2009-12-16x86: uv: update XPC to handle updated BIOS interfaceRobin Holt
The UV BIOS has moved the location of some of their pointers to the "partition reserved page" from memory into a uv hub MMR. The GRU does not support bcopy operations from MMR space so we need to special case the MMR addresses using VLOAD operations. Additionally, the BIOS call for registering a message queue watchlist has removed the 'blade' value and eliminated the structure that was being passed in. This is also reflected in this patch.

2009-12-16x86: uv: introduce a means to translate from gpa -> socket_paddrRobin Holt
The UV BIOS has been updated to implement some of our interface functionality differently than originally expected. These patches update the kernel to the bios implementation and include a few minor bug fixes which prevent us from doing significant testing on real hardware. This patch: For SGI UV systems, translate from a global physical address back to a socket physical address. This does nothing to ensure the socket physical address is actually addressable by the kernel. That is the responsibility of the user of the function.

2009-12-15ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimizationAndres Salomon
Previously, OLPC support for the mic extensions was only enabled in the ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set. This was because the old geode GPIO code was written in a manner that assumed CONFIG_MGEODE_LX. With the new cs553x-gpio driver, this is no longer the case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead include a requirement on GPIOLIB. We use the generic GPIO API rather than the cs553x-specific API.

2009-12-15cs5535-gpio: add AMD CS5535/CS5536 GPIO driver supportAndres Salomon
This creates a CS5535/CS5536 GPIO driver which uses a gpio_chip backend (allowing GPIO users to use the generic GPIO API if desired) while also allowing architecture-specific users directly (via the cs5535_gpio_* functions). Tested on an OLPC machine. Some Leemotes also use CS5536 (with a mips cpu), which is why this is in drivers/gpio rather than arch/x86. Currently, it conflicts with older geode GPIO support; once MFGPT support is reworked to also be more generic, the older geode code will be removed.

2009-12-15x86: Split swiotlb initialization into two stagesFUJITA Tomonori
The commit f4780ca005404166cc40af77ef0e86132ab98a81 moves swiotlb initialization before dma32_free_bootmem(). It's supposed to fix a bug that the commit 75f1cdf1dda92cae037ec848ae63690d91913eac introduced, we initialize SWIOTLB right after dma32_free_bootmem so we wrongly steal memory area allocated for GART with broken BIOS earlier. However, the above commit introduced another problem, which likely breaks machines with huge amount of memory. Such a box use the majority of DMA32_ZONE so there is no memory for swiotlb. With this patch, the x86 IOMMU initialization sequence are: 1. We set swiotlb to 1 in the case of (max_pfn > MAX_DMA32_PFN && !no_iommu). If swiotlb usage is forced by the boot option, we go to the step 3 and finish (we don't try to detect IOMMUs). 2. We call the detection functions of all the IOMMUs. 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). 3. We initialize swiotlb (and set dma_ops to swiotlb_dma_ops) if swiotlb is set to 1. 4. If the IOMMU initialization function doesn't need swiotlb (e.g. the initialization is sucessful) then sets swiotlb to zero. 5. If we find that swiotlb is set to zero, we free swiotlb resource.

2009-12-11x86, msr: Add support for non-contiguous cpumasksBorislav Petkov
The current rd/wrmsr_on_cpus helpers assume that the supplied cpumasks are contiguous. However, there are machines out there like some K8 multinode Opterons which have a non-contiguous core enumeration on each node (e.g. cores 0,2 on node 0 instead of 0,1), see http://www.gossamer-threads.com/lists/linux/kernel/1160268. This patch fixes out-of-bounds writes (see URL above) by adding per-CPU msr structs which are used on the respective cores. Additionally, two helpers, msrs_{alloc,free}, are provided for use by the callers of the MSR accessors. Cc: H.

2009-12-11x86: Use find_e820() instead of hard coded trampoline addressYinghai Lu
Jens found the following crash/regression: [ 0.000000] found SMP MP-table at [ffff8800000fdd80] fdd80 [ 0.000000] Kernel panic - not syncing: Overlapping early reservations 12-f011 MP-table mpc to 0-fff BIOS data page and [ 0.000000] Kernel panic - not syncing: Overlapping early reservations 12-f011 MP-table mpc to 6000-7fff TRAMPOLINE and bisected it to b24c2a9 ("x86: Move find_smp_config() earlier and avoid bootmem usage"). It turns out the BIOS is using the first 64k for mptable, without reserving it. So try to find good range for the real-mode trampoline instead of hard coding it, in case some bios tries to use that range for sth.

2009-12-10x86/amd-iommu: Fix PCI hotplug with passthrough modeJoerg Roedel
The device change notifier is initialized in the dma_ops initialization path. But this path is never executed for iommu=pt. Move the notifier initialization to IOMMU hardware init code to fix this. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-12-10x86/amd-iommu: Fix passthrough modeJoerg Roedel
The data structure changes to use dev->archdata.iommu field broke the iommu=pt mode because in this case the dev->archdata.iommu was left uninitialized. This moves the inititalization of the devices into the main init function and fixes the problem. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
