[Pkg-lustre-maintainers] PAGE_SIZE usage in lustre and a debian fix.

[David Brown]

Okay PAGE_SIZE and friends isn't available for some arches in the
kernel, in fact the only architectures that PAGE_SIZE and friends are
available for code that isn't compiled with __KERNEL__ are i386, m32r,
ppc, s390, sh64, x86_64, so after trying to compile the debian
packages (which build the userspace components separate from the
kernel components) on ia64 it failed.

Attached is a patch to 'fix' the problem the first part of the patch
is what should be happening. The second part of the patch is a hack to
get the source to build for debian built ia64 kernels.
