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.
From comments on the LKML PAGE_SIZE shouldn't ever be used by
userspace and should be using getpagesize() and perform some functions
to get the other values (PAGE_MASK and PAGE_SHIFT).
Hopefully this helps,
