Subject: [PATCH] Enable dt(4) on amd64, arm64, i386, and powerpc64 in GENERIC
 kernel. Support to skip frames is missing on arm64 and i386, but the stack
 traces are useful anyway.  sparc64 should work, but I could not test it. 
 Other architectures do not have stacktrace_save_at() and dynamic tracer does
 not link. from patrick@; OK semarie@
