Clear the floating point exception flag before returning to user space. This is needed, else the libc trampoline handler may hit the same SIGFPE again while building up a trampoline to a signal handler. Fixes debian bug #559406.

README
All files except driver.c are snapshots from the HP-UX kernel. They've been modified as little as possible. Even though they don't fit the Linux coding style, please leave them in their funny format just in case someone in the future, with access to HP-UX source code, is generous enough to update our copies with later changes from HP-UX -- it'll make their 'diff' job easier if our code is relatively unmodified. Required Disclaimer: Hewlett-Packard makes no implied or expressed warranties about this code nor any promises to maintain or test it in any way. This copy of this snapshot is no longer the property of Hewlett-Packard.
