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.
The new menu is also moved to the end of the x86 options.
