Merge branch 'mdm9640_base' into 'msm-3.18'

Add initial syupport for the 32-bit ARM Qualcomm MDM9640 target.
This code is ported from the msm-3.10 kernel branch with necessary
fix-ups made for compatibility with the 3.18 kernel (such as, and
most notably, migration to a new pinctrl driver / bindings).

* mdm9640_base:
  ARM: gic: enclose gic_sgi_lock declaration with CONFIG_SMP ifdef
  ARM: dts: update memory cma reservations for mdm9640
  kernel/lib: add additional debug capabilites for data corruption
  ARM: dma-mapping: Allow highmem pages to not have a mapping
  defconfig: snapshot mdm9640 config
  arm: Add support for KERNEL_TEXT_RDONLY
  msm: rtb: Log the context id in the rtb
  tracing: ftrace events for user faults and undefined instructions
  Revert "ARM: dma-mapping: remove dmac_clean_range and dmac_inv_range"
  pinctrl: mdm9640: Add pinctrl driver for mdm9640
  clk: msm: enable acpuclock driver compilation for mdm9640
  clk: msm: clock-a7: rename zirc to MDM9640
  ARM: dts: msm: Declare stubs for /cpus and /soc nodes
  soc: snapshot idle-v7.S
  ARM: dts: msm: snapshot MDM9640 device tree files
  ARM: build correct dtbs to append to zImage
  msm: Move dts into a subdirectory
  arm: mach-msm: board-9640: remove support for early debug console
  sysctl: add cold_boot sysctl entry
  msm: 8x55: put reason for boot in procfs from SMEM
  ARM: decompressor: avoid speculative prefetch from protected regions
  arm: msm: snapshot MDM9x40 relevant files from msm-3.10
  arm: msm: drop the upstream kernel mach-msm code
  scripts: build_all: stop building mdm targets
