xfs/linux/Makefile.in

[Chris Wing]

I believe that the Linux kernel code may need to use different options to
compile correctly, namely a different compiler entirely is used on sparc64
(due to the fact that the kernel is a 64-bit binary but user programs are
32-bit), and on Alpha the compiler must be told to preserve certain
registers to work properly in the kernel. ('-ffixed-8')

Have you tried the patch on non-i386 architectures? I may be mistaken
about all this, though, I haven't looked at it that closely.
