 use

Hi Jeremy,

First of all, thanks for tackling this issue.

I tried applying this patchset to tip:x86/paravirt, but I got the
following build error when applied on top of tip:x86/core:

/home/hpa/kernel/linux-2.6-tip.paravirt/arch/x86/include/asm/paravirt.h:
In function ‘pud_val’:
/home/hpa/kernel/linux-2.6-tip.paravirt/arch/x86/include/asm/paravirt.h:1324:
error: invalid operands to binary == (have ‘struct paravirt_callee_save’
and ‘void *’)


The failing configuration was x86-64 "make allyesconfig".
