This fixes pm_message_t vs. u32 confusion in ppc and aty (I *hope* that's basically radeon code...). I was not able to test most of these, but I'm not really changing anything, so it should be okay. Signed-off-by:

- broken sibling_map setup in x86_64 - grouping all the core and HT related cpuinfo fields. We are reasonably sure that adding new cpuinfo fields after "siblings" field, will not cause any app failure. Thats because today's /proc/cpuinfo format is completely different on x86, x86_64 and we haven't heard of any x86 app breakage because of this issue. Grouping these fields will result in more or less common format on all architectures (ia64, x86 and x86_64) and will cause less confusion. Signed-off-by:

This will allow hotplug CPU in the future and in general cleans up a lot of crufty code. It also should plug some races that the old hackish way introduces. Remove one old race workaround in NMI watchdog setup that is not needed anymore. I removed the old total sum of bogomips reporting code. The brag value of BogoMips has been greatly devalued in the last years on the open market. Real CPU hotplug will need some more work, but the infrastructure for it is there now. One drawback: the new TSC sync algorithm is less accurate than before. The old way of zeroing TSCs is too intrusive to do later. Instead the TSC of the BP is duplicated now, which is less accurate. akpm: - sync_tsc_bp_init seems to have the sense of `init' inverted. - SPIN_LOCK_UNLOCKED is deprecated - use DEFINE_SPINLOCK.

Exceptions and hardware interrupts can, to a certain degree, nest, so when attempting to follow the sequence of stacks used in order to dump their contents this has to be accounted for. Also, IST stacks have their tops stored in the TSS, so there's no need to add the stack size to get to their ends. Minor changes from AK. Signed-off-by:

Appended patch adds the support for Intel dual-core detection and displaying the core related information in /proc/cpuinfo. It adds two new fields "core id" and "cpu cores" to x86 /proc/cpuinfo and the "core id" field for x86_64("cpu cores" field is already present in x86_64). Number of processor cores in a die is detected using cpuid(4) and this is documented in IA-32 Intel Architecture Software Developer's Manual (vol 2a) (http://developer.intel.com/design/pentium4/manuals/index_new.htm#sdm_vol2a) This patch also adds cpu_core_map similar to cpu_sibling_map. Slightly hacked by AK. Signed-off-by: -

Calling a notifier three times in the debug handler does not make much sense, because a debugger can figure out the various conditions by itself. Remove the additional calls to DIE_DEBUG and DIE_DEBUGSTEP completely. This matches what i386 does now. This also makes sure interrupts are always still disabled when calling a debugger, which prevents: BUG: using smp_processor_id() in preemptible [00000001] code: tpopf/1470 caller is post_kprobe_handler+0x9/0x70 Call Trace:<ffffffff8024f10f>{smp_processor_id+191} <ffffffff80120e69>{post_kpro be_handler+9} <ffffffff80120f7a>{kprobe_exceptions_notify+58} <ffffffff80144fc0>{notifier_call_chain+32} <ffffffff80110daf>{do_debug+335} <ffffffff8010f513>{debug+127} <EOE> on preemptible debug kernels with kprobes when single stepping in user space. This was probably a bug even on non preempt kernels, this function was supposed to be running with interrupts off according to a comment there. Note to third part debugger maintainers: please double check your debugger can still single step.

They are rumoured to be much more reliable than the RIP in the stack frame on P4s. This is a borderline case because the code is very simple. Please note there are no plans to add support for all the MCE register MSRs. Cc: <venkatesh.pallipadi@intel.com> Cc: <racing.guo@intel.com> Signed-off-by:
