Now that we build with -Wimplicit-fallthrough=3, some warnings are
produced in the arch/mips perf events code that are promoted to errors:
arch/mips/kernel/perf_event_mipsxx.c:792:3: error: this statement may fall through [-Werror=implicit-fallthrough=]
arch/mips/kernel/perf_event_mipsxx.c:795:3: error: this statement may fall through [-Werror=implicit-fallthrough=]
arch/mips/kernel/perf_event_mipsxx.c:798:3: error: this statement may fall through [-Werror=implicit-fallthrough=]
arch/mips/kernel/perf_event_mipsxx.c:1407:6: error: this statement may fall through [-Werror=implicit-fallthrough=]
Assume the fall throughs are deliberate amd annotate/eliminate them.

In commit 8764c4ca5049 ("gpio: em: use the managed version of
gpiochip_add_data()") we implicitly altered the ordering of resource
freeing: since gpiochip_remove() calls gpiochip_irqchip_remove()
internally, we now can potentially use the irq_domain after it was
destroyed in the remove() callback (as devm resources are freed after
remove() has returned).
Use devm_add_action_or_reset() to keep the ordering right and entirely
kill the remove() callback in the driver.

clang gets confused by an uninitialized variable in what looks
to it like a never executed code path:
arch/x86/kernel/acpi/boot.c:618:13: error: variable 'polarity' is uninitialized when used here [-Werror,-Wuninitialized]
polarity = polarity ? ACPI_ACTIVE_LOW : ACPI_ACTIVE_HIGH;

int rc, irq, trigger, polarity;

arch/x86/kernel/acpi/boot.c:617:12: error: variable 'trigger' is uninitialized when used here [-Werror,-Wuninitialized]
trigger = trigger ? ACPI_LEVEL_SENSITIVE : ACPI_EDGE_SENSITIVE;
^~~~~~~
arch/x86/kernel/acpi/boot.c:606:22: note: initialize the variable 'trigger' to silence this warning
int rc, irq, trigger, polarity;
^
= 0
This is unfortunately a design decision in clang and won't be fixed.
Changing the acpi_get_override_irq() macro to an inline function
reliably avoids the issue.

Thomas and Juliana report a deadlock when running:
(rmmod nf_conntrack_netlink/xfrm_user)
conntrack -e NEW -E &
modprobe -v xfrm_user
They provided following analysis:
conntrack -e NEW -E
netlink_bind()
netlink_lock_table() -> increases "nl_table_users"
nfnetlink_bind()
# does not unlock the table as it's locked by netlink_bind()
__request_module()
call_usermodehelper_exec()
This triggers "modprobe nf_conntrack_netlink" from kernel, netlink_bind()
won't return until modprobe process is done.
"modprobe xfrm_user":
xfrm_user_init()
register_pernet_subsys()
-> grab pernet_ops_rwsem
..
netlink_table_grab()
calls schedule() as "nl_table_users" is non-zero
so modprobe is blocked because netlink_bind() increased
nl_table_users while also holding pernet_ops_rwsem.
"modprobe nf_conntrack_netlink" runs and inits nf_conntrack_netlink:
ctnetlink_init()
register_pernet_subsys()
-> blocks on "pernet_ops_rwsem" thanks to xfrm_user module
both modprobe processes wait on one another -- neither can make
progress.
Switch netlink_bind() to "nowait" modprobe -- this releases the netlink
table lock, which then allows both modprobe instances to complete.

The Performance Stop Status and Control Register (PSSCR) is used to
control the power saving facilities of the processor. This register
has various fields, some of which can be modified only in hypervisor
state, and others which can be modified in both hypervisor and
privileged non-hypervisor state. The bits which can be modified in
privileged non-hypervisor state are referred to as guest visible.
Currently the L0 hypervisor saves and restores both it's own host
value as well as the guest value of the PSSCR when context switching
between the hypervisor and guest. However a nested hypervisor running
it's own nested guests (as indicated by kvmhv_on_pseries()) doesn't
context switch the PSSCR register. That means if a nested (L2) guest
modifies the PSSCR then the L1 guest hypervisor will run with that
modified value, and if the L1 guest hypervisor modifies the PSSCR and
then goes to run the nested (L2) guest again then the L2 PSSCR value
will be lost.
Fix this by having the (L1) nested hypervisor save and restore both
its host and the guest PSSCR value when entering and exiting a
nested (L2) guest. Note that only the guest visible parts of the PSSCR
are context switched since this is all the L1 nested hypervisor can
access, this is fine however as these are the only fields the L0
hypervisor provides guest control of anyway and so all other fields
are ignored.
This could also have been implemented by adding the PSSCR register to
the hv_regs passed to the L0 hypervisor as input to the H_ENTER_NESTED
hcall, however this would have meant updating the structure layout and
thus required modifications to both the L0 and L1 kernels. Whereas the
approach used doesn't require L0 kernel modifications while achieving
the same result.

