Merge tag 'xtensa-20161005' of git://github.com/jcmvbkbc/linux-xtensa

Pull Xtensa updates from Max Filippov:
 "Updates for the xtensa architecture.  It is a combined set of patches
  for 4.8 that never got to the mainline and new patches for 4.9.

   - add new kernel memory layouts for MMUv3 cores: with 256MB and 512MB
     KSEG size, starting at physical address other than 0

   - make kernel load address configurable

   - clean up kernel memory layout macros

   - drop sysmem early allocator and switch to memblock

   - enable kmemleak and memory reservation from the device tree

   - wire up new syscalls: userfaultfd, membarrier, mlock2,
     copy_file_range, preadv2 and pwritev2

   - add new platform: Cadence Configurable System Platform (CSP) and
     new core variant for it: xt_lnx

   - rearrange CCOUNT calibration code, make most of it generic

   - improve machine reset code (XTFPGA now reboots reliably with MMUv3
     cores)

   - provide default memmap command line option for configurations
     without device tree support

   - ISS fixes: simdisk is now capable of using highmem pages, panic
     correctly terminates simulator"
