| * [IA64] Avoid kernel hang during CMC interrupt stormBryan Sutula2005-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've noticed a kernel hang during a storm of CMC interrupts, which was tracked down to the continual execution of the interrupt handler. There's code in the CMC handler that's supposed to disable CMC interrupts and switch to polling mode when it sees a bunch of CMCs. Because disabling CMCs across all CPUs isn't safe in interrupt context, the disable is done with a schedule_work(). But with continual CMC interrupts, the schedule_work() never gets executed. The following patch immediately disables CMC interrupts for the current CPU. This then allows (at least) one CPU to ignore CMC interrupts, execute the schedule_work() code, and disable CMC interrupts on the rest of the CPUs.

| * | [SPARC64]: Fix initrd when net booting.David S. Miller2005-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By allocating early memory for the firmware page tables, we can write over the beginning of the initrd image. So what we do now is: 1) Read in firmware translations table while still on the firmware's trap table. 2) Switch to Linux trap table. 3) Init bootmem. 4) Build firmware page tables using __alloc_bootmem(). And this keeps the initrd from being clobbered. Signed-off-by: David S. Miller <davem@davemloft.net>

* | | [PATCH] ppc: Fix timekeeping with HZ=250 on some Mac modelsBenjamin Herrenschmidt2005-10-05
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Older Macs which uses the VIA chip timers to calibrate the timebase used some code that wouldn't work if HZ wasn't divisible by 100... This fixes it at least for 250. Not totally perfect but should be enough for now (so it at least works with the default value which is now 250). There is still a potential issue with the core using CLOCK_TICK_RATE to maintain xtime and CLOCK_TICK_RATE value on ppc32 is pure crap, but that is a different problem, this patch at least brings us back to our previous situation.

This fixes a race condition with early start of udev, originally tracked down by Suresh B. Siddha.

| | | | | | | | | | | | | | | 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.

* [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.
