Add compatible strings for r8a7744. No driver change is needed as
"renesas,rcar-gen2-vin" will activate the right code.However, it is good
practice to document compatible strings for the specific SoC as this
allows SoC specific changes to the driver if needed, in addition to
document SoC support and therefore allow checkpatch.pl to validate
compatible string values.

Alexei Starovoitov says:
====================
pull-request: bpf-next 2018-10-08
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow
BPF programs to perform lookups for sockets in a network namespace. This would
allow programs to determine early on in processing whether the stack is
expecting to receive the packet, and perform some action (eg drop,
forward somewhere) based on this information.
2) per-cpu cgroup local storage from Roman Gushchin.
Per-cpu cgroup local storage is very similar to simple cgroup storage
except all the data is per-cpu. The main goal of per-cpu variant is to
implement super fast counters (e.g. packet counters), which don't require
neither lookups, neither atomic operations in a fast path.
The example of these hybrid counters is in selftests/bpf/netcnt_prog.c
3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet
4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski
5) rename of libbpf interfaces from Andrey Ignatov.
libbpf is maturing as a library and should follow good practices in
library design and implementation to play well with other libraries.
This patch set brings consistent naming convention to global symbols.
6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov
to let Apache2 projects use libbpf
7) various AF_XDP fixes from Björn and Magnus

This adds a KVM_PPC_NO_HASH flag to the flags field of the
kvm_ppc_smmu_info struct, and arranges for it to be set when
running as a nested hypervisor, as an unambiguous indication
to userspace that HPT guests are not supported. Reporting the
KVM_CAP_PPC_MMU_HASH_V3 capability as false could be taken as
indicating only that the new HPT features in ISA V3.0 are not
supported, leaving it ambiguous whether pre-V3.0 HPT features
are supported.

With this, userspace can enable a KVM-HV guest to run nested guests
under it.
The administrator can control whether any nested guests can be run;
setting the "nested" module parameter to false prevents any guests
becoming nested hypervisors (that is, any attempt to enable the nested
capability on a guest will fail). Guests which are already nested
hypervisors will continue to be so.

This adds a one-reg register identifier which can be used to read and
set the virtual PTCR for the guest. This register identifies the
address and size of the virtual partition table for the guest, which
contains information about the nested guests under this guest.
Migrating this value is the only extra requirement for migrating a
guest which has nested guests (assuming of course that the destination
host supports nested virtualization in the kvm-hv module).

My eyesight is not in good shape, which means that I have difficulty
reading the online Linux documentation. Specifically, body text is
oddly small compared to list items and the contrast of various text
elements is too low for me to be able to see easily.
Therefore, alter the HTML theme overrides to make the text larger and
increase the contrast for better visibility, and trust the typeface
choices of the reader's browser.
For the PDF output, increase the text size, use a sans-serif typeface
for sans-serif text, and use a serif typeface for "roman" serif text.

After the cleanups from Baoquan He, make it even more readable:
- Remove the 'bits' area size column: it's pretty pointless and was even
wrong for some of the entries. Given that MB, GB, TB, PT are 10, 20,
30 and 40 bits, a "8 TB" size description makes it obvious that it's
43 bits.
- Introduce an "offset" column:
--------------------------------------------------------------------------------
start addr | offset | end addr | size | VM area description
-----------------|------------|------------------|---------|--------------------
...
ffff880000000000 | -120 TB | ffffc7ffffffffff | 64 TB | direct mapping of all physical memory (page_offset_base),
this is what limits max physical memory supported.
The -120 TB notation makes it obvious where this particular virtual memory
region starts: 120 TB down from the top of the 64-bit virtual memory space.
Especially the layout of the kernel mappings is a *lot* more obvious when
written this way, plus it's much easier to compare it with the size column
and understand/check/validate and modify the kernel's layout in the future.
- Mark the part from where the 47-bit and 56-bit kernel layouts are 100% identical,
this starts at the -512 GB offset and the EFI region.
- Re-shuffle the size desciptions to be continous blocks of sizes, instead of the
often mixed size. I.e. write "0.5 TB" instead of "512 GB" if we are still in
the TB-granular region of the map.
- Make the 47-bit and 56-bit descriptions use the *exact* same layout and wording,
and only differ where there's a material difference. This makes it easy to compare
the two tables side by side by switching between two terminal tabs.
- Plus enhance a lot of other stylistic/typographical details: make the tables
explicitly tabular, add headers, enhance certain entries, etc. etc.
Note that there are some apparent errors in the tables as well, but I'll fix
them in a separate patch to make it easier to review/validate.

In Documentation/x86/x86_64/mm.txt, the description of the x86-64 virtual
memory layout has become a confusing hodgepodge of inconsistencies:
- there's a hard to read mixture of 'TB' and 'bits' notation
- the entries sometimes mention a size in the description and sometimes not
- sometimes they list holes by address, sometimes only as an 'unused hole' line
So make it all a coherent, readable, well organized description.
