This changeset reverts two previous corrections, for reasons that escape me. First, the domain map is again being confined to NR_CPUS, which I had submitted a patch to fix recently (yes, I realize the code has a TODO in there, but those really get forgotten about far too often). Second, the platform hypercall was reverted back to require all information to be passed to Xen in one chunk, whereas

This fixes an actual bug (failure to exit from a function after an allocation failure), an inconsistency (not removing the cpufreq_dom list member upon failure), and a latent bug (not clearing the current governor upon governor initialization failure when there was no old one; latent because the only current code path leading to this situation frees the policy upon failure and hence the governor not getting cleared is benign)....

struct cpufreq_policy, including a cpumask_t member, gets copied in cpufreq_limit_change(), cpufreq_add_cpu(), set_cpufreq_gov(), and set_cpufreq_para(). Make the member a cpumask_var_t, thus reducing the amount of data needing copying (particularly with large NR_CPUS). Signed-off-by: Jan Beulich <jbeulich@sus...

David, So here are the two patches. Remove all patches that you have and apply these. The first one is straight forward. The second one will hopefully fix the livelock issue you have been encountering. People reviewing the patches should note that the second one is slightly different than the one I posted earlier. It removes the BUG_ON in the if condition where we jump to update_holders. The
