well, the devfs includes seem to depend on __KERNEL__ things, it solved
it on my box with the following hack (houuu, real ugly ;-)):

First, remove the -D__KERNEL__ from the Makefiles (of the lvm-tools of
cause!), then add this to $(KERN_SOURCES)/include/linux/lvm.h around the
include of linux/kdev_t.h (about line 90 or so):

/* KS : Look out! Following is a bad, bad hack solving compile problems
for tools! */
#if !defined (__KERNEL__)
#define  __KERNEL__ 1
#include <linux/kdev_t.h>
#undef __KERNEL__
#else
#include <linux/kdev_t.h>
#endif
#include <linux/major.h>
#include <asm/spinlock.h>

Works for, hope the same for you.

Bye
Klaus
