If so, MFC0 and REG_S should be controlled by __mips64 (or
CONFIG_MIPS64) as you and Maciej W. Rozycki said in other mails.  I
wonder why currently is not.  Historical reason ? :-)

Now I'm looking 2.6 codes and there is same problem.  But 2.6 codes
does not use REG_S at all so the stack corruption will never happen.
FYI.
