af05559854 Merge airlied/drm-next into drm-misc-next
I need this to be able to apply the deferred fbdev setup patches, I
need the relevant prep work that landed through the drm-intel tree.

Also squash in conflict fixup from Laurent Pinchart.

ee9f8fce99 x86/unwind: Add the ORC unwinder
Add the new ORC unwinder which is enabled by CONFIG_ORC_UNWINDER=y.
It plugs into the existing x86 unwinder framework.

It relies on objtool to generate the needed .orc_unwind and
.orc_unwind_ip sections.

For more details on why ORC is used instead of DWARF, see
Documentation/x86/orc-unwinder.txt - but the short version is
that it's a simplified, fundamentally more robust debugninfo
data structure, which also allows up to two orders of magnitude
faster lookups than the DWARF unwinder - which matters to
profiling workloads like perf.

Thanks to Andy Lutomirski for the performance improvement ideas:
splitting the ORC unwind table into two parallel arrays and creating a
fast lookup table to search a subset of the unwind table.

dd10be381c media: svg: avoid too long lines
Sending patches with SVG files via e-mail has a drawback: line
size could be bigger than 998, with is the limit given by
RFC 5322[1]. So, we need to enforce a lower limit, in order to
allow those patches to be properly reviewed.

[1] https://tools.ietf.org/html/rfc5322#section-2.1.1

So, use this small Perl script to limit columns size to ~900.

use Text::Wrap;
$Text::Wrap::columns = 900;

$t.=$_ while (<>);

print wrap("","",$t);

f99bcb2cdb documentation: Fix relation between nohz_full and rcu_nocbs
If a CPU is specified in the nohz_full= kernel boot parameter to a
kernel built with CONFIG_NO_HZ_FULL=y, then that CPU's callbacks will
be offloaded, just as if that CPU had also been specified in the
rcu_nocbs= kernel boot parameter.  But the current documentation
states that the user must keep these two boot parameters manually
synchronized.  This commit therefore updates the documentation to
reflect reality.

As the comments from Heiko Stuebner <heiko@sntech.de> that compatible
should not contain any placeholders, this patch fix it for rk3228 SoC.

Note that this is a fix for v4.13, due to fixing the current non-standard

  Mauro has gone through and fixed up a lot of top-level documentation

6ac1d1532c ata: sata_rcar: add gen[23] fallback compatibility strings
Add fallback compatibility string for R-Car Gen 2 and 3.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.
