* [PATCH] Fix misrouted interrupts deadlocksPavel Emelianov2006-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While testing kernel on machine with "irqpoll" option I've caught such a lockup: __do_IRQ() spin_lock(&desc->lock); desc->chip->ack(); /* IRQ is ACKed */ note_interrupt() misrouted_irq() handle_IRQ_event() if (...) local_irq_enable_in_hardirq(); /* interrupts are enabled from now */ ... __do_IRQ() /* same IRQ we've started from */ spin_lock(&desc->lock); /* LOCKUP */ Looking at misrouted_irq() code I've found that a potential deadlock like this can also take place: 1CPU: __do_IRQ() spin_lock(&desc->lock); /* irq = A */ misrouted_irq() for (i = 1; i < NR_IRQS; i++) { spin_lock(&desc->lock); /* irq = B */ if (desc->status & IRQ_INPROGRESS) { 2CPU: __do_IRQ() spin_lock(&desc->lock); /* irq = B */ misrouted_irq() for (i = 1; i < NR_IRQS; i++) { spin_lock(&desc->lock); /* irq = A */ if (desc->status & IRQ_INPROGRESS) { As the second lock on both CPUs is taken before checking that this irq is being handled in another processor this may cause a deadlock. This issue is only theoretical. I propose the attached patch to fix booth problems: when trying to handle misrouted IRQ active desc->lock may be unlocked.

* [PATCH] pci: don't try to remove sysfs files before they are setup.David Miller2006-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PCI sysfs attributes are created after the initial PCI bus scan. With the addition of more return value checking and assertions in the device and sysfs layers we now can get dumps like this on sparc64: [ 20.135032] Call Trace: [ 20.135042] [0000000000537f88] pci_remove_bus_device+0x30/0xc0 [ 20.135076] [000000000078f890] pci_fill_in_pbm_cookies+0x98/0x440 [ 20.135109] [000000000042e828] sabre_scan_bus+0x230/0x400 [ 20.135139] [000000000078c710] pcibios_init+0x58/0xa0 [ 20.135159] [0000000000416f14] init+0x9c/0x2e0 [ 20.135190] [0000000000417a50] kernel_thread+0x38/0x60 [ 20.135211] [0000000000417170] rest_init+0x18/0x40 [ 20.135514] PCI0(PBMB): Bus running at 33MHz It's triggering because removal of the "config" PCI sysfs file for the device fails. On sparc64, after probing the device, we'll delete the PCI device via pci_remove_bus_device() if we cannot find the firmware device tree node corresponding to it. This is fine, but at this point the sysfs files for the PCI device won't be setup yet. So we should not try to do anything in pci_remove_sysfs_dev_files() if pci_sysfs_init() has not run yet.

* [PATCH] htirq: refactor so we only have one function that writes to the chipEric W. Biederman2006-11-08
| | | | | | | | | | | | | | | | | | | | | This refactoring actually optimizes the code a little by caching the value that we think the device is programmed with instead of reading it back from the hardware. Which simplifies the code a little and should speed things up a bit. This patch introduces the concept of a ht_irq_msg and modifies the architecture read/write routines to update this code. There is a minor consistency fix here as well as x86_64 forgot to initialize the htirq as masked. Signed-off-by: Eric W.

* [PATCH] sysctl: Undeprecate sys_sysctlEric W. Biederman2006-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic issue is that despite have been deprecated and warned about as a very bad thing in the man pages since its inception there are a few real users of sys_sysctl. It was my assumption that because sysctl had been deprecated for all of 2.6 there would be no user space users by this point, so I initially gave sys_sysctl a very short deprecation period. Now that I know there are a few real users the only sane way to proceed with deprecation is to push the time limit out to a year or two work and work with distributions that have big testing pools like fedora core to find these last remaining users. Which means that the sys_sysctl interface needs to be maintained in the meantime. Since I have provided a technical measure that allows us to add new sysctl entries without reserving more binary numbers I believe that is enough to fix the sys_sysctl binary interface maintenance problems, because there is no longer a need to change the binary interface at all. Since the sys_sysctl implementation needs to stay around for a while and the worst of the maintenance issues that caused us to occasionally break the ABI have been addressed I don't see any advantage in continuing with the removal of sys_sysctl. So instead of merely increasing the deprecation period this patch removes the deprecation of sys_sysctl and modifies the kernel to compile the code in by default. With committing to maintain sys_sysctl we get all of the advantages of a fast interface for anything that needs it. Currently sys_sysctl is about 5x faster than /proc/sys, for the same string data.

