What is needed to provide spinlock support for linux on hppa?

Possibly nothing --- can you try CVS tip? Bruce has already committed
his patch to decouple CPU and OS assumptions there, and I changed the
TAS code to be inline for gcc. AFAICS it should just work.

I should add that 7.3.4 built OK.

For sufficiently small values of OK, perhaps so. We didn't complain
about not having spinlocks then.

I think it might be possible to develop a localized patch for 7.4 that
only affects linux-hppa and doesn't risk breaking anything else: copy
the slock_t definition for hppa from hpux.h into linux.h and add the
inline'd version of hppa tas() from CVS tip into s_lock.h. But I'm not
particularly interested in working on it at two removes from where any
testing could get done.

I think he also has to modify src/include/port/linux.h to support the HP
processor.

That's what I said, I thought.

Oh, I saw slock_t definition and thought s_lock.h.

I can't very easily get cvs tip built on linus-hppa, because I
couldn't make a package of that except for experimental, but
experimental doesn't get processed by the autobuilders.

Time to break out the old configure; make; make install...
