More Coverity-reported issues.
Another bundle of issues from Coverity triage. The first one is in x86/mm, and looks scarier than it is. The others are all in xen/drivers and AFAICT are pretty minor. Cheers, Tim.

Questions on cpu frequency scaling AMD vs. Intel
...ltage X2, also runs at 2500 max.) My question: why don't the Intel CPUs don't scale up on demand? Could there be a bug in the driver that it measures overall utilization (which is at 50% most of the time) and not single core utilization, thus never reaching the threshold for scaling up? up_threshold is at 80 for both CPUs. (cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold) I have a somewhat related question. That very new AMD CPU mentioned above was not recognized by CentOS 5.2 and the current frequency was shown as 800000 (instead of 2500000), although it was running in full...
