With the current implementation, there are some cornercases where
a host fault would be treated as a guest fault, for example
when the sie instruction causes a program check. Therefore store
the gmap asce in ptregs, and use that to compare the primary asce
from the fault instead of matching instruction addresses.

When a program check, interrupt or machine check is triggered, the
PSW address is compared to a certain range of the sie64a() function
to figure out whether SIE was interrupted and a cleanup of SIE is
needed.
This doesn't work with kprobes: If kprobes probes an instruction, it
copies the instruction to the kprobes instruction page and overwrites the
original instruction with an undefind instruction (Opcode 00). When this
instruction is hit later, kprobes single-steps the instruction on the
kprobes_instruction page.
However, if this instruction is a relative branch instruction it will now
point to a different location in memory due to being moved to the kprobes
instruction page. If the new branch target points into sie64a() the kernel
assumes it interrupted SIE when processing the breakpoint and will crash
trying to access the SIE control block.
Instead of comparing the address, introduce a new CIF_SIE flag which
indicates whether SIE was interrupted.

In bind_evtchn_to_irq_chip() don't increment the refcnt of the event
channel blindly. In case the event channel is NOT refcounted, issue a
warning instead.
Add an additional safety net by doing the refcnt increment only if the
caller has specified IRQF_SHARED in the irqflags parameter.

When unbinding a user event channel, the related handler might be
called a last time in case the kernel was built with
CONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler.
Avoid that by adding an "unbinding" flag to struct user_event which
will short circuit the handler.

syzbot hit an assertion in copy up data loop which looks like it is
the result of a lower file whose size is being changed underneath
overlayfs.
This type of use case is documented to cause undefined behavior, so
returning EIO error for the copy up makes sense, but it should not be
causing a WARN_ON assertion.

The code that handles saved_cmdlines is split between the trace.c file and
the trace_sched_switch.c. There's some history to this. The
trace_sched_switch.c was originally created to handle the sched_switch
tracer that was deprecated due to sched_switch trace event making it
obsolete. But that file did not get deleted as it had some code to help
with saved_cmdlines. But trace.c has grown tremendously since then. Just
move all the saved_cmdlines code into trace_sched_switch.c as that's the
only reason that file still exists, and trace.c has gotten too big.
No functional changes.

The saved_cmdlines have three arrays for mapping PIDs to COMMs:
- map_pid_to_cmdline[]
- map_cmdline_to_pid[]
- saved_cmdlines
The map_pid_to_cmdline[] is PID_MAX_DEFAULT in size and holds the index
into the other arrays. The map_cmdline_to_pid[] is a mapping back to the
full pid as it can be larger than PID_MAX_DEFAULT. And the
saved_cmdlines[] just holds the COMMs associated to the pids.
Currently the map_pid_to_cmdline[] and saved_cmdlines[] are allocated
together (in reality the saved_cmdlines is just in the memory of the
rounding of the allocation of the structure as it is always allocated in
powers of two). The map_cmdline_to_pid[] array is allocated separately.
Since the rounding to a power of two is rather large (it allows for 8000
elements in saved_cmdlines), also include the map_cmdline_to_pid[] array.
(This drops it to 6000 by default, which is still plenty for most use
cases). This saves even more memory as the map_cmdline_to_pid[] array
doesn't need to be allocated.

Only the root "events" directory stores a dentry. There's no reason to
hold a dentry pointer for every eventfs_inode as it is never set except
for the root "events" eventfs_inode.
Create a eventfs_root_inode structure that holds the events_dir dentry.
The "events" eventfs_inode *is* special, let it have its own descriptor.

There's a couple of if statements in eventfs_root_lookup() that should
never be true. Instead of removing them, add WARN_ON_ONCE() around them.
One is a tracefs_inode not being for eventfs.
The other is a child being freed but still on the parent's children
list. When a child is freed, it is removed from the list under the
same mutex that is held during the iteration.

This reverts commit 1601cd53c7e3197181277326dbfc131d20a74e46.
This fix is applied globally to all devices, and it may change the
existing control names. When the devices are managed with the fixed
configuration like UCM, such control name mismatch may lead to
significant regressions.
For avoiding that kind of regression, we would need to apply such
changes conditionally, but it'd take time to settle down.
While the original fix is a good thing in general, in order to address
the regression, let's revert the change for now.

