Some are new, some are due to regressions from introduction of physflat mode genapic schemes. Please consider for -mm. These are on 2.6.13-rc4-mm1 do_clustered_apic_check Needed for x86_64, removed recently from shared code. create-sysfs-onlyfor-present-cpus Create sysfs entries only for present cpus. New cpus will have them created by ACPI code when notification for the same is processed. fix-enforce-max-cpu Dont enforce this when CPU hotplug is enabled. This doesnt permit booting with maxcpus=1 and then testing logical hot-add of cpu. fix-cluster-allbutself-ipi Cluster mode also needs to prevent preempt when excluding self from online map. Propagating the fix i added for genapic_flat to cluster genapic code as well. fix-flat-mode-nobroadcast-again Recent physflat broke this for hotplug. Re-introducing it again. fix-physflat-dmode Removed un-necessary code from physflat settings. use-common-physflat-cluster Used common code for genapic-physflat and cluster since they share a lot of code was duplicated instead of sharing them. choose-physflat-onlyfor-gt8cpus-amd Choose physflat only when >8 cpus. We could still use flat mode without broadcast shortcut. The mask version of IPI is still effective and more performant than the unicast version thats required when we use physical mode. Cheers, ashok
