Linus Torvalds d8ea757b25 Xtensa improvements 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.