The ability to run nested guests under KVM means that a guest can also
act as a hypervisor for it's own nested guest. Currently
ppc_set_pmu_inuse() assumes that either FW_FEATURE_LPAR is set,
indicating a guest environment, and so sets the pmcregs_in_use flag in
the lppaca, or that it isn't set, indicating a hypervisor environment,
and so sets the pmcregs_in_use flag in the paca.
The pmcregs_in_use flag in the lppaca is used to communicate this
information to a hypervisor and so must be set in a guest environment.
The pmcregs_in_use flag in the paca is used by KVM code to determine
whether the host state of the performance monitoring unit (PMU) must
be saved and restored when running a guest.
Thus when a guest also acts as a hypervisor it must set this bit in
both places since it needs to ensure both that the real hypervisor
saves it's PMU registers when it runs (requires pmcregs_in_use flag in
lppaca), and that it saves it's own PMU registers when running a
nested guest (requires pmcregs_in_use flag in paca).
Modify ppc_set_pmu_inuse() so that the pmcregs_in_use bit is set in
both the lppaca and the paca when a guest (LPAR) is running with the
capability of running it's own guests (CONFIG_KVM_BOOK3S_HV_POSSIBLE).

The performance monitoring unit (PMU) registers are saved on guest
exit when the guest has set the pmcregs_in_use flag in its lppaca, if
it exists, or unconditionally if it doesn't. If a nested guest is
being run then the hypervisor doesn't, and in most cases can't, know
if the PMU registers are in use since it doesn't know the location of
the lppaca for the nested guest, although it may have one for its
immediate guest. This results in the values of these registers being
lost across nested guest entry and exit in the case where the nested
guest was making use of the performance monitoring facility while it's
nested guest hypervisor wasn't.
Further more the hypervisor could interrupt a guest hypervisor between
when it has loaded up the PMU registers and it calling H_ENTER_NESTED
or between returning from the nested guest to the guest hypervisor and
the guest hypervisor reading the PMU registers, in
kvmhv_p9_guest_entry(). This means that it isn't sufficient to just
save the PMU registers when entering or exiting a nested guest, but
that it is necessary to always save the PMU registers whenever a guest
is capable of running nested guests to ensure the register values
aren't lost in the context switch.
Ensure the PMU register values are preserved by always saving their
value into the vcpu struct when a guest is capable of running nested
guests.
This should have minimal performance impact however any impact can be
avoided by booting a guest with "-machine pseries,cap-nested-hv=false"
on the qemu commandline.

The virtual real mode addressing (VRMA) mechanism is used when a
partition is using HPT (Hash Page Table) translation and performs real
mode accesses (MSR[IR|DR] = 0) in non-hypervisor mode. In this mode
effective address bits 0:23 are treated as zero (i.e. the access is
aliased to 0) and the access is performed using an implicit 1TB SLB
entry.
The size of the RMA (Real Memory Area) is communicated to the guest as
the size of the first memory region in the device tree. And because of
the mechanism described above can be expected to not exceed 1TB. In
the event that the host erroneously represents the RMA as being larger
than 1TB, guest accesses in real mode to memory addresses above 1TB
will be aliased down to below 1TB. This means that a memory access
performed in real mode may differ to one performed in virtual mode for
the same memory address, which would likely have unintended
consequences.
To avoid this outcome have the guest explicitly limit the size of the
RMA to the current maximum, which is 1TB. This means that even if the
first memory block is larger than 1TB, only the first 1TB should be
accessed in real mode.

