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.

There are multiple occurences of both contextB and context_b
in different h/w descriptors, referring to the same descriptor
field known as "Context B". Stick with the "context_b" naming,
for obvious reasons including consistency (see also context_a).

1. qm_mcc_querywq layout not used for now, so drop it;
2. queryfq, queryfq_np and alterfq are used only for accesses to
the 'fqid' field, so replace these with a generic 'fq' layout.
As a consequence, 'querycgr' turns into 'cgr' following the
same reasoning above and for consistent naming.

Replace dummy platform device hack with a reference to a portal's
platform device, in order to dma map the test frame for this
small unit test. The 2 qman symbols need to be exported because
this self test is a kernel module.

Signed-off-by: Scott Wood <oss@buserror.net>
The qman portals are platform devices themselves, so they should
handle dma mappings. Creating a dummy platform device in order to
support dma mapping operations is not justified (and not portable).
Instead, do the mapping against the first portal that has been
initialised.

qman_query_fq*() may return other error codes apart from
-ERANGE, in which cases the error handling done by the
resource cleanup callers would be wrong. The patch
fixes the handling of those cases, and cleans up related
code inside the resource cleanup & release handlers (i.e.
replace hardcoded fqid value with corresponding define).
