Allowing a guest to execute MWAIT without interception enables a guest
to put a (physical) CPU into a power saving state, where it takes
longer to return from than what may be desired by the host.
Don't give a guest that power over a host by default. (Especially,
since nothing prevents a guest from using MWAIT even when it is not
advertised via CPUID.)

Pull powerpc updates from Michael Ellerman:
"Notable changes:
- Support for 4PB user address space on 64-bit, opt-in via mmap().
- Removal of POWER4 support, which was accidentally broken in 2016
and no one noticed, and blocked use of some modern instructions.
- Workarounds so that the hypervisor can enable Transactional Memory
on Power9.
- A series to disable the DAWR (Data Address Watchpoint Register) on
Power9.
- More information displayed in the meltdown/spectre_v1/v2 sysfs
files.
- A vpermxor (Power8 Altivec) implementation for the raid6 Q
Syndrome.
- A big series to make the allocation of our pacas (per cpu area),
kernel page tables, and per-cpu stacks NUMA aware when using the
Radix MMU on Power9.
And as usual many fixes, reworks and cleanups.

The recent commit 15a3204d24a3 ("powerpc/64s: Set assembler machine
type to POWER4") set the machine type in our ASFLAGS when building the
kernel, and removed some ".machine power4" directives from various asm
files.
This broke the selftests build on old toolchains (that don't assume
Power4), because we build the kernel source files into the selftests
using different ASFLAGS.
The fix is simply to add -mpower4 to the selftest ASFLAGS as well.

Merge our fixes branch from the 4.16 cycle.
There were a number of important fixes merged, in particular some Power9
workarounds that we want in next for testing purposes. There's also been
some conflicting changes in the CPU features code which are best merged
and tested before going upstream.

Some processor revisions do not support transactional memory, and
additionally kernel support can be disabled. In either case the
tm-unavailable test should be skipped, otherwise it will fail with
a SIGILL.
That commit also sets this selftest to be called through the test
harness as it's done for other TM selftests.
Finally, it avoids using "ping" as a thread name since it's
ambiguous and can be confusing when shown, for instance,
in a kernel backtrace log.

"This Kselftest update for 4.17-rc1 consists of:
- Test build error fixes
- Fixes to prevent intel_pstate from building on non-x86 systems.
- New test for ion with vgem driver.
- Change to print the test name to /dev/kmsg to add context to kernel
failures if any uncovered from running the test.
- Kselftest framework enhancements to add KSFT_TAP_LEVEL environment
variable to prevent nested TAP headers being printed in the
Kselftest output.
Nested TAP13 headers could cause problems for some parsers. This
change suppresses the nested headers from test programs and test
shell scripts with changes to framework and Makefiles without

Ensure that ARCH is defined and that this only builds for
x86 architectures.
It is possible to build from the root of the Linux tree, which
will define ARCH, or to run make from the selftests/ directory
itself, which has no provision for defining ARCH, so this
change is to use the current definition (if any), or to check
uname -m if undefined.

Some tests cause the kernel to print things to the kernel log
buffer (ie. printk), in particular oops and warnings etc. However when
running all the tests in succession it's not always obvious which
test(s) caused the kernel to print something.
We can narrow it down by printing which test directory we're running
in to /dev/kmsg, if it's writable.

lib.mk run_tests and test program should print TAP header and set
KSFT_TAP_LEVEL to avoid a second TAP header to be printed.

Fixes a segfault occurring when e.g. <TAB> is pressed multiple times in the
ncurses tmon application. The segfault is caused by incrementing
cur_thermal_record in the main function without checking if it's value reached
NR_THERMAL_RECORD immediately. Since the boundary check only occurred in
update_thermal_data a race condition existed, which lead to an attempted read
beyond the last element of the trec array.
The fix was implemented by moving the cur_thermal_record incrementation to the
update_thermal_data function using a temporary variable on which the boundary
condition is checked before updating cur_thread_record, so that the variable is
never incremented beyond the trec array's boundary.
It seems the segfault does not occur on every machine: On a HP EliteBook G4 the
segfault happens, while it does not happen on a Thinkpad T540p.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.17 kernel cycle:
New drivers:
- Nintendo Wii GameCube GPIO, known as "Hollywood"
- Raspberry Pi mailbox service GPIO expander
- Spreadtrum main SC9860 SoC and IEC GPIO controllers.
Improvements:
- Implemented .get_multiple() callback for most of the
high-performance industrial GPIO cards for the ISA bus.
- ISA GPIO drivers now select the ISA_BUS_API instead of depending on
it. This is merged with the same pattern for all the ISA drivers
and some other Kconfig cleanups related to this.
Cleanup:
- Delete the TZ1090 GPIO drivers following the deletion of this SoC
from the ARM tree.
- Move the documentation over to driver-api to conform with the rest
of the kernel documentation build.
- Continue to make the GPIO drivers include only
<linux/gpio/driver.h> and not the too broad <linux/gpio.h> that we
want to get rid of.
- Managed to remove VLA allocation from two drivers pending more
fixes in this area for the next merge window.
- Misc janitorial fixes"