Pull stream_open() updates from Kirill Smelkov:
"This time on stream_open front it is only two small changes:
- the first one converts stream_open.cocci to treat all functions
that start with wait_.* as blocking. Previously it was only
wait_event_.* functions that were considered as blocking, but this
was falsely reporting several deadlock cases as only warning.
This was picked by linux-kbuild and entered mainline as commit
0c4ab18fc33b ("coccinelle: api/stream_open: treat all wait_.*()
calls as blocking"), and already merged earlier.
- the second one teaches stream_open.cocci to consider files as being
stream-like even if they use noop_llseek. It results in two more
drivers being converted to stream_open() (mousedev.c and
hid-sensor-custom.c)"

Pull x86 platform driver updates from Andy Shevchenko:
"Gathered a bunch of x86 platform driver changes. It's rather big,
since includes two big refactors and completely new driver:
- ASUS WMI driver got a big refactoring in order to support the TUF
Gaming laptops. Besides that, the regression with backlight being
permanently off on various EeePC laptops has been fixed.
- Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
- Intel PMC core driver has been extended to be ACPI enumerated if
the DSDT provides device with _HID "INT33A1". This allows to
convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
- From now on the Intel Speed Select Technology is supported thru a
corresponding driver. This driver provides an access to the
features of the ISST, such as Performance Profile, Core Power, Base
frequency and Turbo Frequency.
- Mellanox platform drivers has been refactored and now extended to
support more systems, including new coming ones.
- The OLPC XO-1.75 platform is now supported.
- CB4063 Beckhoff Automation board is using PMC clocks, provided via
pmc_atom driver, for ethernet controllers in a way that they can't
be managed by the clock driver. The quirk has been extended to
cover this case.
- Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more
models based on the same platform.
- Xiaomi notebooks have WMI interface enabled. Thus, the driver to
support it has been provided. It required some extension of the
generic WMI library, which allows to propagate opaque context to
the ->probe() of the individual drivers.
This release includes debugfs clean up from Greg KH for several
drivers that drop return code check and make debugfs absence or
failure non-fatal.
Also miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers"

This lets us catch new architectures that implicitly make use of clone3
without setting __ARCH_WANT_SYS_CLONE3.
Failing on missing __ARCH_WANT_SYS_CLONE3 is a good indicator that they
either did not really want this syscall or haven't really thought about
whether it needs special treatment and just accidently included it in
their entrypoints by e.g. generating their syscall table automatically
via asm-generic/unistd.h
This patch has been compile-tested for the h8300 architecture which is
one of the architectures that does not yet implement clone3 and
generates its syscall table via asm-generic/unistd.h.

A while ago Arnd made it possible to give new system calls the same
syscall number on all architectures (except alpha). To not break this
nice new feature let's mark 435 for clone3 as reserved on all
architectures that do not yet implement it.
Even if an architecture does not plan to implement it this ensures that
new system calls coming after clone3 will have the same number on all
architectures.

This patch continues 10dce8af3422 (fs: stream_open - opener for
stream-like files so that read and write can run simultaneously without
deadlock) and c5bf68fe0c86 (*: convert stream-like files from
nonseekable_open -> stream_open) and teaches steam_open.cocci to
consider files as being stream-like not only if they have
.llseek=no_llseek, but also if they have .llseek=noop_llseek.
This is safe to do: the comment about noop_llseek says
This is an implementation of ->llseek useable for the rare special case when
userspace expects the seek to succeed but the (device) file is actually not
able to perform the seek. In this case you use noop_llseek() instead of
falling back to the default implementation of ->llseek.
and in general noop_llseek was massively added to drivers in 6038f373a3dc
(llseek: automatically add .llseek fop) when changing default for NULL .llseek
from NOP to no_llseek with the idea to avoid breaking compatibility, if
maybe some user-space program was using lseek on a device without caring
about the result, but caring if it was an error or not.
Amended semantic patch produces two changes when applied tree-wide:
drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open.
drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

"Notable changes:
- Removal of the NPU DMA code, used by the out-of-tree Nvidia driver,
as well as some other functions only used by drivers that haven't

- A fix for a bug in our handling of hardware watchpoints (eg. perf
record -e mem: ...) which could lead to register corruption and
kernel crashes.
- Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for
vmalloc when using the Radix MMU.
- A large but incremental rewrite of our exception handling code to
use gas macros rather than multiple levels of nested CPP macros.
And the usual small fixes, cleanups and improvements.
