--- Comment #20 from Craig stein12c@gmail.com --- ok when i type the following it is unable to find the file to patch:

sudo patch -p1 < iommu-amd-flush-IOTLB-for-specific-domains-only.patch

It displays the following:

can't find file to patch at input line 5 Perhaps you used the wrong -p or --strip option?
