The eeepc_rfkill_hotplug() call from the resume handler is racing against the call from the ACPI notifier callback. The ACPI notification is triggered by the resume handler when it refreshes the value of CM_ASL_WLAN. The fix is to serialize hotplug calls using a workqueue. http://bugzilla.kernel.org/show_bug.cgi?id=13825 Signed-off-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Acked-by: Corentin Chary <corentin.chary@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some machines, a software-initiated SMI causes corruption unless the SMI runs on CPU 0. An SMI can be initiated by any AML, but typically it's done in GPE-related methods that are run via workqueues, so we can avoid the known corruption cases by binding the workqueues to CPU 0.

Symptoms of incorrect backlight mode selection are: 1. Non-working backlight control through sysfs; 2.

| | * | thinkpad-acpi: remove dock and bay subdriversHenrique de Moraes Holschuh2009-08-01

Userspace needs some love to support the two-stage ejection nicely, but it is simple enough to do through udev rules (you don't even need HAL) so this wouldn't justify fixing the dock and bay subdrivers, either. That leaves warm-swap bays (_EJ3) support for thinkpad-acpi, as well as support for the weird dock of the model 570, but since such support has never left the "experimental" stage, it is also not a strong enough reason to find a way to fix this code. Users of ThinkPads with warm-swap bays are urged to request that _EJ3 support be added to the regular ACPI dock driver, if such feature is indeed useful for them.

OTOH, the standard ACPI dock driver can handle the hotplug bays and docks of the ThinkPads just fine (including batteries) as of 2.6.27. In fact, it does a much better job of it than thinkpad-acpi ever did. It is just not worth the hassle to find a way to fix this crap without breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old, deprecated code that sees little testing or use. As a quick fix suitable for -stable backports, mark the thinkpad-acpi bay and dock subdrivers as BROKEN in Kconfig. The dead code will be removed by a later patch. This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

* | | Make pci_claim_resource() use request_resource() rather than insert_resource()Linus Torvalds2009-08-02

So there Matthew fixed it to actually look up the proper parent resource, which means that now it's actively wrong to then traverse the resource tree any more: we already know exactly where the new resource should go. And when we then did commit a76117dfd6 ("x86: Use pci_claim_resource"), which changed the x86 PCI code from the open-coded pr = pci_find_parent_resource(dev, r); if (!pr || request_resource(pr, r) < 0) { to using if (pci_claim_resource(dev, idx) < 0) { that "insert_resource()" now suddenly became a problem, and causes a regression covered by http://bugzilla.kernel.org/show_bug.cgi?id=13891 which this fixes.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ulrich Drepper correctly points out that there is generally padding in the structure on 64-bit hosts, and that copying the structure from kernel to user space can leak information from the kernel stack in those padding bytes. Avoid the whole issue by just copying the three members one by one instead, which also means that the function also can avoid the need for a stack frame. This also happens to match how we copy the new structure from user space, so it all even makes sense.

Chop it down to something reasonable, the number of slots in the caller's input buffer. If this is too large the caller may get ENOMEM but the reason should not be a mystery, and they can try again with something smaller. We add 1 to the value because in the normal getbmap world, bmv_count includes the header and xfs_getbmap does: nex = bmv->bmv_count - 1; if (nex <= 0) return XFS_ERROR(EINVAL); Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Olaf Weber <olaf@sgi.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Felix Blyakher <felixb@sgi.com>
