Doing something like this on a two cpu system # echo 0 > /sys/devices/system/cpu/cpu0/online # echo 1 > /sys/devices/system/cpu/cpu0/online # echo 0 > /sys/devices/system/cpu/cpu1/online will give me this: ======================================================= [ INFO: possible circular locking dependency detected ] 2.6.21-rc2-g562aa1d4-dirty #7 ------------------------------------------------------- bash/1282 is trying to acquire lock: (&cpu_base->lock_key){.+..}, at: [<000000000005f17e>] hrtimer_cpu_notify+0xc6/0x240 but task is already holding lock: (&cpu_base->lock_key#2){.+..}, at: [<000000000005f174>] hrtimer_cpu_notify+0xbc/0x240 which lock already depends on the new lock. This happens because we have the following code in kernel/hrtimer.c: migrate_hrtimers(int cpu) [...] old_base = &per_cpu(hrtimer_bases, cpu); new_base = &get_cpu_var(hrtimer_bases); [...] spin_lock(&new_base->lock); spin_lock(&old_base->lock); Which means the spinlocks are taken in an order which depends on which cpu gets shut down from which other cpu. Therefore lockdep complains that there might be an ABBA deadlock. Since migrate_hrtimers() gets only called on cpu hotplug it's safe to assume that it isn't executed concurrently on a The same problem exists in kernel/timer.c: migrate_timers(). As pointed out by Christian Borntraeger one possible solution to avoid the locking order complaints would be to make sure that the locks are always taken in the same order. E.g. by taking the lock of the cpu with the lower number first. To achieve this we introduce two new spinlock functions double_spin_lock and double_spin_unlock which lock or unlock two locks in a given order.

This patch resolves the issue found here: http://bugme.osdl.org/show_bug.cgi?id=7426 The basic summary is: Currently we register most of i386/x86_64 clocksources at module_init time. Then we enable clocksource selection at late_initcall time. This causes some problems for drivers that use gettimeofday for init calibration routines (specifically the es1968 driver in this case), where durring module_init, the only clocksource available is the low-res jiffies clocksource. This may cause slight calibration errors, due to the small sampling time used. It should be noted that drivers that require fine grained time may not function on architectures that do not have better then jiffies resolution timekeeping (there are a few). However, this does not discount the reasonable need for such fine-grained timekeeping at init time. Thus the solution here is to register clocksources earlier (ideally when the hardware is being initialized), and then we enable clocksource selection at fs_initcall (before device_initcall). This patch should probably get some testing time in -mm, since clocksource selection is one of the most important issues for correct timekeeping, and I've only been able to test this on a few of my own boxes.

Recent patch for raid6 reshape had a change missing that showed up in subsequent review. Many places in the raid5 code used "conf->raid_disks-1" to mean "number of data disks". With raid6 that had to be changed to "conf->raid_disk - conf->max_degraded" or similar. One place was missed. This bug means that if a raid6 reshape were aborted in the middle the recorded position would be wrong. On restart it would either fail (as the position wasn't on an appropriate boundary) or would leave a section of the array unreshaped, causing data corruption. Signed-off-by:

Use para_fill instead of directly setting the APIC ops to the result of the vmi_get_function call - this allows one to implement a VMI ROM without implementing APIC functions, just using the native APIC functions. While doing this, I realized that there is a lot more cleanup that should have been done. Basically, we should never assume that the ROM implements a specific set of functions, and always allow fallback to the native implementation. This is critical for future compatibility.

More goo from hrtimers integration. We do compile and run properly with NO_HZ enabled. There was a period when we didn't because of a missing export, but that was since fixed. And with the clocksource code now firmly in place, we can get rid of code that fixes up the wallclock, since this is done in the common infrastructure. This actually fixes a timer bug as well, that was caused by do_settimeofday no longer being callable with interrupts disabled due to the use of on_each_cpu(). Signed-off-by:

