How do I install a kernel patch?
Unless otherwise mentioned, the content of a kernel patch is contained in an SAPCAR archive named dw_<nnn>-<xxx>.sar, where <nnn> is the patchlevel and <xxx> is some number. Installing a kernel patch simply means replacing files in the executable directory by their corresponding versions from the archive. It is important that all files contained in the archive are copied to the executable directory. Having different versions from different kernel patches in the executable directory might lead to serious runtime errors. It is important that subdirectories are replaced as well along with their corresponding content. It is recommended to make a backup of all files that are going to be replaced, as you may simply revert the kernel patch by installing the old files again later on.
