Pull more powerpc updates from Michael Ellerman:
"Highlights include:
- an update of the disassembly code used by xmon to the latest
versions in binutils. We've received permission from all the
authors of the relevant binutils changes to relicense their changes
to the relevant files from GPLv3 to GPLv2, for inclusion in Linux.
Thanks to Peter Bergner for doing the leg work to get permission
from everyone.
- addition of the "architected" Power9 CPU table entry, allowing us
to boot in Power9 architected mode under a hypervisor.
- updates to the Power9 PMU code.
- implementation of clear_bit_unlock_is_negative_byte() to optimise
unlock_page().
- Freescale updates from Scott: "Highlights include 8xx breakpoints
and perf, t1042rdb display support, and board updates."

Fix typos and add the following to the scripts/spelling.txt:
an user||a user
an userspace||a userspace
I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the
list. I felt it is endless to find words that start with "user" such as
"userland" etc., so must draw a line somewhere.

After updating ppc-dis.c, ppc-opc.c and ppc.h the following changes were
made to enable compilation and working of xmon:
1. Remove all disassembler_info
2. Use xmon's printf/print_address to output data and addresses
respectively.
3. All bfd_* types and casts have been removed.
4. Optimizations related to opcd_indices have been removed.
5. The dialect is set based on cpu features.
6. PPC_OPCODE_CLASSIC is no longer supported in the new
disassembler.
7. VLE opcode parsing and printing has been stripped.
8. Coding style conventions used for those routines has
been retained and it does not match our CodingStyle.
9. The highest supported dialect is POWER9.
10. Defined ATTRIBUTE_UNUSED in ppc-dis.c.
11. Defined _(x) in ppc-dis.c.
Finally, we remove the dependency on BROKEN so that XMON_DISASSEMBLY can
be enabled again.

Upgrade ppc-opc.c, ppc-dis.c and ppc.h to the versions belonging to the
following binutils commit:
65b650b4c7463f4508bed523c24ab0031a5ae5cd
* ppc-dis.c (print_insn_powerpc): Don't skip all operands after
setting skip_optional.
That is the last version of those files that were licensed under GPLv2.
This leaves the code in a state that does not compile, because the
binutils code needs to be tweaked to work in the kernel. We don't fix
that in this commit, because we want to import more binutils changes in
subsequent commits. So for now we mark XMON_DISASSEMBLY as BROKEN, so it
can't be built.

This includes:
* version 1.24 of ppc-dis.c
* version 1.88 of ppc-opc.c
* version 1.23 of ppc.h
I can't vouch for the accuracy etc. of these changes, but it brings
us into line with binutils - and from a cursory test appears to work
fine.

The merged version follows the ppc64 version pretty closely mostly,
and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version.
The main difference for ppc64 is that the 'p' command to call
show_state (which was always pretty dodgy) has been replaced by
the ppc32 'p' command, which calls a given procedure (so in fact
the old 'p' command behaviour can be achieved with 'p $show_state').
