From 2d9ce177e68645945e3366cfe2d66ee3c28cd4f2 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Thu, 19 Jul 2007 14:30:14 +0300 Subject: i386: Allow KVM on i386 nonpae Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of the cmpxchg64b feature and enables compilation of the set_64bit() family. Since the option is dependent on PAE, and since KVM depends on set_64bit(), this effectively disables KVM on i386 nopae. Simplify by removing the config option altogether: the boot check is made dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed without constraints. It is up to users to check for the feature flag (KVM does not as virtualiation extensions imply its existence).
