The following patch fixes a bug in the emulation of the xchg instruction. This bug has prevented us from booting fully virtualized SMP guests that write to the APIC using the xchg instruction (when CONFIG_X86_GOOD_APIC is not set). On 32 bit platforms, sles 10 kernels are built without CONFIG_x86_GOOD_APIC not set and hence we have had problems booting fully virtualized SMP sles 10 guests. Signed- off- by K. Y. Srinivasan <ksrinivasan@xxxxxxxxxx>