The time_init_hook in paravirt-ops no longer functions in the correct manner after the integration of the hrtimers code. The problem is that now the call path for time initialization is: time_init : late_time_init = hpet_time_init; late_time_init -> hpet_time_init: setup_pit_timer (BAD) do_time_init --> (via paravirt.h) time_init_hook --> (via arch_hooks.h) time_init_hook (in SUBARCH/setup.c) If this isn't confusing enough, the paravirt case goes through an indirect function pointer in the paravirt-ops table. The problem is, by the time the paravirt hook is called, the pit timer is already enabled. But paravirt guests have their own timer, and don't want to use the PIT. Rather than intensify the struggle for power going on here, just make it all nice and simple and just unconditionally do all timer setup in the late_time_init hook. This also has the advantage of enabling timers in the same place in all code paths, so everyone has the same bugs and we don't have outliers who break other code because they turn on timer too early or too late. So the paravirt-ops time init function is now by default hpet_time_init, which is the time init function used for native hardware. Paravirt guests have the chance to override this when they setup the paravirt-ops table, and should need no change. Signed-off-by: -

Not respecting udelay causes problems with any virtual hardware that is passed through to real hardware. This can be noticed by any device that interacts with the real world in real time - like AP startup, which takes real time. Or keyboard LEDs, which should blink in real-time. Or floppy drives, but only when passed through to a real floppy controller on OSes which can't sufficiently buffer the floppy commands to emulate a zero latency floppy. Or IDE drives, when connecting to a physical CDROM. This was mostly a hack to get the kernel to boot faster, but it introduced a number of misvirtualization bugs, and Alan and Pavel argued pretty strongly against it. We were the only client, and now want to clean up this cruft. Signed-off-by:

Provide a PT map hook for HIGHPTE kernels to designate where they are mapping page tables. This information is required so the physical address of PTE updates can be determined; otherwise, the mm layer would have to carry the physical address all the way to each PTE modification callsite, which is even more hideous that the macros required to provide the proper hooks. So lets not mess up arch neutral code to achieve this, but keep the horror in an #ifdef HIGHPTE in include/asm-i386/pgtable.h. I had to use macros here because some types are not yet defined in all the include paths for this header. This patch is absolutely required for HIGHPTE kernels to operate properly with VMI.

In order to share the common code in tsc.c which does CPU Khz calibration, we need to make an accurate value of CPU speed available to the tsc.c code. This value loses a lot of precision in a VM because of the timing differences with real hardware, but we need it to be as precise as possible so the guest can make accurate time calculations with the cycle counters.

The custom_sched_clock hook is broken. The result from sched_clock needs to be in nanoseconds, not in CPU cycles. The TSC is insufficient for this purpose, because TSC is poorly defined in a virtual environment, and mostly represents real world time instead of scheduled process time (which can be interrupted without notice when a virtual machine is descheduled). To make the scheduler consistent, we must expose a different nature of time, that is scheduled time. So deprecate this custom_sched_clock hack and turn it into a paravirt-op, as it should have been all along. This allows the tsc.c code which converts cycles to nanoseconds to be shared by all paravirt-ops backends. It is unfortunate to add a new paravirt-op, but this is a very distinct abstraction which is clearly different for all virtual machine implementations, and it gets rid of an ugly indirect function which I ashamedly admit I hacked in to try to get this to work earlier, and then even got in the wrong units.

Critical bugfixes for the VMI-Timer code. 1) Do not setup a one shot alarm if we are keeping the periodic alarm armed. Additionally, since the periodic alarm can be run at a lower rate than HZ, let's fixup the guard to the no-idle-hz mode appropriately. This fixes the bug where the no-idle-hz mode might have a higher interrupt rate than the non-idle case. 2) The interrupt handler can no longer adjust xtime due to nested lock acquisition. Drop this. We don't need to check for wallclock time at every tick, it can be done in userspace instead. 3) Add a bypass to disable noidle operation. This is useful as a last minute workaround, or testing measure. 4) The code to skip the IO_APIC timer testing (no_timer_check) should be conditional on IO_APIC, not SMP, since UP kernels can have this configured in as well.

