2009-11-10x86: Handle HW IOMMU initialization failure gracefullyFUJITA Tomonori
If HW IOMMU initialization fails (Intel VT-d often does this, typically due to BIOS bugs), we fall back to nommu. It doesn't work for the majority since nowadays we have more than 4GB memory so we must use swiotlb instead of nommu. The problem is that it's too late to initialize swiotlb when HW IOMMU initialization fails. We need to allocate swiotlb memory earlier from bootmem allocator. Chris explained the issue in detail: http://marc.info/?l=linux-kernel&m=125657444317079&w=2 The current x86 IOMMU initialization sequence is too complicated and handling the above issue makes it more hacky. This patch changes x86 IOMMU initialization sequence to handle the above issue cleanly. The new x86 IOMMU initialization sequence are: 1. we initialize the swiotlb (and setting swiotlb to 1) in the case of (max_pfn > MAX_DMA32_PFN && !no_iommu). dma_ops is set to swiotlb_dma_ops or nommu_dma_ops. if swiotlb usage is forced by the boot option, we finish here. 2. we call the detection functions of all the IOMMUs 3. the detection function sets x86_init.iommu.iommu_init to the IOMMU initialization function (so we can avoid calling the initialization functions of all the IOMMUs needlessly). 4. if the IOMMU initialization function doesn't need to swiotlb then sets swiotlb to zero (e.g. the initialization is sucessful). 5. if we find that swiotlb is set to zero, we free swiotlb resource.

Not a single line of actual code in the function was really fundamentally correct. Problems ranged from lack of proper range checking, to removing the last character written (which admittedly is usually '\n'), to not accepting hex numbers even though the 'show' routine would show the data in that format. This tries to do better.

Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c (PM / yenta: Fix cardbus suspend/resume regression) caused resume to fail on systems with two CardBus bridges. While the exact nature of the failure is not known at the moment, it can be worked around by splitting the yenta resume into an early part, executed during the early phase of resume, that will only resume the socket and power it up if there was a card in it during suspend, and a late part, executed during "regular" resume, that will carry out all of the remaining yenta resume operations.

2009-11-02i915: fix intel graphics suspend breakage due to resume/lid event confusionLinus Torvalds
In commit c1c7af60892070e4b82ad63bbfb95ae745056de0 ("drm/i915: force mode set at lid open time") the intel graphics driver was taught to restore the LVDS mode on lid open. That caused problems with interaction with the suspend/resume code, which commonly runs at the same time (suspend is often caused by the lid close event, while lid open is commonly a resume event), which was worked around with in commit 06891e27a9b5dba5268bb80e41a283f51335afe7 ("drm/i915: fix suspend/resume breakage in lid notifier"). However, in the meantime the lid event code had also grown a user event notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915: generate a KMS uevent at lid open/close time"), and now _that_ causes problems with suspend/resume and some versions of Xorg reacting to those uevents by setting the mode. So this effectively reverts that commit 06324194ee, and makes the lid open protection logic against suspend/resume more explicit. This fixes at least one laptop. See http://bugzilla.kernel.org/show_bug.cgi?id=14484 for more details.

The MTU throttle-down if a RNDIS device doesn't support a particular packet size is being incorrectly logged. The attempted packet size is being clobbered before it gets logged. First patch; please inform if I'm doing this incorrectly. Diff'd against latest official source as per the FAQ; forward port to current git version is straightforward.

It's causing lots of build errors, so just mark it as broken. It is scheduled to be removed in 2.6.33 anyway. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-10-30Staging: remove stlc45xx driverGreg Kroah-Hartman
It's no longer needed as the p54spi driver is the same thing, under a different name and in the correct portion of the kernel tree. Cc: Javier Martinez Canillas <martinez.javier@gmail.com> Cc: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
