The '__unreachable' and '__func_stack_frame_non_standard' sections are
only used at compile time. They're discarded for vmlinux but they
should also be discarded for modules.
Since this is a recurring pattern, prefix the section names with
".discard.". It's a nice convention and vmlinux.lds.h already discards
such sections.
Also remove the 'a' (allocatable) flag from the __unreachable section
since it doesn't make sense for a discarded section.

We should try to reinject previous events if any before trying to inject
new event if pending. If vmexit is triggered by L2 guest and L0 interested
in, we should reinject IDT-vectoring info to L2 through vmcs02 if any,
otherwise, we can consider new IRQs/NMIs which can be injected and call
nested events callback to switch from L2 to L1 if needed and inject the
proper vmexit events. However, 'commit 0ad3bed6c5 ("kvm: nVMX: move
nested events check to kvm_vcpu_running")' results in the handle events
order reversely on non-APICv box. This patch fixes it by bailing out for
pending events and not consider new events in this scenario.

pmc_reprogram_counter() always sets a sample period based on the value of
pmc->counter. However, hsw_hw_config() rejects sample periods less than
2^31 - 1. So for example, if a KVM guest does
struct perf_event_attr attr;
memset(&attr, 0, sizeof(attr));
attr.type = PERF_TYPE_RAW;
attr.size = sizeof(attr);
attr.config = 0x2005101c4; // conditional branches retired IN_TXCP
attr.sample_period = 0;
int fd = syscall(__NR_perf_event_open, &attr, 0, -1, -1, 0);
ioctl(fd, PERF_EVENT_IOC_DISABLE, 0);
ioctl(fd, PERF_EVENT_IOC_ENABLE, 0);
the guest kernel counts some conditional branch events, then updates the
virtual PMU register with a nonzero count. The host reaches
pmc_reprogram_counter() with nonzero pmc->counter, triggers EOPNOTSUPP
in hsw_hw_config(), prints "kvm_pmu: event creation failed" in
pmc_reprogram_counter(), and silently (from the guest's point of view) stops
counting events.
We fix event counting by forcing attr.sample_period to always be zero for
in_tx_cp counters. Sampling doesn't work, but it already didn't work and
can't be fixed without major changes to the approach in hsw_hw_config().

Kirill reported a warning from UBSAN about undefined behavior when using
protection keys. He is running on hardware that actually has support for
it, which is not widely available.
The warning triggers because of very large shifts of integers when doing a
pkey_free() of a large, invalid value. This happens because we never check
that the pkey "fits" into the mm_pkey_allocation_map().
I do not believe there is any danger here of anything bad happening
other than some aliasing issues where somebody could do:
pkey_free(35);
and the kernel would effectively execute:
pkey_free(8);
While this might be confusing to an app that was doing something stupid, it
has to do something stupid and the effects are limited to the app shooting
itself in the foot.

The revert of 991de2e590 ("PCI, x86: Implement pcibios_alloc_irq()
and pcibios_free_irq()") causes a problem for IOAPIC hotplug. The
problem is that IRQs are allocated and freed in pci_enable_device()
and pci_disable_device(). But there are some drivers which don't call
pci_disable_device(), and they have good reasons not calling it, so
if they're using IOAPIC their IRQs won't have a chance to be released
from the IOAPIC. When this happens IOAPIC hot-removal fails with a
kernel stack dump and an error message like this:
[149335.697989] pin16 on IOAPIC2 is still in use.
It turns out that we can fix it in a different way without moving IRQ
allocation into pcibios_alloc_irq(), thus avoiding the regression of
991de2e590. We can keep the allocation and freeing of IRQs as is
within pci_enable_device()/pci_disable_device(), without breaking any
previous assumption of the rest of the system, keeping compatibility
with both the legacy and the modern drivers. We can accomplish this by
implementing the existing __weak hook of pcibios_release_device() thus
when a pci device is about to be deleted we get notified in the hook
and take the chance to release its IRQ, if any, from the IOAPIC.
Implement pcibios_release_device() for x86 to release any IRQ not released
by the driver.

