Commit 4fd06960f120 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.
There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it
spreads any further.

Pull driver core updates from Greg KH:
"Here's the new driver core patches for 4.10-rc1.
Big thing here is the nice addition of "functional dependencies" to
the driver core. The idea has been talked about for a very long time,
great job to Rafael for stepping up and implementing it. It's been
tested for longer than the 4.9-rc1 date, we held off on merging it
earlier in order to feel more comfortable about it.
Other than that, it's just a handful of small other patches, some good
cleanups to the mess that is the firmware class code, and we have a
test driver for the deferred probe logic.
All of these have been in linux-next for a while with no reported
issues"

Pull smp hotplug updates from Thomas Gleixner:
"This is the final round of converting the notifier mess to the state
machine. The removal of the notifiers and the related infrastructure
will happen around rc1, as there are conversions outstanding in other
trees.
The whole exercise removed about 2000 lines of code in total and in
course of the conversion several dozen bugs got fixed. The new
mechanism allows to test almost every hotplug step standalone, so
usage sites can exercise all transitions extensively.
There is more room for improvement, like integrating all the
pointlessly different architecture mechanisms of synchronizing,
setting cpus online etc into the core code"

vfree() is going to use sleeping lock. free_ldt_struct() may be called
with disabled preemption, therefore we must use vfree_atomic() here.
E.g. call trace:

destroy_context_ldt()
__mmdrop()
finish_task_switch()
schedule_tail()
ret_from_fork()

In commit c5320926e370 ("mem-hotplug: introduce movable_node boot
option"), the memblock allocation direction is changed to bottom-up and
then back to top-down like this:
1. memblock_set_bottom_up(true), called by cmdline_parse_movable_node().
2. memblock_set_bottom_up(false), called by x86's numa_init().
Even though (1) occurs in generic mm code, it is wrapped by #ifdef
CONFIG_MOVABLE_NODE, which depends on X86_64.
This means that when we extend CONFIG_MOVABLE_NODE to non-x86 arches,
things will be unbalanced. (1) will happen for them, but (2) will not.
This toggle was added in the first place because x86 has a delay between
adding memblocks and marking them as hotpluggable. Since other arches
do this marking either immediately or not at all, they do not require
the bottom-up toggle.
So, resolve things by moving (1) from cmdline_parse_movable_node() to
x86's setup_arch(), immediately after the movable_node parameter has
been parsed.

Pull x86 microcode update from Ingo Molnar:
"The biggest change (by Borislav Petkov) is a thorough rewrite of the
Intel microcode loader and its interactions with the core code.
The biggest conceptual change is the decoupling of the microcode
loading on boot and application processors (which load the microcode
in different scenarios), so that both parse the input patches with as
few assumptions as possible - this also fixes various kernel address
space randomization bugs. (The AP side then goes on and caches the
result to improve boot performance.)
Since the AMD side already did this, this change also opened up the
path towards more unification/simplification of the core microcode
loading infrastructure:

Pull perf updates from Ingo Molnar:
"This update is pretty big and almost exclusively includes tooling
changes, because v4.9's LTS status forced to completion most of the
pending kernel side hardware enablement work and because we tried to
freeze core perf work a bit to give a time window for the fuzzing
efforts.
The diff is large mostly due to the JSON hardware event tables added
for Intel and Power8 CPUs. This was a popular feature request from
people working close to hardware and from the HPC community.
Tree size is big because this added the CPU event tables for over a
decade of Intel CPUs. Future changes for a CPU vendor alrady support
should be much smaller, as events for new models are added. The new
events are listed in 'perf list', for the CPU model the tool is
running on. If you find an interesting event it can be used as-is:
$ perf stat -a -e l2_lines_out.pf_clean sleep 1
Performance counter stats for 'system wide':
7,860,403 l2_lines_out.pf_clean
1.000624918 seconds time elapsed
The event lists can be searched the usual 'perf list' fashion for
(case insensitive) substrings as well:
$ perf list l2_lines_out
List of pre-defined events (to be used in -e):
cache:
l2_lines_out.demand_clean
[Clean L2 cache lines evicted by demand]
l2_lines_out.demand_dirty
[Dirty L2 cache lines evicted by demand]
l2_lines_out.dirty_all
[Dirty L2 cache lines filling the L2]
l2_lines_out.pf_clean
[Clean L2 cache lines evicted by L2 prefetch]
l2_lines_out.pf_dirty
[Dirty L2 cache lines evicted by L2 prefetch]
etc.
There's a few high level categories as well that can be listed:
'cache', 'floating point', 'frontend', 'memory', 'pipeline', 'virtual
memory'.
Existing generic events and workflows should work as-is.
The only kernel side change is a late breaking fix for an older
regression, related to Intel BTS, LBR and PT feature interaction.
