[PATCH 2/3] x86/amd-iommu: Fix crash when request_mem_region fails
When request_mem_region fails the error path tries to disable the IOMMUs. This accesses the mmio-region which was not allocated leading to a kernel crash. This patch fixes the issue.

[PATCH 3/3] x86/amd-iommu: Fall back to GART if initialization fails
This patch implements a fallback to the GART IOMMU if this is possible and the AMD IOMMU initialization failed. Otherwise the fallback would be nommu which is very problematic on machines with more than 4GB of memory or swiotlb which hurts io-performance.

[PATCH 1/3] arch/x86/kernel: Add missing spin_unlock
From: Julia Lawall <julia(a)diku.dk> Add a spin_unlock missing on the error path. The locks and unlocks are balanced in other functions, so it seems that the same should be the case here. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1; @@ ... 1 Jun 2010 05:24

I am working on pxa300 based development board and using Linux 2.6.34. This Linux kernel already has support for following boards 1. zylonite_pxa300 2. cm-x300 3. colibri-pxa300 4. littleton My doubt is that pxa300 based boards are using "0xa0000000" as DDRAM base and PHYS_OFFSET is also defined in "arch/ar... 1 Jun 2010 05:24

[patch] btrfs: uninitialized data is check_path_shared()
refs can be used with uninitialized data if btrfs_lookup_extent_info() fails on the first pass through the loop. In the original code if that happens then check_path_shared() probably returns 1, but with this patch it will continue through the loop. I'm not super familiar with this code so please look it over ca... 1 Jun 2010 05:24
