I checked the patches from patch 01 to 10 using ./scripts/checkpatch.pl under the kernel source directory, but got 0 errors and 0 warning. Only some white spaces in the cover letter 00, but is could not be checked by this script. But I checked the intel-iommu.c using "checkpatch.pl -f", found too many warnings and errors. Maybe we need a new patch to fix them.
