I'd really like to get to:

#define malloc(sz)	kvmalloc(sz, GFP_KERNEL)
#define free(p)		kvfree(p)
#define realloc(p, sz)	kvrealloc(p, sz, GFP_KERNEL)	/* Doesn't exist yet */
#define calloc(n, sz)	kvmalloc_array(n, sz, GFP_KERNEL)

... or similar.  I wouldn't be surprised if we currently spend more I$
marshalling arguments for kvmalloc than we would spend exporting a new
malloc() function.
