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.
