Subject: Re: [PATCH linux-next] ARM: imx: fix imx_init_l2cache storage class

Vincent,

Sorry.  I was not aware of that imx_v6_v7_defconfig does not have
CACHE_L2X0 enabled, so I did not catch it with my testing.  Thanks for
fixing it.

The commit ID is not stable, and I dropped it and applied the patch.
