The 2.6.25-rc1 kernel build fails on the powerpc with the error

drivers/net/mlx4/alloc.c: In function ‘mlx4_buf_alloc’:
drivers/net/mlx4/alloc.c:162: error: implicit declaration of function ‘vmap’
drivers/net/mlx4/alloc.c:162: error: ‘VM_MAP’ undeclared (first use in this function)
drivers/net/mlx4/alloc.c:162: error: (Each undeclared identifier is reported only once
drivers/net/mlx4/alloc.c:162: error: for each function it appears in.)
drivers/net/mlx4/alloc.c:162: warning: assignment makes pointer from integer without a cast
drivers/net/mlx4/alloc.c: In function ‘mlx4_buf_free’:
drivers/net/mlx4/alloc.c:187: error: implicit declaration of function ‘vunmap’
make[3]: *** [drivers/net/mlx4/alloc.o] Error 1
make[2]: *** [drivers/net/mlx4] Error 2
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2

I have tested the patch for the build failure.
