Linus Torvalds c2aee376cf USB fixes for 4.18-rc3
Here is a number of USB gadget and other driver fixes for 4.18-rc3.
 
 There's a bunch of them here, most of them being gadget driver and xhci
 host controller fixes for reported issues (as normal), but there are
 also some new device ids, and some fixes for the typec code.
 
 There is an acpi core patch in here that was acked by the acpi
 maintainer as it is needed for the typec fixes in order to properly
 solve a problem in that driver.
 
 All of these have been in linux-next this week with no reported issues.

Linus Torvalds a11e1d432b Revert changes to convert to ->poll_mask() and aio IOCB_CMD_POLL
The poll() changes were not well thought out, and completely
unexplained.  They also caused a huge performance regression, because
"->poll()" was no longer a trivial file operation that just called down
to the underlying file operations, but instead did at least two indirect
calls.

Indirect calls are sadly slow now with the Spectre mitigation, but the
performance problem could at least be largely mitigated by changing the
"->get_poll_head()" operation to just have a per-file-descriptor pointer
to the poll head instead.  That gets rid of one of the new indirections.

But that doesn't fix the new complexity that is completely unwarranted
for the regular case.  The (undocumented) reason for the poll() changes
was some alleged AIO poll race fixing, but we don't make the common case
slower and more complex for some uncommon special case, so this all
really needs way more explanations and most likely a fundamental
redesign.

[ This revert is a revert of about 30 different commits, not reverted
  individually because that would just be unnecessarily messy  - Linus ]

Flavio Leitner 9c4c325252 skbuff: preserve sock reference when scrubbing the skb.
The sock reference is lost when scrubbing the packet and that breaks
TSQ (TCP Small Queues) and XPS (Transmit Packet Steering) causing
performance impacts of about 50% in a single TCP stream when crossing
network namespaces.

XPS breaks because the queue mapping stored in the socket is not
available, so another random queue might be selected when the stack
needs to transmit something like a TCP ACK, or TCP Retransmissions.
That causes packet re-ordering and/or performance issues.

TSQ breaks because it orphans the packet while it is still in the
host, so packets are queued contributing to the buffer bloat problem.

Preserving the sock reference fixes both issues. The socket is
orphaned anyways in the receiving path before any relevant action
and on TX side the netfilter checks if the reference is local before
use it.

Tobin C. Harding 805f16a5f1 Documentation: e1000: Fix docs build error
Recent patch updated e1000 docs to rst format.  Docs build (`make
htmldocs`) is currently failing due to this file with error:

        (SEVERE/4) Unexpected section title.

This is because a section of the file is indented 2 spaces.  Build error
can be cleared by aligning the text with column 0.  While we are changing
these lines we can make sure line length does not exceed 72, that
newlines following headings are uniform, and that full stops are
followed by two spaces.

Align text with column 0, limit line length to 72, ensure two spaces
follow all full stops, ensure uniform use of newlines after heading.

Linus Torvalds 6a4d4b3253 RISC-V Updates for the 4.18 Merge Window
This tag contains some small RISC-V updates I'd like to target for 4.18.
 They are all fairly small this time.  Here's a short summary, there's
 more info in the commits/merges.
 
 * A fix to __clear_user to respect the passed arguments.
 * Enough support for the perf subsystem to work with RISC-V's ISA
   defined performance counters.
 * Support for sparse and cleanups suggested by it.
 * Support for R_RISCV_32 (a relocation, not the 32-bit ISA).
 * Some MAINTAINERS cleanups.
 * The addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always
   present.
 
 I've given these a simple build+boot test.

Mauro Carvalho Chehab b701745097 docs: can.rst: fix a footnote reference
As stated at:
	http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#footnotes

A footnote should contain either a number, a reference or
an auto number, e. g.:
        [1], [#f1] or [#].

While using [*] accidentaly works for html, it fails for other
document outputs. In particular, it causes an error with LaTeX
output, causing all books after networking to not be built.

So, replace it by a valid syntax.