PRIu64 is defined in user space to match libc's uint64_t definition.
However, gpioevent_data structure in the kernel is defined using the
kernel's own __u64 type.
gpio-event-mon.c: In function ‘monitor_device’:
gpio-event-mon.c:102:19: warning: format ‘%lu’ expects argument of type
‘long unsigned int’, but argument 3 has type ‘__u64 {aka long long
unsigned int}’ [-Wformat=]
fprintf(stdout, "GPIO EVENT %" PRIu64 ": ", event.timestamp);
^~~~~~~~~~~~~~
LD /tmp/kselftest/gpiogpio-event-mon-in.o
LINK /tmp/kselftest/gpiogpio-event-mon
Fix is to replace PRIu64 with llu, which we know is what the kernel uses
for __u64.

On Hyper-V the VF NIC has the same MAC as the related synthetic NIC.
VF NIC can work under the synthetic NIC transparently, without its
own IP address. The existing KVP daemon only gets IP from the first
NIC matching a MAC address, and may not be able to find the IP in
this case.
This patch fixes the problem by searching the NIC matching the MAC,
and having an IP address. So, the IP address will be found and
reported to the host successfully.

Users of the custom firmware fallback interface is are not supposed to
use the firmware cache interface, this can happen if for instance the
one of the APIs which use the firmware cache is used first with one
firmware file and then the request_firmware_nowait(uevent=false) API
is used with the same file.
We'll soon become strict about this on the firmware interface to reject
such calls later, so correct the test scripts to avoid such uses as well.
We address this on the tests scripts by simply using unique names when
testing the custom fallback interface.

Since we now have knobs to twiddle what used to be set on kernel
configurations we can build one base kernel configuration and modify
behaviour to mimic such kernel configurations to test them.
Provided you build a kernel with:
CONFIG_TEST_FIRMWARE=y
CONFIG_FW_LOADER=y
CONFIG_FW_LOADER_USER_HELPER=y
CONFIG_IKCONFIG=y
CONFIG_IKCONFIG_PROC=y
We should now be able test all possible kernel configurations
when FW_LOADER=y. Note that when FW_LOADER=m we just don't provide
the built-in functionality of the built-in firmware.
If you're on an old kernel and either don't have /proc/config.gz
(CONFIG_IKCONFIG_PROC) or haven't enabled CONFIG_FW_LOADER_USER_HELPER
we cannot run these dynamic tests, so just run both scripts just
as we used to before making blunt assumptions about your setup
and requirements exactly as we did before.

When a kernel is not built with:
CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y
We don't currently enable testing fw_fallback.sh. For kernels that
still enable the fallback mechanism, its possible to use the async
request firmware API call request_firmware_nowait() using the custom
interface to use the fallback mechanism, so we should be able to test
this but we currently cannot.
We can enable testing without CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y
by relying on /proc/config.gz (CONFIG_IKCONFIG_PROC), if present. If you
don't have this we'll have no option but to rely on old heuristics for now.
We stuff the new kconfig_has() helper into our shared library as we'll
later expando on its use elsewhere.

Pull USB/PHY updates from Greg KH:
"Here is the big set of USB and PHY driver patches for 4.17-rc1.
Lots of USB typeC work happened this round, with code moving from the
staging directory into the "real" part of the kernel, as well as new
infrastructure being added to be able to handle the different types of
"roles" that typeC requires.
There is also the normal huge set of USB gadget controller and driver
updates, along with XHCI changes, and a raft of other tiny fixes all
over the USB tree. And the PHY driver updates are merged in here as
well as they interacted with the USB drivers in some places.
All of these have been in linux-next for a while with no reported
issues"

usbipd includes exported devices in response to exportable device list.
Exclude exported devices from exportable device list to avoid:
- import requests for devices that are exported only to fail the request.
- revealing devices that are imported by a client to another client.

Changed usbip_network, usbip_attach, usbip_list, and usbipd to use
and propagate the new error codes in server reply messages.
usbip_net_recv_op_common() is changed to take a pointer to status
return the status returned in the op_common.status to callers.
usbip_attach and usbip_list use the common interface to print error
messages to indicate why the request failed.
With this change the messages say why a request failed:
- when a client requests a device that is already exported:
usbip attach -r server_name -b 3-10.2
usbip: error: Attach Request for 3-10.2 failed - Device busy (exported)
- when a client requests a device that isn't exportable,
usbip attach -r server_name -b 3-10.4
usbip: error: Attach Request for 3-10.4 failed - Device not found
