[2.6 patch] x86: allow 64bit setting in Kconfig

From: Adrian Bunk
Date: Mon Jan 28 2008 - 17:09:47 EST


Recently someone told me he had a bug on x86 and to reproduce
it I should "'make allyesconfig' and disable CONFIG_HOTPLUG=y".

But I didn't see it.

"make allyesconfig" is ambiguous on x86 and he had a 64bit computer.

There go another two hours compile time.

It makes sense to have the Kconfig default and the defconfig based on
whether you are on a 32bit or a 64bit machine, but it's complete
nonsense to not offer the Kconfig variable unless you had explicitely
given ARCH=x86 (in which case you could as well immediately set the ARCH
to i386 or x86_64).

Say yes to build a 64-bit kernel - formerly known as x86_64
