While we don't have any documentation for it, based on what's
there at Kaffeine and VDR, it seems that this command should
be issued before start using CA. So, document it as such.

For most of the stuff there, documenting is easy, as the
header file contains information.
Yet, I was unable to document two data structs:
ca_msg and ca_descr
As those two structs are used by a few drivers, keep them.

This ioctl seems to be some attempt to support a feature
at the bt8xx dst_ca driver. Yet, as said there, it
"needs more work". Right now, the code there is just
a boilerplate.
At the end of the day, no driver uses this ioctl, nor it is
documented anywhere (except for "needs more work").
So, get rid of it.

Now that frontend.h contains most documentation for the frontend,
remove the duplicated information from Documentation/ and use the

Most of the stuff at the Digital TV frontend header file
are documented only at the Documentation. However, a few
kernel-doc markups are there, several of them with parsing
issues.
Add the missing documentation, copying definitions from the
Documentation when it applies, fixing some bugs.
Please notice that DVBv3 stuff that were deprecated weren't
commented by purpose. Instead, they were clearly tagged as
such.
This patch prepares to move part of the documentation from
Documentation/ to kernel-doc comments.

struct dtv_cmds_h is just an ancillary struct used by the

Both CA and decoders are optional. Also, the presence or
absence has nothing to do on being a PCI card or not.
Nowadays, most hardware leaves the decoders to either the
GPU or to some ISP inside the SoC, instead of implementing
it inside the Digital TV part of the device.
So, change the wording to reflect the hardware changes.

====================
Netfilter updates for next-net (part 2)
The following patchset contains Netfilter updates for net-next. This
patchset includes updates for nf_tables, removal of
CONFIG_NETFILTER_DEBUG and a new mode for xt_hashlimit. More
specifically, they:
1) Add new rate match mode for hashlimit, this introduces a new revision
for this match. The idea is to stop matching packets until ratelimit
criteria stands true. Patch from Vishwanath Pai.
2) Add ->select_ops indirection to nf_tables named objects, so we can
choose between different flavours of the same object type, patch from
Pablo M. Bermudo.
3) Shorter function names in nft_limit, basically:
s/nft_limit_pkt_bytes/nft_limit_bytes, also from Pablo M. Bermudo.
4) Add new stateful limit named object type, this allows us to create
limit policies that you can identify via name, also from Pablo.
5) Remove unused hooknum parameter in conntrack ->packet indirection.
From Florian Westphal.
6) Patches to remove CONFIG_NETFILTER_DEBUG and macros such as
IP_NF_ASSERT and IP_NF_ASSERT. From Varsha Rao.
7) Add nf_tables_updchain() helper function and use it from
nf_tables_newchain() to make it more maintainable. Similarly,
add nf_tables_addchain() and use it too.
8) Add new netlink NLM_F_NONREC flag, this flag should only be used for
deletion requests, specifically, to support non-recursive deletion.
Based on what we discussed during NFWS'17 in Faro.
9) Use NLM_F_NONREC from table and sets in nf_tables.
10) Support for recursive chain deletion. Table and set deletion
commands come with an implicit content flush on deletion, while
chains do not. This patch addresses this inconsistency by adding
the code to perform recursive chain deletions. This also comes with
the bits to deal with the new NLM_F_NONREC netlink flag.

Pull x86 cache quality monitoring update from Thomas Gleixner:
"This update provides a complete rewrite of the Cache Quality
Monitoring (CQM) facility.
The existing CQM support was duct taped into perf with a lot of issues
and the attempts to fix those turned out to be incomplete and
horrible.
After lengthy discussions it was decided to integrate the CQM support
into the Resource Director Technology (RDT) facility, which is the
obvious choise as in hardware CQM is part of RDT. This allowed to add
Memory Bandwidth Monitoring support on top.
As a result the mechanisms for allocating cache/memory bandwidth and
the corresponding monitoring mechanisms are integrated into a single
management facility with a consistent user interface"

Pull x86 mm changes from Ingo Molnar:
"PCID support, 5-level paging support, Secure Memory Encryption support
The main changes in this cycle are support for three new, complex
hardware features of x86 CPUs:
- Add 5-level paging support, which is a new hardware feature on
upcoming Intel CPUs allowing up to 128 PB of virtual address space
and 4 PB of physical RAM space - a 512-fold increase over the old
limits. (Supercomputers of the future forecasting hurricanes on an
ever warming planet can certainly make good use of more RAM.)
Many of the necessary changes went upstream in previous cycles,
v4.14 is the first kernel that can enable 5-level paging.
This feature is activated via CONFIG_X86_5LEVEL=y - disabled by
default.
(By Kirill A. Shutemov)
- Add 'encrypted memory' support, which is a new hardware feature on
upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system
RAM to be encrypted and decrypted (mostly) transparently by the
CPU, with a little help from the kernel to transition to/from
encrypted RAM. Such RAM should be more secure against various
attacks like RAM access via the memory bus and should make the
radio signature of memory bus traffic harder to intercept (and
decrypt) as well.
This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled
by default.
(By Tom Lendacky)
- Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a
hardware feature that attaches an address space tag to TLB entries
and thus allows to skip TLB flushing in many cases, even if we
switch mm's.
(By Andy Lutomirski)
All three of these features were in the works for a long time, and
it's coincidence of the three independent development paths that they
are all enabled in v4.14 at once"

The alpha/marvel code currently implements an irq_chip for handling
interrupts; due to how irq_chip handling is done, it's necessary for the
irq_chip methods to be invoked from hardirq context, even on a a
real-time kernel. Because the spinlock_t type becomes a "sleeping"
spinlock w/ RT kernels, it is not suitable to be used with irq_chips.
A quick audit of the operations under the lock reveal that they do only
minimal, bounded work, and are therefore safe to do under a raw spinlock.
