target/i386: check CPUID_PAE to determine 36 bit processor address space
PAE mode in x86 supports 36 bit address space. Check the PAE CPUID on the guest processor and set phys_bits to 36 if PAE feature is set. This is in addition to checking the presence of PSE36 CPUID feature for setting 36 bit phys_bits. Signed-off-by: Ani Sinha <anisinha@redhat.com> Acked-by: Michael S.