The only open question is whether there is a better way of getting there. Perhaps with less configuration options in the first place? We are heading towards a future where so many systems will be NUMA that there would seem to be little benefit in keeping ACPI_NUMA separate from ACPI ... but perhaps we aren't quite there yet.

* [PATCH] md: do not freeze md threads for suspendRafael J. Wysocki2006-11-08
| | | | | | | | | | | | | | | | If there's a swap file on a software RAID, it should be possible to use this file for saving the swsusp's suspend image. Also, this file should be available to the memory management subsystem when memory is being freed before the suspend image is created. For the above reasons it seems that md_threads should not be frozen during the suspend and the appended patch makes this happen, but then there is the question if they don't cause any data to be written to disks after the suspend image has been created, provided that all filesystems are frozen at that time.

| | | | | | | | | | | | | | | | | | | | There is a race between dev_create() and find_device(). If the mdptr has not yet been stored against a device, find_device() needs to behave as though no device was found. It already returns NULL, but there is a dm_put() missing: it must drop the reference dm_get_md() took. The bug was introduced by dm-fix-mapped-device-ref-counting.patch. It manifests itself if another dm ioctl attempts to reference a newly-created device while the device creation ioctl is still running. The consequence is that the device cannot be removed until the machine is rebooted. Certain udev configurations can lead to this happening.

* [PATCH] Regression in 2.6.19-rc microcode driverArjan van de Ven2006-11-08
| | | | | | | | | | | | | | | | | | | | If the microcode driver is built in (rather than module) there are some, ehm, interesting effects happening due to the new "call out to userspace" behavior that is introduced.. and which runs too early. The result is a boot hang; which is really nasty. The patch below is a minimally safe patch to fix this regression for 2.6.19 by just not requesting actual microcode updates during early boot. (That is a good idea in general anyway) The "real" fix is a lot more complex given the entire cpu hotplug scenario (during cpu hotplug you normally need to load the microcode as well); but the interactions for that are just really messy at this point; this fix at least makes it work and avoids a full detangle of hotplug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the x86-64 version of f9dadfa71bc594df09044da61d1c72701121d802 that did the same thing on i386. Since the "mask" bit is in the low word, when we write a new entry, we need to write the high word first, before we potentially unmask it. The exception is when we actually want to mask the interrupt, in which case we want to write the low word first to make sure that the high word doesn't change while the interrupt routing is still active.

| * x86-64: clean up io-apic accessesLinus Torvalds2006-11-08
| | | | | | | | | | | | | | | | | | | | | | | | This is just commit 130fe05dbc0114609cfef9815c0c5580b42decfa ported to x86-64, for all the same reasons. It cleans up the IO-APIC accesses in order to then fix the ordering issues. We move the accessor functions (that were only used by io_apic.c) out of a header file, and use proper memory-mapped accesses rather than making up our own "volatile" pointers.

* | Revert "[PATCH] i386: Add MMCFG resources to i386 too"Linus Torvalds2006-11-08
|/ | | | | | | | | | | | This reverts commit de09bddb9d6f96785be470c832b881e6d72d589f. It tried to reserve the MMCONFIG mmio memory ranges, but since the MMCONFIG information is broken and often bogus (which is why we don't dare use it most of the time _anyway_), it does more harm than good.