When a CPU enters into idle and deactivates itself from the timer
migration hierarchy without any global timer of its own to propagate,
the group event of that CPU is set to "ignore" and tmigr_update_events()
accordingly performs an early return without considering timers queued
by other CPUs.
If the hierarchy has a single level, and the CPU is the last one to
enter idle, it will ignore others' global timers, as in the following
layout:
[GRP0:0]
migrator = 0
active = 0
nextevt = T0i
/ \
0 1
active (T0i) idle (T1)
0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
[GRP0:0]
migrator = NONE
active = NONE
nextevt = T0i
/ \
0 1
idle (T0i) idle (T1)
1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1 and CPU 0 goes to idle with T1
unhandled.
This isn't proper to single level hierarchy though. A similar issue,
although slightly different, may arise on multi-level:
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T0:0i, T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = 0 migrator = NONE
active = 0 active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
active idle idle idle
0) CPU 0 is active thus its event is ignored (the letter 'i') and so are
upper levels' events. CPU 1 is idle and has the timer T1 enqueued.
CPU 2 also has a timer. The expiry order is T0 (ignored) < T1 < T2
[GRP1:0]
migrator = GRP0:0
active = GRP0:0
nextevt = T0:0i, T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = NONE migrator = NONE
active = NONE active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
idle idle idle idle
1) CPU 0 goes idle without global event queued. Therefore KTIME_MAX is
pushed as its next expiry and its own event kept as "ignore". As a result
tmigr_update_events() ignores T1. The change only propagated up to 1st
level so far.
[GRP1:0]
migrator = NONE
active = NONE
nextevt = T0:1
/ \
[GRP0:0] [GRP0:1]
migrator = NONE migrator = NONE
active = NONE active = NONE
nextevt = T0i nextevt = T2
/ \ / \
0 (T0i) 1 (T1) 2 (T2) 3
idle idle idle idle
2) The change now propagates up to the top. tmigr_update_events() finds
that the child event is ignored and thus removes it. The top level next
event is now T2 which is returned to CPU 0 as its next effective expiry
to take account for as the global idle migrator. However T1 has been
ignored along the way, leaving it unhandled.
Fix those issues with removing the buggy related early return. Ignored
child events must not prevent from evaluating the other events within
the same group.

Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

This is clear from the stack trace, we call nfs4_ff_layout_prepare_ds()
which could error out initializing the mirror_ds, and then we go to
clean it all up and our check is only for if (!mirror->mirror_ds). This
is inconsistent with the rest of the users of mirror_ds, which have
if (IS_ERR_OR_NULL(mirror_ds))
to keep from tripping over this exact scenario. Fix this up in
ff_layout_cancel_io() to make sure we don't panic when we get an error.
I also spot checked all the other instances of checking mirror_ds and we
appear to be doing the correct checks everywhere, only unconditionally
dereferencing mirror_ds when we know it would be valid.

This reverts commits 99101dda29e3186b1356b0dc4dbb835c02c71ac9 and
b80b701d5a67d07f4df4a21e09cb31f6bc1feeca.
Linus reports that the sysreg reserved bit checks in KVM have led to
build failures, arising from commit fdd867fe9b32 ("arm64/sysreg: Add
register fields for ID_AA64DFR1_EL1") giving meaning to fields that were
previously RES0.
Of course, this is a genuine issue, since KVM's sysreg emulation depends
heavily on the definition of reserved fields. But at this point the
build breakage is far more offensive, and the right course of action is
to revert and retry later.
All of these build-time assertions were on by default before
commit 99101dda29e3 ("KVM: arm64: Make build-time check of RES0/RES1
bits optional"), so deliberately revert it all atomically to avoid
introducing further breakage of bisection.

When a lock is waiting for a reply for a remote operation, and recovery
interrupts this "waiters" state, the remote operation is voided by the
recovery, and no reply will be processed. The lkb waiters state for the
remote operation is forcibly reset/cleared, so that the lock operation
can be restarted after recovery. Improve the comments describing this.

