Merge branch 'x86-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'x86-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
x86/agp: Fix agp_amd64_init() initialization with CONFIG_GART_IOMMU enabled
x86: SGI UV: Fix writes to led registers on remote uv hubs
x86, kmemcheck: Use KERN_WARNING for error reporting
x86: Use KERN_DEFAULT log-level in __show_regs()
x86, compress: Force i386 instructions for the decompressor
x86/amd-iommu: Fix initialization failure panic
dma-debug: Do not add notifier when dma debugging is disabled.
x86: Fix objdump version check in chkobjdump.awk for different formats.
Trivial conflicts in arch/x86/include/asm/uv/uv_hub.h due to me having
applied an earlier version of an SGI UV fix.
