Use defconfig and boot it. If you break ptrace, I think it's overwhelmingly likely that UML will stop booting. So if UML boots, I'd say you're good to go, with one caveat. That is, UML should report at boot that PTRACE_SYSEMU works. I put in a fallback from PTRACE_SYSEMU to PTRACE_SYSCALL when Fedora broke PTRACE_SYSEMU. > Right now (before these), UML > doesn't build for x86_64 or i386 from this tree to begin with. For current -mm, you'll need http://marc.info/?l=linux-kernel&m=119635496908681&q=raw to build.
