So Avi suggested that we can add more fields to flags rather than a > new catagory. FWIW when I added the "power management:" flags back then for the 64bit kernel I didn't get any reports of user programs breaking. Also some other fields got added like cpu cores or initial apicid etc. and that also didn't lead to breakage. So adding new lines to cpuinfo should be ok. -Andi -- ak@linux.intel.com
