2006-02-27Make Kprobes depend on modulesLinus Torvalds
Commit 9ec4b1f356b3bad928ae8e2aa9caebfa737d52df made kprobes not compile without module support, so just make that clear in the Kconfig file. Also, since it's marked EXPERIMENTAL, make that dependency explicit too. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-02-27[SPARC64]: Make cpu_present_map available earlier.David S. Miller
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>
2006-02-27[PATCH] fix voyager after topology.c moveJames Bottomley
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).

2006-02-26[PATCH] x86_64: Better ATI timer fixAndi Kleen
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.

2006-02-26[PATCH] x86_64: Move the SMP time selection earlierAndi Kleen
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>

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.

2006-02-26[PATCH] x86_64: no_iommu removal in pci-gart.cJon Mason
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.

2006-02-24[PATCH] Fix topology.c locationZachary Amsden
When compiling a non-default subarch, topology.c is missing from the kernel build. This causes builds with CONFIG_HOTPLUG_CPU to fail. In addition, on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to reference uninitialized data that should have been set up by the initcall in topology.c which calls register_cpu. This causes a kernel panic on boot on newer Intel processors. Moving topology.c to arch/i386/kernel fixes both of these problems. Thanks to Dan Hecht for finding and fixing this problem.

2006-02-24[PATCH] flags parameter for linkatUlrich Drepper
I'm currently at the POSIX meeting and one thing covered was the incompatibility of Linux's link() with the POSIX definition. The name. Linux does not follow symlinks, POSIX requires it does. Even if somebody thinks this is a good default behavior we cannot change this because it would break the ABI. But the fact remains that some application might want this behavior. We have one chance to help implementing this without breaking the behavior. For this we could use the new linkat interface which would need a new flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new behavior could be invoked. I do not want to introduce such a patch now. But we could add the parameter now, just don't use it. The patch below would do this. Can we get this late patch applied before the release more or less fixes the syscall API?

2006-02-24[PATCH] x86: fix broken SMP boot sequenceJames Bottomley
Recent GDT changes broke the SMP boot sequence if the booting CPU is numbered anything other than zero. There's also a subtle source of error in that the boot time CPU now uses cpu_gdt_table (which is actually the GDT for booting CPUs in head.S). This patch fixes both problems by making GDT descriptors themselves allocated from a per_cpu area and switching to them in cpu_init(), which now means that cpu_gdt_table is exclusively used for booting CPUs again.
