^^^^^^^
production that have these failures, so this will allow people
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
in the field to work around these BIOS issues.

that it is not necessary to have DMI quirks for preproduction BIOSes.