Fix to the exception table entry check by using probed address
instead of the address of copied instruction.
This bug may cause unexpected kernel panic if user probe an address

Unless user puts a kprobe on such address, this doesn't

Often all is needed is these small helpers, instead of compiler.h or a
full kprobes.h. This is important for asm helpers, in fact even some
asm/kprobes.h make use of these helpers... instead just keep a generic
asm file with helpers useful for asm code with the least amount of
clutter as possible.
Likewise we need now to also address what to do about this file for both
when architectures have CONFIG_HAVE_KPROBES, and when they do not. Then
for when architectures have CONFIG_HAVE_KPROBES but have disabled
CONFIG_KPROBES.
Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,
this means most architecture code cannot include asm/kprobes.h safely.
Correct this and add guards for architectures missing them.
Additionally provide architectures that not have kprobes support with
the default asm-generic solution. This lets us force asm/kprobes.h on
the header include/linux/kprobes.h always, but most importantly we can
now safely include just asm/kprobes.h on architecture code without
bringing the full kitchen sink of header files.
Two architectures already provided a guard against CONFIG_KPROBES on its
kprobes.h: sh, arch. The rest of the architectures needed gaurds added.
We avoid including any not-needed headers on asm/kprobes.h unless
kprobes have been enabled.
In a subsequent atomic change we can try now to remove compiler.h from
include/linux/kprobes.h.
During this sweep I've also identified a few architectures defining a
common macro needed for both kprobes and ftrace, that of the definition
of the breakput instruction up. Some refer to this as
BREAKPOINT_INSTRUCTION. This must be kept outside of the #ifdef
CONFIG_KPROBES guard.

One some systems the P-Unit accesses the PMIC to change various voltages
through the same bus as other kernel drivers use for e.g. battery
monitoring.
If a driver sends requests to the P-Unit which require the P-Unit to access
the PMIC bus while another driver is also accessing the PMIC bus various
bad things happen.
This commit adds a mutex to protect the P-Unit against simultaneous
accesses and 2 functions to lock / unlock this mutex.
Note on these systems the i2c-bus driver will request a sempahore from the
P-Unit for exclusive access to the PMIC bus when i2c drivers are accessing
it, but this does not appear to be sufficient, we still need to avoid
making certain P-Unit requests during the access window to avoid problems.

"Big picture:
- New intel_turbo_max_3 driver, providing max core frequency
information to the scheduler. Intel PMC APL support, s0ix read API,
and fixes.
- New Silead touchscreen platform touchscreen descriptions.
Additional hotkey support for the intel-hid driver.
- New model support for dell-laptop and hp_accel.
- Several cleanups, especially to the fujitsu-laptop and
intel_mid_powerbtn drivers.
Detail summary:

- Add Latitude 7480 and others to the DMI whitelist
intel-hid:
- Support 5 button array
thinkpad_acpi:
- Call led_classdev_notify_brightness_hw_changed on kbd brightness change
- Use brightness_set_blocking callback for LEDs
- Stop setting led_classdev brightness directly
acer-wmi:
- add another KEY_WLAN keycode
- Inform firmware that RF Button Driver is active
- setup accelerometer when machine has appropriate notify event
asus-wireless:
- Fix indentation

intel_pmc_core:
- fix out-of-bounds accesses on stack
intel_mid_powerbtn:
- Use SCU IPC directly
- Unify IRQ acknowledgment
- Move comment to where it belongs
- Unify PBSTATUS access
- Remove snail address
- Sort headers alphabetically
- Join string literals
- Enable driver for Merrifield
- Acknowledge interrupts
- Factor out mfld_ack()
- Introduce driver data
- Substitute mfld by mid
- Convert to use devm_*()
fujitsu-laptop:
- make hotkey handling functions more similar
- break up complex loop condition
- move keycode processing to separate functions
- decrease indentation in acpi_fujitsu_hotkey_notify()
- simplify logolamp_get()
- rework logolamp_set() to properly handle errors
- set default trigger for radio LED to rfkill-any
dell-smbios:
- Auto-select as needed
intel_mid_thermal:
- Fix module autoload
- Remove duplicated platform device ID
mlx-platform:
- mlxcpld-hotplug driver style fixes
hp_accel:
- Add support for HP ZBook 17"