Pull VFIO updates from Alex Williamson:
- Add warning in unlikely case that device is not captured with
driver_override (Kunwu Chan)
- Error handling improvements in mlx5-vfio-pci to detect firmware
tracking object error states, logging of firmware error syndrom, and
releasing of firmware resources in aborted migration sequence (Yishai
Hadas)
- Correct an un-alphabetized VFIO MAINTAINERS entry (Alex Williamson)
- Make the mdev_bus_type const and also make the class struct const for
a couple of the vfio-mdev sample drivers (Ricardo B. Marliere)
- Addition of a new vfio-pci variant driver for the GPU of NVIDIA's
Grace-Hopper superchip. During initialization of the chip-to-chip
interconnect in this hardware module, the PCI BARs of the device
become unused in favor of a faster, coherent mechanism for exposing
device memory. This driver primarily changes the VFIO representation
of the device to masquerade this coherent aperture to replace the
physical PCI BARs for userspace drivers. This also incorporates use
of a new vma flag allowing KVM to use write combining attributes for
uncached device memory (Ankit Agrawal)
- Reset fixes and cleanups for the pds-vfio-pci driver. Save and
restore files were previously leaked if the device didn't pass
through an error state, this is resolved and later re-fixed to
prevent access to the now freed files. Reset handling is also
refactored to remove the complicated deferred reset mechanism (Brett
Creeley)
- Remove some references to pl330 in the vfio-platform amba driver
(Geert Uytterhoeven)
- Remove twice redundant and ugly code to unpin incidental pins of the
zero-page (Alex Williamson)
- Deferred reset logic is also removed from the hisi-acc-vfio-pci
driver as a simplification (Shameer Kolothum)
- Enforce that mlx5-vfio-pci devices must support PRE_COPY and remove
resulting unnecessary code. There is no device firmware that has been
available publicly without this support (Yishai Hadas)
- Switch over to using the .remove_new callback for vfio-platform in
support of the broader transition for a void remove function (Uwe
Kleine-König)
- Resolve multiple issues in interrupt code for VFIO bus drivers that
allow calling eventfd_signal() on a NULL context. This also remove a
potential race in INTx setup on certain hardware for vfio-pci, races
with various mechanisms to mask INTx, and leaked virqfds in
vfio-platform (Alex Williamson)

Pull kvm updates from Paolo Bonzini:
"S390:
- Changes to FPU handling came in via the main s390 pull request
- Only deliver to the guest the SCLP events that userspace has
requested
- More virtual vs physical address fixes (only a cleanup since
virtual and physical address spaces are currently the same)
- Fix selftests undefined behavior
x86:
- Fix a restriction that the guest can't program a PMU event whose
encoding matches an architectural event that isn't included in the
guest CPUID. The enumeration of an architectural event only says
that if a CPU supports an architectural event, then the event can
be programmed *using the architectural encoding*. The enumeration
does NOT say anything about the encoding when the CPU doesn't
report support the event *in general*. It might support it, and it
might support it using the same encoding that made it into the
architectural PMU spec
- Fix a variety of bugs in KVM's emulation of RDPMC (more details on
individual commits) and add a selftest to verify KVM correctly
emulates RDMPC, counter availability, and a variety of other
PMC-related behaviors that depend on guest CPUID and therefore are
easier to validate with selftests than with custom guests (aka
kvm-unit-tests)
- Zero out PMU state on AMD if the virtual PMU is disabled, it does
not cause any bug but it wastes time in various cases where KVM
would check if a PMC event needs to be synthesized
- Optimize triggering of emulated events, with a nice ~10%
performance improvement in VM-Exit microbenchmarks when a vPMU is
exposed to the guest
- Tighten the check for "PMI in guest" to reduce false positives if
an NMI arrives in the host while KVM is handling an IRQ VM-Exit
- Fix a bug where KVM would report stale/bogus exit qualification
information when exiting to userspace with an internal error exit
code
- Add a VMX flag in /proc/cpuinfo to report 5-level EPT support
- Rework TDP MMU root unload, free, and alloc to run with mmu_lock
held for read, e.g. to avoid serializing vCPUs when userspace
deletes a memslot
- Tear down TDP MMU page tables at 4KiB granularity (used to be
1GiB). KVM doesn't support yielding in the middle of processing a
zap, and 1GiB granularity resulted in multi-millisecond lags that
are quite impolite for CONFIG_PREEMPT kernels
- Allocate write-tracking metadata on-demand to avoid the memory
overhead when a kernel is built with i915 virtualization support
but the workloads use neither shadow paging nor i915 virtualization
- Explicitly initialize a variety of on-stack variables in the
emulator that triggered KMSAN false positives
- Fix the debugregs ABI for 32-bit KVM
- Rework the "force immediate exit" code so that vendor code
ultimately decides how and when to force the exit, which allowed
some optimization for both Intel and AMD
- Fix a long-standing bug where kvm_has_noapic_vcpu could be left
elevated if vCPU creation ultimately failed, causing extra
unnecessary work
- Cleanup the logic for checking if the currently loaded vCPU is
in-kernel
- Harden against underflowing the active mmu_notifier invalidation
count, so that "bad" invalidations (usually due to bugs elsehwere
in the kernel) are detected earlier and are less likely to hang the
kernel
x86 Xen emulation:
- Overlay pages can now be cached based on host virtual address,
instead of guest physical addresses. This removes the need to
reconfigure and invalidate the cache if the guest changes the gpa
but the underlying host virtual address remains the same
- When possible, use a single host TSC value when computing the
deadline for Xen timers in order to improve the accuracy of the
timer emulation
- Inject pending upcall events when the vCPU software-enables its
APIC to fix a bug where an upcall can be lost (and to follow Xen's
behavior)
- Fall back to the slow path instead of warning if "fast" IRQ
delivery of Xen events fails, e.g. if the guest has aliased xAPIC
IDs
RISC-V:
- Support exception and interrupt handling in selftests
- New self test for RISC-V architectural timer (Sstc extension)
- New extension support (Ztso, Zacas)
- Support userspace emulation of random number seed CSRs
ARM:
- Infrastructure for building KVM's trap configuration based on the
architectural features (or lack thereof) advertised in the VM's ID
registers
- Support for mapping vfio-pci BARs as Normal-NC (vaguely similar to
x86's WC) at stage-2, improving the performance of interacting with
assigned devices that can tolerate it
- Conversion of KVM's representation of LPIs to an xarray, utilized
to address serialization some of the serialization on the LPI
injection path
- Support for _architectural_ VHE-only systems, advertised through
the absence of FEAT_E2H0 in the CPU's ID register
- Miscellaneous cleanups, fixes, and spelling corrections to KVM and
selftests
LoongArch:
- Set reserved bits as zero in CPUCFG
- Start SW timer only when vcpu is blocking
- Do not restart SW timer when it is expired
- Remove unnecessary CSR register saving during enter guest
- Misc cleanups and fixes as usual
Generic:
- Clean up Kconfig by removing CONFIG_HAVE_KVM, which was basically
always true on all architectures except MIPS (where Kconfig
determines the available depending on CPU capabilities). It is
replaced either by an architecture-dependent symbol for MIPS, and
IS_ENABLED(CONFIG_KVM) everywhere else
- Factor common "select" statements in common code instead of
requiring each architecture to specify it
- Remove thoroughly obsolete APIs from the uapi headers
- Move architecture-dependent stuff to uapi/asm/kvm.h
- Always flush the async page fault workqueue when a work item is
being removed, especially during vCPU destruction, to ensure that
there are no workers running in KVM code when all references to
KVM-the-module are gone, i.e. to prevent a very unlikely
use-after-free if kvm.ko is unloaded
- Grab a reference to the VM's mm_struct in the async #PF worker
itself instead of gifting the worker a reference, so that there's
no need to remember to *conditionally* clean up after the worker
Selftests:
- Reduce boilerplate especially when utilize selftest TAP
infrastructure
- Add basic smoke tests for SEV and SEV-ES, along with a pile of
library support for handling private/encrypted/protected memory
- Fix benign bugs where tests neglect to close() guest_memfd files"

