git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 fixes from Heiko Carstens:
- Add various missing READ_ONCE() to cmpxchg() loops prevent the
compiler from potentially generating incorrect code. This includes a
rather large change to the s390 specific hardware sampling code and
its current use of cmpxchg_double().
Do the fix now to get it out of the way of Peter Zijlstra's
cmpxchg128() work, and have something that can be backported. The
added new code includes a private 128 bit cmpxchg variant which will
be removed again after Peter's rework is available. Also note that
this 128 bit cmpxchg variant is used to implement 128 bit
READ_ONCE(), while strictly speaking it wouldn't be necessary, and
_READ_ONCE() should also be sufficient; even though it isn't obvious
for all converted locations that this is the case. Therefore use this
implementation for for the sake of clarity and consistency for now.
- Fix ipl report address handling to avoid kdump failures/hangs.
- Fix misuse of #(el)if in kernel decompressor.
- Define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36,
caused by the recently changed discard behaviour.
- Make sure _edata and _end symbols are always page aligned.
- The current header guard DEBUG_H in one of the s390 specific header
files is too generic and conflicts with the ath9k wireless driver.
Add an _ASM_S390_ prefix to the guard to make it unique.
- Update defconfigs.

Pull nolibc fixes from Paul McKenney:
- The fd_set structure was incorrectly defined as arrays of u32 instead
of long, which breaks BE64. Fix courtesy of Sven Schnelle.
- S_ISxxx macros were incorrectly testing the bits after applying them
instead of bitwise ANDing S_FMT with the value. Fix from Warner Losh.
- The mips code was randomly broken due to an unprotected "noreorder"
directive in the _start code that could prevent the assembler from
filling delayed slots. This in turn resulted in random other
instructions being placed into those slots. Fix courtesy of Willy
Tarreau.
- The current nolibc header layout refrains from including files that
are not explicitly included by the code using nolibc. Unfortunately,
this causes build failures when such files contain definitions that
are used (for example) by libgcc. Example definitions include raise()
and memset(), which are called by some architectures, but only at
certain optimization levels. Fix courtesy of Willy Tarreau.
- gcc 11.3 in ARM thumb2 mode at -O2 recognized a memset() construction
inside the memset() definition. The compiler replaced this
construction with a call to... memset(). Userland cannot be forced to
build with -ffreestanding, so an empty asm() statement was introduced
into the loop the loop in order to prevent the compiler from making
this unproductive transformation. Fix courtesy of Willy Tarreau.
- Most of the O_* macros were wrong on RISCV because their octal values
were coded as hexadecimal. This resulted in the getdents64() selftest
failing. Fix courtesy of Willy Tarreau.
This was tested on x86_64, i386, armv5, armv7, thumb1, thumb2, mips and
riscv, all at -O0, -Os and -O3.

output mode
acpi_get_and_request_gpiod() does not take a gpio_lookup_flags argument
specifying that the pins direction should be initialized to a specific
value.
This means that in some cases the pins might be left in input mode, causing
the gpiod_set() calls made to enable the clk / regulator to not work.
One example of this problem is the clk-enable GPIO for the ov01a1s sensor
on a Dell Latitude 9420 being left in input mode causing the clk to
never get enabled.
Explicitly set the direction of the pins to output to fix this.

Unlike keys where userspace only reacts to keypresses, userspace may act
on switches in both (0 and 1) of their positions.
For example if a SW_TABLET_MODE switch is registered then GNOME will not
automatically show the onscreen keyboard when a text field gets focus on
touchscreen devices when SW_TABLET_MODE reports 0 and when SW_TABLET_MODE
reports 1 libinput will block (filter out) builtin keyboard and touchpad
events.
So to avoid unwanted side-effects EV_SW type inputs should only be
registered if they are actually present, only register SW_CAMERA_LENS_COVER
if it is actually there.

It is possible that we (the host/kernel driver) receive command messages
that are not intended for us. Ignore those for now.
The whole story is a bit more complicated: It is possible to enable
debug output on SAM, which is sent via SSH command messages. By default
this output is sent to a debug connector, with its own target ID
(TID=0x03). It is possible to override the target of the debug output
and set it to the host/kernel driver. This, however, does not change the
original target ID of the message. Meaning, we receive messages with
TID=0x03 (debug) but expect to only receive messages with TID=0x00
(host).
The problem is that the different target ID also comes with a different
scope of request IDs. In particular, these do not follow the standard
event rules (i.e. do not fall into a set of small reserved values).
Therefore, current message handling interprets them as responses to
pending requests and tries to match them up via the request ID. However,
these debug output messages are not in fact responses, and therefore
this will at best fail to find the request and at worst pass on the
wrong data as response for a request.
Therefore ignore any command messages not intended for us (host) for
now. We can implement support for the debug messages once we have a
better understanding of them.
Note that this may also provide a bit more stability and avoid some
driver confusion in case any other targets want to talk to us in the
future, since we don't yet know what to do with those as well. A warning
for the dropped messages should suffice for now and also give us a
chance of discovering new targets if they come along without any
potential for bugs/instabilities.

