New version that switches to the common onstack completion and just a pointer in the platform_data struct idiom. This gets rid of all the flags fiddling.

| * [SPARC64]: Make cpu_present_map available earlier.David S. Miller2006-02-26
| | | | | | | | | | | | | | | | | | | | | | | | The change to kernel/sched.c's init code to use for_each_cpu() requires that the cpu_possible_map be setup much earlier. Set it up via setup_arch(), constrained to NR_CPUS, and later constrain it to max_cpus in smp_prepare_cpus(). This fixes SMP booting on sparc64. Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] fix voyager after topology.c moveJames Bottomley2006-02-26
| | | | | | | | | | | | | | | | Commit 9c869edac591977314323a4eaad5f7633fca684f broke voyager again rather subtly because it already had its own topology exporting functions, so now each CPU gets registered twice. I think we can actually use the generic ones, so I don't propose reverting it. The attached should eliminate the voyager topology functions in favour of the generic ones. I also added a define to ensure voyager is never hotplug CPU (we don't have the support in the SMP harness).

* [PATCH] x86_64: Better ATI timer fixAndi Kleen2006-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous experiment for using apicmaintimer on ATI systems didn't work out very well. In particular laptops with C2/C3 support often don't let it tick during idle, which makes it useless. There were also some other bugs that made the apicmaintimer often not used at all. I tried some other experiments - running timer over RTC and some other things but they didn't really work well neither. I rechecked the specs now and it turns out this simple change is actually enough to avoid the double ticks on the ATI systems. We just turn off IRQ 0 in the 8254 and only route it directly using the IO-APIC. I tested it on a few ATI systems and it worked there. In fact it worked on all chipsets (NVidia, Intel, AMD, ATI) I tried it on. According to the ACPI spec routing should always work through the IO-APIC so I think it's the correct thing to do anyways (and most of the old gunk in check_timer should be thrown away for x86-64). But for 2.6.16 it's best to do a fairly minimal change: - Use the known to be working everywhere-but-ATI IRQ0 both over 8254 and IO-APIC setup everywhere - Except on ATI disable IRQ0 in the 8254 - Remove the code to select apicmaintimer on ATI chipsets - Add some boot options to allow to override this (just paranoia) In 2.6.17 I hope to switch the default over to this for everybody.

* [PATCH] x86_64: Move the SMP time selection earlierAndi Kleen2006-02-26
| | | | | | | | | | | | | | | | | | SMP time selection originally ran after all CPUs were brought up because it needed to know the number of CPUs to decide if it needs an MP safe timer or not. This is not needed anymore because we know present CPUs early. This fixes a couple of problems: - apicmaintimer didn't always work because it relied on state that was set up time_init_gtod too late. - The output for the used timer in early kernel log was misleading because time_init_gtod could actually change it later. Now always print the final timer choice Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] x86_64: Disable ACPI blacklist by year for now on x86-64Andi Kleen2006-02-26
| | | | | | | | | | | | | | | | | ACPI is initialized very early on x86-64, before the DMI code is initialized. This means it would often discover a 0 year and then turn off ACPI because it thought the BIOS was too old. Some systems don't boot without ACPI so this was a problem. I have a full fix by adding new very early DMI detection, but it needs more testing before it can be merged. For 2.6.16 let's just turn the check off. It never made much sense anyways because there are no x86-64 systems older than 2002 or so and they generally all have working ACPI.

* [PATCH] x86-64/i386: Use common X86_PM_TIMER option and make it EMBEDDEDAndi Kleen2006-02-26
| | | | | | | | | | | | | | | | This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi And since PM timer is needed for correct timing on a lot of systems now (e.g. AMD dual cores) and we often get bug reports from people who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had this change before and it's a good thing.

* [PATCH] x86_64: no_iommu removal in pci-gart.cJon Mason2006-02-26
| | | | | | | | | | | | | | | | | | | In previous versions of pci-gart.c, no_iommu was used to determine if IOMMU was disabled in the GART DMA mapping functions. This changed in 2.6.16 and now gart_xxx() functions are only called if gart is enabled. Therefore, uses of no_iommu in the GART code are no longer necessary and can be removed. Also, it removes double deceleration of no_iommu and force_iommu in pci.h and proto.h, by removing the deceleration in pci.h. Lastly, end_pfn off by one error. Tested (along with patch 1/2) on dual opteron with gart enabled, iommu=soft, and iommu=off.
