Hi, attached is a tarball containing a small series of patches, that apply on linux-2.6.13-rc5 + incremental patches from Jeff. Most of the patches are small fixes or they prepare UML for s390. The implementation is s390.patch Please read comments in the included series file and read comments in s390.patch about s390-host kernel versions that can be used to run UML on top of it. Currently SKAS0 can be used on a 2.6 kernel, while versions < 2.6.13-rc? might need two small patches, that also can be taken from the comments in s390.patch SKAS3 patches will follow later. Bodo