improvements
- Add a stub for_each_property_of_node() for !OF
- Adjust the printk levels on some messages

Pull MTD updates from Miquel Raynal:
"MTD:
- The Carillo Ranch driver has been removed
- Top level mtd bindings have received a couple of improvements
(references, selects)
- The ssfdc driver received few minor adjustments
- The usual load of misc/small improvements and fixes
Raw NAND:
- The main series brought is an update of the Broadcom support to
support all BCMBCA SoCs and their specificity (ECC, write
protection, configuration straps), plus a few misc fixes and
changes in the main driver. Device tree updates are also part of
this PR, initially because of a misunderstanding on my side.
- The STM32_FMC2 controller driver is also upgraded to properly
support MP1 and MP25 SoCs.
- A new compatible is added for an Atmel flavor.
- Among all these feature changes, there is as well a load of
continuous read related fixes, avoiding more corner conditions and
clarifying the logic. Finally a few miscellaneous fixes are made to
the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller
driver, as well as final one in the Hynix vendor driver.
SPI-NAND:
- The ESMT support has been extended to match 5 bytes ID to avoid
collisions. Winbond support on its side receives support for
W25N04KV chips.
SPI NOR:
- SPI NOR gets the non uniform erase code cleaned. We stopped using
bitmasks for erase types and flags, and instead introduced
dedicated members. We then passed the SPI NOR erase map to MTD.
Users can now determine the erase regions and make informed
decisions on partitions size.
- An optional interrupt property is now described in the bindings"

Recovery changes for the iMX and iMX-LPI2C are now utilizing the
generic i2c support.
The Cadence driver now supports system suspend and resume.
The hisi, mpc, sh_mobile, and npcm drivers have undergone some
cleanups and improvements. Meanwhile, Uwe continues his work on
converting the "remove" callback to become a void function.
The pca954x mux driver now supports additional configurations, such as
isolating faulty channels and flushing stuck buses, among others.
