2009-12-15x86, msr/cpuid: Register enough minors for the MSR and CPUID driversH. Peter Anvin
register_chrdev() hardcodes registering 256 minors, presumably to avoid breaking old drivers. However, we need to register enough minors so that we have all possible CPUs. checkpatch warns on this patch, but the patch is correct: NR_CPUS here is a static *upper bound* on the *maximum CPU index* (not *number of CPUs!*) and that is what we want.

2009-12-15x86: Split swiotlb initialization into two stagesFUJITA Tomonori
The commit f4780ca005404166cc40af77ef0e86132ab98a81 moves swiotlb initialization before dma32_free_bootmem(). It's supposed to fix a bug that the commit 75f1cdf1dda92cae037ec848ae63690d91913eac introduced, we initialize SWIOTLB right after dma32_free_bootmem so we wrongly steal memory area allocated for GART with broken BIOS earlier. However, the above commit introduced another problem, which likely breaks machines with huge amount of memory. Such a box use the majority of DMA32_ZONE so there is no memory for swiotlb. With this patch, the x86 IOMMU initialization sequence are: 1. We set swiotlb to 1 in the case of (max_pfn > MAX_DMA32_PFN && !no_iommu). If swiotlb usage is forced by the boot option, we go to the step 3 and finish (we don't try to detect IOMMUs). 2. We call the detection functions of all the IOMMUs. The detection function sets x86_init.iommu.iommu_init to the IOMMU initialization function (so we can avoid calling the initialization functions of all the IOMMUs needlessly). 3. We initialize swiotlb (and set dma_ops to swiotlb_dma_ops) if swiotlb is set to 1. 4. If the IOMMU initialization function doesn't need swiotlb (e.g. the initialization is sucessful) then sets swiotlb to zero. 5. If we find that swiotlb is set to zero, we free swiotlb resource.

2009-12-14x86: Regex support and known-movable symbols for relocs, fix _endH. Peter Anvin
This adds a new category of symbols to the relocs program: symbols which are known to be relative, even though the linker emits them as absolute; this is the case for symbols that live in the linker script, which currently applies to _end. Unfortunately the previous workaround of putting _end in its own empty section was defeated by newer binutils, which remove empty sections completely. This patch also changes the symbol matching to use regular expressions instead of hardcoded C for specific patterns. This is a decidedly non-minimal patch: a modified version of the relocs program is used as part of the Syslinux build, and this is basically a backport to Linux of some of those changes; they have thus been well tested.

2009-12-14x86, msr: Remove incorrect, duplicated code in the MSR driverH. Peter Anvin
The MSR driver would compute the values for cpu and c at declaration, and then again in the body of the function. This isn't merely redundant, but unsafe, since cpu might not refer to a valid CPU at that point. Remove the unnecessary and dangerous references in the declarations. This code now matches the equivalent code in the CPUID driver. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

2009-12-14x86, mce: Thermal monitoring depends on APIC being enabledCyrill Gorcunov
Add check if APIC is not disabled since thermal monitoring depends on it. As only apic gets disabled we should not try to install "thermal monitor" vector, print out that thermal monitoring is enabled and etc... Note that "Intel Correct Machine Check Interrupts" already has such a check. Also I decided to not add cpu_has_apic check into mcheck_intel_therm_init since even if it'll call apic_read on disabled apic -- it's safe here and allow us to save a few code bytes.

2009-12-14x86: Gart: fix breakage due to IOMMU initialization cleanupYinghai Lu
This fixes the following breakage of the commit 75f1cdf1dda92cae037ec848ae63690d91913eac: - GART systems that don't AGP with broken BIOS and more than 4GB memory are forced to use swiotlb. They can allocate aperture by hand and use GART. - GART systems without GAP must disable GART on shutdown. - swiotlb usage is forced by the boot option, gart_iommu_hole_init() is not called, so we disable GART early_gart_iommu_check().

2009-12-11x86: Limit the number of processor bootup messagesMike Travis
When there are a large number of processors in a system, there is an excessive amount of messages sent to the system console. It's estimated that with 4096 processors in a system, and the console baudrate set to 56K, the startup messages will take about 84 minutes to clear the serial port. This set of patches limits the number of repetitious messages which contain no additional information. Much of this information is obtainable from the /proc and /sysfs. Some of the messages are also sent to the kernel log buffer as KERN_DEBUG messages so dmesg can be used to examine more closely any details specific to a problem. The new cpu bootup sequence for system_state == SYSTEM_BOOTING: Booting Node 0, Processors #1 #2 #3 #4 #5 #6 #7 Ok. Booting Node 1, Processors #8 #9 #10 #11 #12 #13 #14 #15 Ok. ... Booting Node 3, Processors #56 #57 #58 #59 #60 #61 #62 #63 Ok. Brought up 64 CPUs After the system is running, a single line boot message is displayed when CPU's are hotplugged on: Booting Node %d Processor %d APIC 0x%x Status of the following lines: CPU: Physical Processor ID: printed once (for boot cpu) CPU: Processor Core ID: printed once (for boot cpu) CPU: Hyper-Threading is disabled printed once (for boot cpu) CPU: Thermal monitoring enabled printed once (for boot cpu) CPU %d/0x%x -> Node %d: removed CPU %d is now offline: only if system_state == RUNNING Initializing CPU#%d: KERN_DEBUG Signed-off-by: Mike Travis <travis@sgi.com> LKML-Reference: <4B219E28.8080601@sgi.com> Signed-off-by: H.

It turns out the BIOS is using the first 64k for mptable, without reserving it.

2009-12-11x86, AMD: Fix stale cpuid4_info shared_map data in shared_cpu_map cpumasksPrarit Bhargava
The per_cpu cpuid4_info shared_map can contain stale data when CPUs are added and removed. The stale data can lead to a NULL pointer derefernce panic on a remove of a CPU that has had siblings previously removed. This patch resolves the panic by verifying a cpu is actually online before adding it to the shared_cpu_map, only examining cpus that are part of the same lower level cache, and by updating other siblings lowest level cache maps when a cpu is added.
