I've found the problem in general. It affects any 64-bit architecture. The problem occurs when you change the system time. Suppose that when you boot your system clock is forward by a day. This gets recorded down in skb_tv_base. You then wind the clock back by a day. From that point onwards the offset will be negative which essentially overflows the 32-bit variables they're stored in. In fact, why don't we just store the real time stamp in those 32-bit variables? After all, we're not going to overflow for quite a while yet. When we do overflow, we'll need a better solution of course. Signed-off-by:

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. Signed-off-by:

Some Legacy megaraid cards can't actually cope with the scatter/gather version of the READ CAPACITY command (which is what we now send them since altering all SCSI internal I/O to go via the block layer). Fix this (and a few other broken megaraid driver assumptions) by sending the non-sg version of the command if the sg list only has a single element.

In these drivers, scsi_remove_host() is called too late, at the point it is called, the driver has already shut down too far to accept any I/O that the shutdown might generate. Any generated I/O actually triggers a panic. Fix this by calling scsi_remove_host() as early as possible and not calling scsi_host_put() until just before we kfree the ahc_softc. Signed-off-by: -

There's a problem in our host release in that it calls scsi_proc_hostdir_rm(). However, if you hold a reference to the host as you remove the module, the host template (which proc uses) will be freed and the system will panic when the host device is finally released. Fix this by moving scsi_proc_hostdir_rm() to where it should be: in scsi_remove_host(). Signed-off-by: -

This adds the new iBook G4 (manufactured after July 2005) to the PowerMac models table. 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. Signed-off-by:

This adds suspend support for the Radeon M11 chip in 12" iBooks manufactured after July 2005. I don't know if the new 14" iBooks also have that chip, so they might also be supported. The chip identifies itself as "RV350 NV" (pci id 0x4e56), revision 0x80. Apple calls it "Snowy", xfree86 names it "ATI FireGL Mobility T2 (M11) NV (AGP)". So, we seem to be lucky here: The suspend-code for the M10 (which also is a "RV350 NV") works flawless for that chip. Signed-off-by:

We should always use bitmask ops, rather than depend on some ordering of the different states. With the TASK_NONINTERACTIVE flag, the inequality doesn't really work. Oleg Nesterov argues (likely correctly) that this test is unnecessary in the first place. However, the minimal fix for now is to at least make it work in the presense of TASK_NONINTERACTIVE. Waiting for consensus from Roland & co on potential bigger cleanups. Signed-off-by: -

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.

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.

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.

Zhang, Yanmin authored
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. Signed-off-by:

Set serialize_io=1 by default. This is safer and required by seemingly more and more hardware. It causes little or no performance loss for S400 devices. Performance of S800 1394b devices may drop by 25...30%. Therefore make the parameter's description and dmesg message clearer about performance impact. Update description of the max_speed parameter too. IEEE1394_SPEED_MAX is currently S800. Signed-off-by:

Fixes for deadlocks of the ieee1394 and scsi subsystems and long delays in futile error recovery attempts when SBP-2 devices are removed or drivers are unloaded. - Complete commands quickly with DID_NO_CONNECT if the 1394 node is gone or if the 1394 low-level driver was unloaded. - Skip unnecessary work in the eh_abort_handler and eh_device_reset_handler if the node or 1394 low-level driver is gone. - Let scsi's high-level shut down gracefully when sbp2 is being unloaded or detached from the 1394 unit. A call to scsi_remove_device is added for this purpose, which requires us to store a scsi_device pointer. - scsi_device pointer is obtained from slave_alloc hook and cleared by slave_destroy. This avoids usage of the pointer after the scsi device was deleted e.g. by the user via scsi_mod's sysfs interface. Signed-off-by:
