Performance tests showed that ULOG may fail on heavy loaded systems because of failed order-N allocations (N >= 1). The default value of 4096 is not optimal in the sense that it actually allocates _two_ contigous physical pages. Reasoning: ULOG uses alloc_skb(), which adds another ~300 bytes for skb_shared_info. This patch sets the default value to NLMSG_GOODSIZE and adds some documentation at the top. Signed-off-by:

When two ip_route_output_key lookups in icmp_send were combined I forgot to change the error path for ip_options_echo to not drop the dst reference since it now sits before the dst lookup. To fix it we simply jump past the ip_rt_put call. Signed-off-by:

This patch contains a printk reorder to remove the current problem of displaying "PCI-DMA: Disabling IOMMU." and then "PCI-DMA: using GART IOMMU" 20 lines later in dmesg. It also constains a printk reorder in swiotlb to state swiotlb enablement prior to describing the location of the bounce buffers, and a printk reorder to state gart enablement prior to describing the aperature. Also constains a whitespace cleanup in arch/x86_64/kernel/setup.c Tested (along with patch 2/2) on dual opteron with gart enabled, iommu=soft, and iommu=off. Signed-off-by:

Hack for 2.6.16. In 2.6.17 all code that uses NR_CPUs should be audited and changed to only touch possible CPUs. Don't mark the reference per cpu data init data (so it stays around after boot) and point all impossible CPUs to it. This way they reference some valid - although shared memory. Usually this is only initialization like INIT_LIST_HEADs and there won't be races because these CPUs never run. Still somewhat hackish. Signed-off-by:

Some broken BIOS's had processors disabled, but same apic id as a valid processor. This causes acpi_processor_start() to think this disabled cpu is ok, and croak. So we dont record bad apicid's anymore. http://bugzilla.kernel.org/show_bug.cgi?id=5930Signed-off-by:

On some broken motherboards (at least one NForce3 based AMD64 laptop) the PIT timer runs at a incorrect frequency. This patch adds a new option "apicpmtimer" that allows to use the APIC timer and calibrate it using the PMTimer. It requires the earlier patch that allows to run the main timer from the APIC. Specifying apicpmtimer implies apicmaintimer. The option defaults to off for now. I tested it on a few systems and the resulting APIC timer frequencies were usually a bit off, but always <1%, which should be tolerable. TBD figure out heuristic to enable this automatically on the affected systems TBD perhaps do it on all NForce3s or using DMI? Signed-off-by:

kprobes cannot deal with the funny calling conventions when it runs on a different stack when it returns. If someone wants to instrument context switch they can add a probe to schedule() instead. Cc: jkenisto@us.ibm.com, prasanna@in.ibm.com Signed-off-by:

Align the start of the per-cpu section to the configured number of bytes in a cache line. This stops a BUG_ON() from triggering in load_module() when DEFINE_PER_CPU() is used in a module and the section isn't cacheline-aligned. Rusty also found this and sent a patch in a while ago (http://lkml.org/lkml/2004/10/19/17), I don't know what came of that. Signed-off-by:

[ AK: I redid Kevin's fix to be simpler, but the idea and original analysis of the problem is from Kevin] This avoid allocation failures on some SATA systems like Nvidia CK8 when the IOMMU gets fragmented. Modern SATA devices have quite large queues (128 entries) and the FS with ext2/3 is good enough now that it often passes whole 128 page sg lists down to the driver. These require 512K of continuous free space in the IOMMU aperture to map when merged. When the IOMMU is fragmented this could lead to spurious IO errors due to failing mappings. Short term fix is to just try to map the SG list again unmerged page by page - this way fragmentation doesn't matter anymore. The code for that was already there, but it just wasn't enabled for the merge case. According to Kevin at least the Nvidia device doesn't seem to benefit from merging much anyways, so the only slowdown is from trying to do an unnecessary merge attempt. Kevin plans to implement better fragmentation avoidance in the future, but that wouldn't be 2.6.16 material. TBD: should add some statistic counters to count how often that really happens.

attached patch is 2 more cases i found via running the reference_init.pl script. These were easy to spot just knowing the file names. There is one another about init/main.c that i cant exactly zero in. (partly because i dont know how to interpret the data thats spewed out of the tool). Signed-off-by:

Currently, x86_64 and ia64 arches do not clear the corresponding bits in the node's cpumask when a cpu goes down or cpu bring up is cancelled. This is buggy since there are pieces of common code where the cpumask is checked in the cpu down code path to decide on things (like in the slab down path). PPC does the right thing, but x86_64 and ia64 don't (This was the reason Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce on other arches). This patch fixes it for x86_64. I won't attempt ia64 as I cannot test it. Credit for spotting this should go to Alok. Signed-off-by:

They cause quite bad performance regressions on Netburst This is temporary until we can get new optimized functions for these CPUs. This undoes changes that were done in 2.6.15 and in 2.6.16-rc1, essentially bringing the code back to 2.6.14 level. Only change is I renamed the X86_FEATURE_K8_C flag to X86_FEATURE_REP_GOOD and fixed the check for the flag and also fixed some comments. Signed-off-by:

They all have problems with IRQ 0 routing, so just use the APIC on them. Can be overwritten with "noapicmaintimer" Signed-off-by:

Andi Kleen authored
Another piece from the no-idle-tick patch. This can be enabled with the "apicmaintimer" option. This is mainly useful when the PIT/HPET interrupt is unreliable. Note there are some systems that are known to stop the APIC timer in C3. For those it will never work, but this case should be automatically detected. It also only works with PM timer right now. When HPET is used the way the main timer handler computes the delay doesn't work. It should be a bit more efficient because there is one less regular interrupt to process on the boot processor.
