Merge branch 'late/fixes' into fixes

* late/fixes:
  ARM: OMAP2+: Fix unmet direct dependencies for SERIAL_OMAP
  ARM: ux500: always select ABX500_CORE
  ARM: SIRF: select SMP_ON_UP only on SMP builds
  ARM: SPEAr: conditionalize l2x0 support
  ARM: imx: build CPU suspend code only when needed
  ARM: OMAP: build SMP code only for OMAP4/5
  ARM: tegra: Tegra114 needs CPU_FREQ_TABLE
  ARM: default machine descriptor for multiplatform
