Merge tag 'qcom-cleanup-for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/galak/linux-qcom into next/cleanup

Merge "General cleanups for MSM/QCOM for 3.15" from Kumar Gala:

Split of the multiplatform support for the Qualcomm SoCs into a mach-qcom
while we leave mach-msm as legacy support.  Also, some smp and device tree
related cleanups.

* tag 'qcom-cleanup-for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/galak/linux-qcom:
  ARM: qcom: Rename various msm prefixed functions to qcom
  clocksource: qcom: split building of legacy vs multiplatform support
  ARM: qcom: Split Qualcomm support into legacy and multiplatform
  clocksource: qcom: Move clocksource code out of mach-msm
  ARM: msm: kill off hotplug.c
  ARM: msm: Remove pen_release usage
  ARM: dts: msm: split out msm8660 and msm8960 soc into dts include
