IPF SDM 2.2 changes definition of PAL_LOGICAL_TO_PHYSICAL to add proc_number=-1 to get core/thread mapping info on the running processer. Based on this change, we had better to update existing core/thread detection in IA64 kernel correspondingly. The attached patch implements this change. It simplifies detection code and eliminates potential race condition. It also runs a bit faster and has better scalability especially when cores and threads number grows up in one package.

Because PAL spec has changed since 2002, you can goto http://developer.intel.com/design/itanium/manuals/iiasdmanual.htm to download new SDM, all PAL calls should be invoked with psr.ic=1, and it's caller's responsibility to handle possible tlb miss. Ia64_pal_cache_flush was written according to old spec, it is obsolete, and this patch has ia64_pal_cache_flush conform to new spec.

Patch to support P-state transitions on ia64. This driver is based on ACPI, and uses the ACPI processor driver interface to find out the P-state support information for the processor. This driver plugs into generic cpufreq infrastructure. Once this driver is loaded successfully, ondemand/userspace governor can be used to change the CPU frequency dynamically based on load or on request from userspace process.

Version 3 - rediffed to apply on top of Ashok's hotplug cpu patch. /proc/cpuinfo output in step with x86. This is an updated MC/MT identification patch based on the previous discussions on list. Add the Multi-core and Multi-threading detection for IPF. - Add new core and threading related fields in /proc/cpuinfo. Physical id Core id Thread id Siblings - setup the cpu_core_map and cpu_sibling_map appropriately - Handles Hot plug CPU Signed-off-by: NSuresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: NGordon Jin <gordon.jin@intel.com> Signed-off-by: NRohit Seth <rohit.seth@intel.com> Signed-off-by: NTony Luck <tony.luck@intel.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
