* [PATCH] x86_64: Fix numa node topology detection for srat based x86_64 boxesRavikiran G Thirumalai2005-10-03
| | | | | | | | | | | | | | | 2.6.14-rc2 does not assign cpus to proper nodeids on our em64t numa boxen. Our boxes use acpi srat for parsing the numa information. srat_detect_node() used phys_proc_id[] to get to the cpu's local apic id, but phys_proc_id[] represents the cpu<->initial_apic_id mapping. The following patch fixes this problem. Now apicid_to_node[] is properly indexed with the local apic id.

The model name (PowerBook6,7) is taken from a 12" iBook, I don't know if it also matches the 14" version. The patch applies to a vanilla 2.6.13.2 kernel.

* [PATCH] pmac: fix cpufreq for old tipb 550MhzBenjamin Herrenschmidt2005-09-30
| | | | | | | | | | | | | | The old 550Mhz titanium powerbook can switch to a lower frequency (500Mhz). A user has been repeately reporting overtemp conditions on his machine at high speed so this simple patch adds support to PowerMac cpufreq for this machine. The difference in frequency isn't big but seem enough to fix that user's problems. The patch has been around for some time now and doesn't seem to cause any problem, so I suppose it could go in now.

* [PATCH] x86_64 early numa init fixRavikiran G Thirumalai2005-09-30
| | | | | | | | | | | | | | | | | | | | | The tests Alok carried out on Petr's box confirmed that cpu_to_node[BP] is not setup early enough by numa_init_array due to the x86_64 changes in 2.6.14-rc*, and unfortunately set wrongly by the work around code in numa_init_array(). cpu_to_node[0] gets set with 1 early and later gets set properly to 0 during identify_cpu() when all cpus are brought up, but confusing the numa slab in the process. Here is a quick fix for this. The right fix obviously is to have cpu_to_node[bsp] setup early for numa_init_array(). The following patch will fix the problem now, and the code can stay on even when cpu_to_node{BP] gets fixed early correctly. Thanks to Petr for access to his box.

* [PATCH] x86_64: fix the BP node_to_cpumaskRavikiran G Thirumalai2005-09-30
| | | | | | | | | | | | | | | Fix the BP node_to_cpumask. 2.6.14-rc* broke the boot cpu bit as the cpu_to_node(0) is now not setup early enough for numa_init_array. cpu_to_node[] is setup much later at srat_detect_node on acpi srat based em64t machines. This seems like a problem on amd machines too, Tested on em64t though. /sys/devices/system/node/node0/cpumap shows up sanely after this patch.

* [PATCH] utilization of kprobe_mutex is incorrect on x86_64Zhang, Yanmin2005-09-30
| | | | | | | | | | | | | | | The up()/down() orders are incorrect in arch/x86_64/kprobes.c file. kprobe_mutext is used to protect the free kprobe instruction slot list. arch_prepare_kprobe applies for a slot from the free list, and arch_remove_kprobe returns a slot to the free list. The incorrect up()/down() orders to operate on kprobe_mutex fail to protect the free list. If 2 threads try to get/return kprobe instruction slot at the same time, the free slot list might be broken, or a free slot might be applied by 2 threads.

| | | | | | | | | | | | | | | | | | Revert commit 12ebcd73e40e09f0dfddf89e465cc0541e0ff8b1, i.e. [PATCH] uml: run mconsole "sysrq" in process context on request from Jeff Dike. a) sysrq may be run when the scheduler is non-functioning b) the warning I wanted to fix actually came from the fault handler run in atomic context. But I fixed that not to take the semaphore in a separate patch. c) the fault handler is run because of a fault, and that fault was unaffected by this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of doing byte-at-a-time user accesses to figure out where the fault occurred, read the saved fault_address from the current thread structure. For the sake of defensive programming, if the fault_address does not fall into the user buffer range, simply assume the whole area faulted. This will cause the fixup for copy_from_user() to clear the entire kernel side buffer. Signed-off-by: David S. Miller <davem@davemloft.net>
