Those models are maintained by QEMU and may require compatibility code
to be added when making some changes. Keeping the data in the C source
code should make it simpler to handle those details.

CPUID_EXT2_SYSCALL,
Silent fix, replacing i64 with CPUID_EXT2_LM
looks like "i64" is mistake and never worked. In Intel & AMD cpuid guides
Actually it works when setting feature fields because it uses
setfeatures(), however setting i64 will set wrong bit if it's set using
add_flagname_to_bitmaps()
I'm wrong, and sorry for noise. I mixed up ia64 from feature_name with i64
from ext2_feature_name.
But question unrelated to this patch is still stand if ia64 is valid bit for
01.EDX[30]?

Order Number: 241618-030
...
Updated Table 3-5 to include the feature flag definition (EDX[30]) for
IA64 capabilities.

30 IA64 IA64 Capabilities The processor is a member of the Intel®
Itanium® processor family
and currently operating in IA32 emulation mode.

Says that it is. Along with http://en.wikipedia.org/wiki/CPUID and
http://www.sandpile.org/x86/cpuid.htm#level_0000_0001h (IA-64)
But the newest version I found (241618-037, January 2011) is back to
Reserved.
