* [PATCH] md: make md threads interruptible againNeilBrown2005-11-15
| | | | | | | | | | | | | Despite the fact that md threads don't need to be signalled, and won't respond to signals anyway, we need to have an 'interruptible' wait, else they stay in 'D' state and add to the load average. (akpm: the signal_pending() test is unneeded - we'll fix that up in the next round. For now, leave it there because that's how the code used to be).

* [PATCH] knfsd: make sure nfsd doesn't hog a cpu foreverNeilBrown2005-11-15
| | | | | | | | | | | | | | | Being kernel-threads, nfsd servers don't get pre-empted (depending on CONFIG). If there is a steady stream of NFS requests that can be served from cache, an nfsd thread may hold on to a cpu indefinitely, which isn't very friendly. So it is good to have a cond_resched in there (just before looking for a new request to serve), to make sure we play nice.

| * [PATCH] x86_64: Remove CONFIG_CHECKING and add command line option for ↵Andi Kleen2005-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pagefault tracing CONFIG_CHECKING covered some debugging code used in the early times of the port. But it wasn't even SMP safe for quite some time and the bugs it checked for seem to be gone. This patch removes all the code to verify GS at kernel entry. There haven't been any new bugs in this area for a long time. Previously it also covered the sysctl for the page fault tracing. That didn't make much sense because that code was unconditionally compiled in. I made that a boot option now because it is typically only useful at boot.

| * [PATCH] x86_64: Make node boundaries consistentMagnus Damm2005-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current x86_64 NUMA memory code is inconsequent when it comes to node memory ranges. The exact behaviour varies depending on which config option that is used. setup_node_bootmem() has start and end as arguments and these are used to calculate the size of the node like this: (end - start). This is all fine if end is pointing to the first non-available byte. The problem is that the current x86_64 code sometimes treats it as the last present byte and sometimes as the first non-available byte. The result is that some configurations might lose a page at the end of the range. This patch tries to fix CONFIG_ACPI_NUMA, CONFIG_K8_NUMA and CONFIG_NUMA_EMU so they all treat the end variable as the first non-available byte. This is the same way as the single node code. The patch is boot tested on dual x86_64 hardware with the above configurations, but maybe the removed code is needed as some workaround?

| * [PATCH] x86_64: Make ACPI NUMA and NUMA emulation peers of K8_NUMA in KconfigRavikiran G Thirumalai2005-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On x86_64 arches, there is no way to choose ACPI_NUMA without having to choose K8_NUMA. CONFIG_K8_NUMA is not needed for Intel EM64T NUMA boxes. It also looks odd if you have to select ACPI_NUMA from the power management menu. This patch fixes those oddities. Patch does the following: 1. Makes NUMA a config option like other arches 2. Makes topology detection options like K8_NUMA dependent on NUMA 3. Choosing ACPI NUMA detection can be done from the standard "Processor type and features" menu AK: I fixed up the dependencies and changed the help texts a bit on top of Kiran's patch.

| * [PATCH] x86_64: Use common sys_time64Paolo 'Blaisorblade' Giarrusso2005-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keeping this function does not makes sense because it's a copied (and buggy) copy of sys_time. The only difference is that now.tv_sec (which is a time_t, i.e. a 64-bit long) is copied (and truncated) into a int (32-bit). The prototype is the same (they both take a long __user *), so let's drop this and redirect it to sys_time (and make sure it exists by defining __ARCH_WANT_SYS_TIME). Only disadvantage is that the sys_stime definition is also compiled (may be fixed if needed by adding a separate __ARCH_WANT_SYS_STIME macro, and defining it for all arch's defining __ARCH_WANT_SYS_TIME except x86_64).

| * [PATCH] x86_64: Set ____cacheline_maxaligned_in_smp alignment to 128 bytesPaolo 'Blaisorblade' Giarrusso2005-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current value was correct before the introduction of Intel EM64T support - but now L1_CACHE_SHIFT_MAX can be less than L1_CACHE_SHIFT, which _is_ funny! Between the few users of ____cacheline_maxaligned_in_smp, we also have (for example) rcu_ctrlblk, and struct zone, with zone->{lru_,}lock. I.e. we have a lot of excess cacheline bouncing on them. No correctness issues, obviously. So this could even be merged for 2.6.14 (I'm not a fan of this idea, though).

| * [PATCH] x86_64: New heuristics to find out hotpluggable CPUs.Andi Kleen2005-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With a NR_CPUS==128 kernel with CPU hotplug enabled we would waste 4MB on per CPU data of all possible CPUs. The reason was that HOTPLUG always set up possible map to NR_CPUS cpus and then we need to allocate that much (each per CPU data is roughly ~32k now) The underlying problem is that ACPI didn't tell us how many hotplug CPUs the platform supports. So the old code just assumed all, which would lead to this memory wastage. This implements some new heuristics: - If the BIOS specified disabled CPUs in the ACPI/mptables assume they can be enabled later (this is bending the ACPI specification a bit, but seems like a obvious extension) - The user can overwrite it with a new additionals_cpus=NUM option - Otherwise use half of the available CPUs or 2, whatever is more.