Currently we do not check for vma flags if sys_move_pages is called to move individual pages. If sys_migrate_pages is called to move pages then we check for vm_flags that indicate a non migratable vma but that still includes VM_LOCKED and we can migrate mlocked pages. Extract the vma_migratable check from mm/mempolicy.c, fix it and put it into migrate.h so that is can be used from both locations. Problem was spotted by Lee Schermerhorn Signed-off-by:

Currently sm501fb_crtsrc_store() won't allow the routing to be changed via echos from userspace in to the sysfs file. The reason for this is that the strnicmp() for both heads uses a sizeof() for the string length, which ends up being strlen() + 1 (\0 in the normal case, but the echo gives a newline, which is where the issue occurs), this then causes a mismatch and subsequently bails with the -EINVAL. In addition to this, the hardcoded lengths were then used for the store length that was returned, which ended up being erroneous and resulting in a write error. There's also no point in returning anything but the full length since it will -EINVAL out on a mismatch well before then anyways. sizeof("string") is great for making sure you have space in your buffer, but rather less so for string comparisons :-) Signed-off-by:Paul Mundt <lethal@linux-sh.org> Acked-by:

Remove the SMT-nice feature which idles sibling cpus on SMT cpus to facilitiate nice working properly where cpu power is shared. The idling of cpus in the presence of runnable tasks is considered too fragile, easy to break with outside code, and the complexity of managing this system if an architecture comes along with many logical cores sharing cpu power will be unworkable. Remove the associated per_cpu_gain variable in sched_domains used only by this code. Also: The reason is that with dynticks enabled, this code breaks without yet further tweaks so dynticks brought on the rapid demise of this code. So either we tweak this code or kill it off entirely. It was Ingo's preference to kill it off. Either way this needs to happen for 2.6.21 since dynticks has gone in. Signed-off-by:

Most drivers using GPIOs already know they are running on a system that supports the generic GPIO calls, because of other platform dependencies. But the generic GPIO-based LED and input button drivers can't know that. So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms where <asm/gpio.h> will do the right thing. Currently that's a bunch of ARMs, and AVR32; more are on the way. It also fixes a dependency bug for the gpio button input driver; it was wrong to start with, now it covers all platforms with GENERIC_GPIO. Signed-off-by:

Fix soft lockup with iSeries viocd driver, caused by eventually calling end_that_request_first() with nr_bytes 0. Some versions of hald do an SG_IO ioctl on the viocd device which becomes a request with hard_nr_sectors and hard_cur_sectors set to zero. Passing zero as the number of sectors to end_request() (which calls end_that_request_first()) causes an infinite loop when the bio is being freed. This patch makes sure that the zero is never passed. It only requires some number larger the the request size the terminate the loop. The lockup is triggered by hald, interrogating the device. Signed-off-by:

For devices that do not support msi-x we only support 1 interrupt. Therefore we can disable that one interrupt by disabling the msi capability itself. If we leave the intx interrupts disabled while we have the msi capability disabled no interrupts should be delivered from that device. Devices with just the minimal msi support (and thus hitting this code path) include things like the intel e1000 nic, so it looks like is going to be a fairly common case and thus important to get right.

enable/disable_msi_mode have several side effects which keeps them from being generally useful. So this patch replaces them with with two much more targeted functions: msi_set_enable and msix_set_enable. This patch makes pci_dev->msi_enabled and pci_dev->msix_enabled the definitive way to test if linux has enabled the msi capability, and has the appropriate msi data structures set up. This patch ensures that while writing the msi messages in save/restore and during device initialization we have the msi capability disabled so we don't get into races. The pci spec requires that we do not have the msi capability enabled and the msi messages unmasked while we write the messages. Completely disabling the capability is overkill but it is easy :) Care has been taken so we never have both a msi capability and intx enabled simultaneously. We haven't run into a problem yet but better safe then sorry. Signed-off-by:

In some cases when we are not using msi we need a way to ensure that the hardware does not have an msi capability enabled. Currently the code has been calling disable_msi_mode to try and achieve that. However disable_msi_mode has several other side effects and is only available when msi support is compiled in so it isn't really appropriate. Instead this patch implements pci_msi_off which disables all msi and msix capabilities unconditionally with no additional side effects. pci_disable_device was redundantly clearing the bus master enable flag and clearing the msi enable bit. A device that is not allowed to perform bus mastering operations cannot generate intx or msi interrupt messages as those are essentially a special case of dma, and require bus mastering. So the call in pci_disable_device to disable msi capabilities was redundant. quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off. Signed-off-by:
