commit b7f7d28b61a806f02e1f4cea81213027c088be8b

hppa: Fix _FPU_GETCW and _FPU_SETCW.
The following patch fixes both _FPU_GETCW and
_FPU_SETCW for hppa. The initial implementation was
flawed and not well tested. We failed to set cw,
and passed in the value of a register to fldd.
This patch fixes both of those errors and allows
the libm tests to pass without failure.
