Hi, Sheng
Since these macros are just used by kvm, and considering cross-arch
support, could you move these stuff to include/linux/kvm_host.h ? So
they can be shared for x86 and ia64.
Thanks

Yes
CONFIG_X86 is defined to compile every qemu's objects, so even if
unifdef doesn't work, we shouldn't meet the problems related to this
header file. Maybe other pential issues casues the problem you met.
Anyway we had better enable unifdef to work in its right way. :)
BTW, seems unifdef can't
The following patch should solve the issue you met before unifdef gets

Hi, Avi
This is the key fix for 2.6.28 merge. Without this patch, guest
may hang once configured with more than 2 vcpus, it is because x86 side
changed the halt handling's common logic, but it misses to change ia64
side.
