Merge branch 'fixes' into next/cleanup

Merging in fixes since there's a conflict in the omap4 clock tables caused by
it.

* fixes: (245 commits)
  ARM: highbank: fix cache flush ordering for cpu hotplug
  ARM: OMAP4: hwmod data: make 'ocp2scp_usb_phy_phy_48m" as the main clock
  arm: mvebu: Fix the irq map function in SMP mode
  Fix GE0/GE1 init on ix2-200 as GE0 has no PHY
  ARM: S3C24XX: Fix interrupt pending register offset of the EINT controller
  ARM: S3C24XX: Correct NR_IRQS definition for s3c2440
  ARM i.MX6: Fix ldb_di clock selection
  ARM: imx: provide twd clock lookup from device tree
  ARM: imx35 Bugfix admux clock
  ARM: clk-imx35: Bugfix iomux clock
  + Linux 3.9-rc6
