[uml-devel] SKAS-v8: RC2 released against 2.6.7 - 2.6.11-rc3-bk6 kernels

This time, I've announced this on my homepage, since I'd like to get some more testing. Things I've forgot: * make it apply easily on Fedora kernels. This should simply mean moving the TIF_SYSCALL_EMU to place no.8, to leave a slot free for _DB7, needed for 4g4g or something like that and using

Ok, the first thing is the cleanup of PTRACE_SYSEMU_SINGLESTEP. I've carefully moved the handling to go near to PTRACE_SINGLESTEP. As said, it's needed also to port this stuff to 2.6.10 easily (wrt the introduction of {clear,set}_singlestep). The patch is attached both with only my changes, to
