gcc-4.2-hppa64 bug

[Kyle McMartin <kyle@mcmartin.ca>]

John et al,

We're currently hitting a gcc bug on hppa64 with both gcc-4.1 and
gcc-4.2. Symptoms are that a build of the ocfs2 module spins
(apparently) forever, I'm leaving a copy building to see if it
eventually makes forward progress.

It's pretty easily reproduceable by building a modular kernel with the
ocfs2 module enabled. Is there anything I can do to help narrow this
down?

make fs/ocfs2/ocfs2.ko:
	!SMP	SMP
32-bit	 y	 y
64-bit	 y	 fails

The troublesome source file appears to be fs/ocfs2/alloc.o, the rest
seem to build fine.

cheers,
	Kyle
