Merge tag 's390-6.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

- Standardize on the __ASSEMBLER__ macro that is provided by GCC and
Clang compilers and replace __ASSEMBLY__ with __ASSEMBLER__ in both
uapi and non-uapi headers

- Explicitly include <linux/export.h> in architecture and driver files
which contain an EXPORT_SYMBOL() and remove the include from the
files which do not contain the EXPORT_SYMBOL()

- Use the full title of "z/Architecture Principles of Operation" manual
and the name of a section where facility bits are listed

- Use -D__DISABLE_EXPORTS for files in arch/s390/boot to avoid
unnecessary slowing down of the build and confusing external kABI
tools that process symtypes data

- Print additional unrecoverable machine check information to make the
root cause analysis easier

- Move cmpxchg_user_key() handling to uaccess library code, since the
generated code is large anyway and there is no benefit if it is
inlined

- Fix a problem when cmpxchg_user_key() is executing a code with a
non-default key: if a system is IPL-ed with "LOAD NORMAL", and the
previous system used storage keys where the fetch-protection bit was
set for some pages, and the cmpxchg_user_key() is located within such
page, a protection exception happens

- Either the external call or emergency signal order is used to send an
IPI to a remote CPU. Use the external order only, since it is at
least as good and sometimes even better, than the emergency signal

- In case of an early crash the early program check handler prints more
or less random value of the last breaking event address, since it is
not initialized properly. Copy the last breaking event address from
the lowcore to pt_regs to address this

- During STP synchronization check udelay() can not be used, since the
first CPU modifies tod_clock_base and get_tod_clock_monotonic() might
return a non-monotonic time. Instead, busy-loop on other CPUs, while
the the first CPU actually handles the synchronization operation

- When debugging the early kernel boot using QEMU with the -S flag and
GDB attached, skip the decompressor and start directly in kernel

- Rename PAI Crypto event 4210 according to z16 and z17 "z/Architecture
Principles of Operation" manual

- Remove the in-kernel time steering support in favour of the new s390
PTP driver, which allows the kernel clock steered more precisely

- Remove a possible false-positive warning in pte_free_defer(), which
could be triggered in a valid case KVM guest process is initializing

- Unconditionally adv

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
"Generic:

- Use memdup_array_user() to harden against overflow.

- Unconditionally advertise KVM_CAP_DEVICE_CTRL for all
architectures.

- Clean up Kconfigs that all KVM architectures were selecting

- New functionality around "guest_memfd", a new userspace API that
creates an anonymous file and returns a file descriptor that refers
to it. guest_memfd files are bound to their owning virtual machine,
cannot be mapped, read, or written by userspace, and cannot be
resized. guest_memfd files do however support PUNCH_HOLE, which can
be used to switch a memory area between guest_memfd and regular
anonymous memory.

- New ioctl KVM_SET_MEMORY_ATTRIBUTES allowing userspace to specify
per-page attributes for a given page of guest memory; right now the
only attribute is whether the guest expects to access memory via
guest_memfd or not, which in Confidential SVMs backed by SEV-SNP,
TDX or ARM64 pKVM is checked by firmware or hypervisor that
guarantees confidentiality (AMD PSP, Intel TDX module, or EL2 in
the case of pKVM).

x86:

- Support for "software-protected VMs" that can use the new
guest_memfd and page attributes infrastructure. This is mostly
useful for testing, since there is no pKVM-like infrastructure to
provide a meaningfully reduced TCB.

- Fix a relatively benign off-by-one error when splitting huge pages
during CLEAR_DIRTY_LOG.

- Fix a bug where KVM could incorrectly test-and-clear dirty bits in
non-leaf TDP MMU SPTEs if a racing thread replaces a huge SPTE with
a non-huge SPTE.

- Use more generic lockdep assertions in paths that don't actually
care about whether the caller is a reader or a writer.

- let Xen guests opt out of having PV clock reported as "based on a
stable TSC", because some of them don't expect the "TSC stable" bit
(added to the pvclock ABI by KVM, but never set by Xen) to be set.

- Revert a bogus, made-up nested SVM consistency check for
TLB_CONTROL.

- Advertise flush-by-ASID support for nSVM unconditionally, as KVM
always flushes on nested transitions, i.e. always satisfies flush
requests. This allows running bleeding edge versions of VMware
Workstation on top of KVM.

- Sanity check that the CPU supports flush-by-ASID when enabling SEV
support.

- On AMD machines with vNMI, always rely on hardware instead of
intercepting IRET in some cases to detect unmasking of NMIs

- Support for virtualizing Linear Address Masking (LAM)

- Fix a variety of vPMU bugs where KVM fail to stop/reset counters
and other state prior to refreshing the vPMU model.

- Fix a double-overflow PMU bug by tracking emulated counter events
using a dedicated field instead of snapshotting the "previous"
counter. If the hardware PMC count triggers overflow that is
recognized in the same VM-Exit that KVM manually bumps an event
count, KVM would pend PMIs for both the hardware-triggered overflow
and for KVM-triggered overflow.

- Turn off KVM_WERROR by default for all configs so that it's not
inadvertantly enabled by non-KVM developers, which can be
problematic for subsystems that require no regressions for W=1
builds.

- Advertise all of the host-supported CPUID bits that enumerate
IA32_SPEC_CTRL "features".

- Don't force a masterclock update when a vCPU synchronizes to the
current TSC generation, as updating the masterclock can cause
kvmclock's time to "jump" unexpectedly, e.g. when userspace
hotplugs a pre-created vCPU.

- Use RIP-relative address to read kvm_rebooting in the VM-Enter
fault paths, partly as a super minor optimization, but mostly to
make KVM play nice with position independent executable builds.

- Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on
CONFIG_HYPERV as a minor optimization, and to self-document the
code.

- Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV
"emulation" at build time.

ARM64:

- LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB base
granule sizes. Branch shared with the arm64 tree.

- Large Fine-Grained Trap rework, bringing some sanity to the
feature, although there is more to come. This comes with a prefix
branch shared with the arm64 tree.

- Some additional Nested Virtualization groundwork, mostly
introducing the NV2 VNCR support and retargetting the NV support to
that version of the architecture.

- A small set of vgic fixes and associated cleanups.

Loongarch:

- Optimization for memslot hugepage checking

- Cleanup and fix some HW/SW timer issues

- Add LSX/LASX (128bit/256bit SIMD) support

RISC-V:

- KVM_GET_REG_LIST improvement for vector registers

- Generate ISA extension reg_list using macros in get-reg-list
selftest

- Support for reporting steal time along with selftest

s390:

- Bugfixes

Selftests:

- Fix an annoying goof where the NX hugepage test prints out garbage
instead of the magic token needed to run the test.

- Fix build errors when a header is delete/moved due to a missing
flag in the Makefile.

- Detect if KVM bugged/killed a selftest's VM and print out a helpful
message instead of complaining that a random ioctl() failed.

- Annotate the guest printf/assert helpers with __printf(), and fix
the various bugs that were lurking due to lack of said annotation"
