block/scsi_ioctl.c: Remove debug regarding SCSI ioctls (also removed from later kernels).
drivers/net/fec.c: Reduce Ethernet FIFO RSEM threshold to 1 on iMX6 Rev 1.0 silicon. Reduces overruns by sending Pause frames much more readily than Boundary's setting (0x10) and Freescale's setting (0x84). Attempts to work around major overrun issue with iMX6 Gigabit ENET hardware block but some Ethernet overrurns still occur.
