This table is too big for LaTeX output, and lacks columns
specs for LaTeX format.

Also, it has a hidden column, as there are some cell spans
with the wrong values.

Fix it, so it can be displayed properly on LaTeX/PDF.

This table has several troubles:
	- a duplicated "struct" on its name;
	- a reference to a V4L version 1 struct that will never
	  point to something (as we got rid of V4L1 API a long
	  time ago);
	- misses hints for LaTeX output (column size and longtable
	  style).

Fix them.

It should be noticed that the first column of this table is
not aligned with the rest. I suspect that this is a bug at
the flat-table extension.

Fix mosto fo the tables there in order to make them fit at the
page size.

There are, however, two exceptions: RGB and YUV big tables,
where adding the raw latex adjustbox caused the tables to not
be properly formatted. I suspect that the problem is because
those are long tables, but not really sure.

The thing is that Sphinx lacks an "adjustbox" tag that would
avoid the raw latex hacks.

There's a bug with LaTeX output on flat-tables with Sphinx 1.4.5
that prevents references at a cell span to be broken. As the
text is indeed too long, it makes sense to place the reference
to the pictures showing the VBI limits as a footnote.

That makes the text easier to read and also solves the issue
with LaTeX output.

Adjust the tables to fit at the LaTeX and PDF outputs.

I wrote a previous patch RFC to show the big table in landscape,
but it makes harder to read on displays.

So, instead, let's use the adjustbox to shrink the size of those
long tables, as the table size can still be visible on screen,
and it is a way better to read in horizontal position and
visible if printed.

LaTeX doesn't handle too well auto-width on tables, and ReST
markup requires an special tag to give it the needed hints.

As we're using A4 paper, we have 17cm of useful spaces. As
most media tables have widths, let's use it to generate the
needed via the following perl script:

my ($line_size, $table_header, $has_cols) = (17.5, 0, 0);
my $out;
my $header = "";
my @widths = ();
sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) }
while (<>) {
	if (!$table_header) {
		$has_cols = 1 if (m/..\s+tabularcolumns::/);
		if (m/..\s+flat-table::/) {
			$table_header = 1;
			$header = $_;
			next;
		}
		$out .= $_;
		next;
	}
	$header .= $_;
	@widths = split(/ /, $1) if (m/:widths:\s+(.*)/);
	if (m/^\n$/) {
		if (!$has_cols && @widths) {
			my ($tot, $t, $i) = (0, 0, 0);
			foreach my $v(@widths) { $tot += $v; };
			$out .= ".. tabularcolumns:: |";
			for ($i = 0; $i < scalar @widths - 1; $i++) {
				my $v = $widths[$i];
				my $w = round(10 * ($v * $line_size) / $tot) / 10;
				$out .= sprintf "p{%.1fcm}|", $w;
				$t += $w;
			}
			my $w = $line_size - $t;
			$out .= sprintf "p{%.1fcm}|\n\n", $w;
		}
		$out .= $header;
		$table_header = 0;
		$has_cols = 0;
		$header = "";
		@widths = ();

Both tables on this rst file were not shown right, as they miss
the proper tag (tabularcolumns) to specify the column widths
required for PDF and LaTeX output.

Also, the second table is too big to fit into one page. So,
it should use the longtable class to allow it to be split into
two pages.

Since commit 63a4cc24, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

No intended functional changes in this commit.

Cleaner than manipulating bio->bi_rw flags directly.
Signed-off-by: Jens Axboe <axboe@fb.com>

Commit abf54548 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.

Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

 "This update is to allow architecture emulation containers to function

  To use the new feature you have to add an F option to your binfmt_misc
  configuration"

From the docs:
 "The usual behaviour of binfmt_misc is to spawn the binary lazily when
  the misc format file is invoked.  However, this doesn't work very well
  in the face of mount namespaces and changeroots, so the F mode opens
  the binary as soon as the emulation is installed and uses the opened
  image to spawn the emulator, meaning it is always available once
  installed, regardless of how the environment changes"
