Hi,
the radix tree headers don't compile:
xen/include/xen/radix-tree.h: In function 'radix_tree_int_to_ptr':
xen/include/xen/radix-tree.h:184: warning: comparison is always true due
to limited range of data type
xen/include/xen/radix-tree.h:184: warning: comparison is always true due
to limited range of data type
An 'int' is too small to hold a pointer.
C99 says 'uintptr_t' or 'intptr_t' is correct.
