[PATCH] x86_64 early numa init fix

2005-09-30T19:41:20+00:00

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_cpumask

2005-09-30T19:41:20+00:00

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_64

2005-09-30T19:41:20+00:00

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.

Use of time_before() macro, defined at linux/jiffies.h, which deal with
wrapping correctly and are nicer to read.
