Log:
SVN rev 190426 on 2009-03-25 22:08:30Z by jhb
Fix a few nits in the earlier changes to prevent local information leakage
in AMD FPUs:
- Do not clear the affected state in the case that the FPU registers for
the thread that already owns the FPU are changed via fpu_setregs(). The
only local information the thread would see is its own state in that
case.
- Fix a type mismatch for the dummy variable used in a "fld". It accepts
a float, not a double.
