Linus Torvalds de399813b5 powerpc updates for 4.10
Highlights include:
 
  - Support for the kexec_file_load() syscall, which is a prereq for secure and
    trusted boot.
 
  - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
 
  - Sort the exception tables at build time, to save time at boot, and store
    them as relative offsets to save space in the kernel image & memory.
 
  - Allow building the kernel with thin archives, which should allow us to build
    an allyesconfig once some other fixes land.
 
  - Build fixes to allow us to correctly rebuild when changing the kernel endian
    from big to little or vice versa.
 
  - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
 
  - Initial stack protector support (-fstack-protector).
 
  - Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
 
  - Fix an oops in cxl coredump generation when cxl_get_fd() is used.
 
  - Freescale updates from Scott: "Highlights include 8xx hugepage support,
    qbman fixes/cleanup, device tree updates, and some misc cleanup."
 
  - Many and varied fixes and minor enhancements as always.

# Makefile for making ELF bootable images for booting on CHRP
# using Open Firmware.
#
# Geert Uytterhoeven September 1997
#
# Based on coffboot by Paul Mackerras
# Simplified for ppc64 by Todd Inglett
#
# NOTE: this code is built for 32 bit in ELF32 format even though
# it packages a 64 bit kernel. We do this to simplify the
# bootloader and increase compatibility with OpenFirmware.
#
# To this end we need to define BOOTCC, etc, as the tools
# needed to build the 32 bit image. That's normally the same
# compiler for the rest of the kernel, with the -m32 flag added.
# To make it easier to setup a cross compiler,
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
# in the toplevel makefile.