If we have multiple requests waiting on the same target poll waitqueue,
then it's quite possible to get a request triggered and get disappointed
in not being able to make any progress with it. If we race in doing so,
we'll potentially leave the poll request on the internal tables, but
removed from the waitqueue. That means that any subsequent trigger of
the poll waitqueue will not kick that request into action, causing an
application to potentially wait for completion of a request that will
never happen.
Fix this by adding a new poll return state, IOU_POLL_REISSUE. Rather
than have complicated logic for how to re-arm a given type of request,
just punt it for a reissue.
While in there, move the 'ret' variable to the only section where it
gets used. This avoids confusion the scope of it.

used, resulting in Xen rejecting to accept the new CR3 value (the PGD
isn't pinned).
Fix that by adding the now missing call of paravirt_arch_dup_mmap() to
poking_init(). That call was previously done by dup_mm()->dup_mmap() and
it is a NOP for all cases but for Xen PV, where it is just doing the
pinning of the PGD.

when refreshing port id
Currently the driver sets the port invalid if one phy in the port is not
enabled, which may cause issues in expander situation. In directly attached
situation, if phy up doesn't occur in time when refreshing port id, the
port is incorrectly set to invalid which will also cause disk lost.
Therefore set a port invalid only if there are no devices attached to the
port.

Before the commit under Fixes the page would have been released
from the pool before the napi_alloc_skb() call, so normal page
freeing was fine (released page == no longer in the pool).
After the change we just mark the page for recycling so it's still
in the pool if the skb alloc fails, we need to recycle.
Same commit added the same bug in the new bnxt_rx_multi_page_skb().

Currently, it used old rss size to get current tc mode. As a result, the

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Make 'perf kmem' cope with the removal of some
kmem:kmem_cache_alloc_node and kmem:kmalloc_node in the
11e9734bcb6a7361 ("mm/slab_common: unify NUMA and UMA version of
tracepoints") commit, making sure it works with Linux >= 6.2 as well
as with older kernels where those tracepoints are present.
- Also make it handle the new "node" kmem:kmalloc and
kmem:kmem_cache_alloc tracepoint field introduced in that same
commit.
- Fix hardware tracing PMU address filter duplicate symbol selection,
that was preventing to match with static functions with the same name
present in different object files.
- Fix regression on what linux/types.h file gets used to build the "BPF
prologue" 'perf test' entry, the system one lacks the fmode_t
definition used in this test, so provide that type in the test
itself.
- Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the
user asks for linking with the libbpf package provided by the distro,
then it has to be >= 0.8.0. Using the libbpf supplied with the kernel
would be a fallback in that case.
- Fix the build when libbpf isn't available or explicitly disabled via
NO_LIBBPF=1.
- Don't try to install libtraceevent plugins as its not anymore in the
kernel sources and will thus always fail.

In commit 14243b387137a ("KVM: x86/xen: Add KVM_IRQ_ROUTING_XEN_EVTCHN
and event channel delivery") the clever version of me left some helpful
notes for those who would come after him:
/*
* For the irqfd workqueue, using the main kvm->lock mutex is
* fine since this function is invoked from kvm_set_irq() with
* no other lock held, no srcu. In future if it will be called
* directly from a vCPU thread (e.g. on hypercall for an IPI)
* then it may need to switch to using a leaf-node mutex for
* serializing the shared_info mapping.
*/
mutex_lock(&kvm->lock);
In commit 2fd6df2f2b47 ("KVM: x86/xen: intercept EVTCHNOP_send from guests")
the other version of me ran straight past that comment without reading it,
and introduced a potential deadlock by taking vcpu->mutex and kvm->lock
in the wrong order.
Solve this as originally suggested, by adding a leaf-node lock in the Xen
state rather than using kvm->lock for it.

is_mmconf_reserved() takes a "with_e820" parameter that only determines the
message logged if it finds the MMCONFIG region is reserved. Pass the
message directly, which will simplify a future patch that adds a new way of
looking for that reservation. No functional change intended.

Documentation/virt/kvm/locking.rst tells us that kvm->lock is taken outside
vcpu->mutex. But that doesn't actually happen very often; it's only in
some esoteric cases like migration with AMD SEV. This means that lockdep
usually doesn't notice, and doesn't do its job of keeping us honest.
Ensure that lockdep *always* knows about the ordering of these two locks,
by briefly taking vcpu->mutex in kvm_vm_ioctl_create_vcpu() while kvm->lock
is held.

The kvm_xen_update_runstate_guest() function can be called when the vCPU
is being scheduled out, from a preempt notifier. It *opportunistically*
updates the runstate area in the guest memory, if the gfn_to_pfn_cache
which caches the appropriate address is still valid.
If there is *contention* when it attempts to obtain gpc->lock, then
locking inside the priority inheritance checks may cause a deadlock.
Lockdep reports:
[13890.148997] Chain exists of:
&gpc->lock --> &p->pi_lock --> &rq->__lock
[13890.149002] Possible unsafe locking scenario:
[13890.149003] CPU0 CPU1
[13890.149004] ---- ----
[13890.149005] lock(&rq->__lock);
[13890.149007] lock(&p->pi_lock);
[13890.149009] lock(&rq->__lock);
[13890.149011] lock(&gpc->lock);
[13890.149013]
*** DEADLOCK ***
In the general case, if there's contention for a read lock on gpc->lock,
that's going to be because something else is either invalidating or
revalidating the cache. Either way, we've raced with seeing it in an
invalid state, in which case we would have aborted the opportunistic
update anyway.
So in the 'atomic' case when called from the preempt notifier, just
switch to using read_trylock() and avoid the PI handling altogether.

In commit 5ec3289b31 ("KVM: x86/xen: Compatibility fixes for shared runstate
area") we declared it safe to obtain two gfn_to_pfn_cache locks at the same
time:
/*
* The guest's runstate_info is split across two pages and we
* need to hold and validate both GPCs simultaneously. We can
* declare a lock ordering GPC1 > GPC2 because nothing else
* takes them more than one at a time.
*/
However, we forgot to tell lockdep. Do so, by setting a subclass on the
first lock before taking the second.
