Subject: [PATCH 01/12] x86 Kconfig: create extended platforms menu
From: Dave Hansen <dave.hansen@...ux.intel.com>
This takes the relatively obscure (NUMA-Q anyone?) platforms
(both 32 and 64-bit) and sticks them in their own menu.
Virtually nobody needs to set these, and those that do know how
to find them the hard way.
