Bit me too. The "vdso=0" has me running 303 on an Athlon now. Glad to
see a Red Hat guy is puzzled also.
Google is NOT my friend on this - best I can find is that a vDSO is a
virtual DSO, has something to do with CPU features, and that the kernel
hackers have been talking about randomizing it, and trade-offs of
efficiency with security vulnerabilities quite a lot as of late. Please
enlighten us mere mortals.
