KVM selftests changes for 6.9:
- Add macros to reduce the amount of boilerplate code needed to write "simple"
selftests, and to utilize selftest TAP infrastructure, which is especially
beneficial for KVM selftests with multiple testcases.
- 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.

KVM/riscv changes for 6.9
- Exception and interrupt handling for selftests
- Sstc (aka arch_timer) selftest
- Forward seed CSR access to KVM userspace
- Ztso extension support for Guest/VM
- Zacas extension support for Guest/VM

KVM/arm64 updates for 6.9
- 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

KVM GUEST_MEMFD fixes for 6.8:
- Make KVM_MEM_GUEST_MEMFD mutually exclusive with KVM_MEM_READONLY to
avoid creating ABI that KVM can't sanely support.
- Update documentation for KVM_SW_PROTECTED_VM to make it abundantly
clear that such VMs are purely a development and testing vehicle, and
come with zero guarantees.
- Limit KVM_SW_PROTECTED_VM guests to the TDP MMU, as the long term plan
is to support confidential VMs with deterministic private memory (SNP
and TDX) only in the TDP MMU.
- Fix a bug in a GUEST_MEMFD negative test that resulted in false passes
when verifying that KVM_MEM_GUEST_MEMFD memslots can't be dirty logged.

* kvm-arm64/vfio-normal-nc:
: Normal-NC support for vfio-pci @ stage-2, courtesy of Ankit Agrawal
:
: KVM's policy to date has been that any and all MMIO mapping at stage-2
: is treated as Device-nGnRE. This is primarily done due to concerns of
: the guest triggering uncontainable failures in the system if they manage
: to tickle the device / memory system the wrong way, though this is
: unnecessarily restrictive for devices that can be reasoned as 'safe'.
:
: Unsurprisingly, the Device-* mapping can really hurt the performance of
: assigned devices that can handle Gathering, and can be an outright
: correctness issue if the guest driver does unaligned accesses.
:
: Rather than opening the floodgates to the full ecosystem of devices that
: can be exposed to VMs, take the conservative approach and allow PCI
: devices to be mapped as Normal-NC since it has been determined to be
: 'safe'.
vfio: Convey kvm that the vfio-pci device is wc safe
KVM: arm64: Set io memory s2 pte as normalnc for vfio pci device
mm: Introduce new flag to indicate wc safe
KVM: arm64: Introduce new flag for non-cacheable IO memory

: VM configuration enforcement, courtesy of Marc Zyngier
:
: Userspace has gained the ability to control the features visible

* kvm-arm64/feat_e2h0:
: Support for FEAT_E2H0, courtesy of Marc Zyngier
:
: As described in the cover letter:
:
: Since ARMv8.1, the architecture has grown the VHE feature, which makes
: EL2 a superset of EL1. With ARMv9.5 (and retroactively allowed from
: ARMv8.1), the architecture allows implementations to have VHE as the
: *only* implemented behaviour, meaning that HCR_EL2.E2H can be
: implemented as RES1. As a follow-up, HCR_EL2.NV1 can also be
: implemented as RES0, making the VHE-ness of the architecture
: recursive.
:
: This series adds support for detecting the architectural feature of E2H
: being RES1, leveraging the existing infrastructure for handling
: out-of-spec CPUs that are VHE-only. Additionally, the (incomplete) NV
: infrastructure in KVM is updated to enforce E2H=1 for guest hypervisors
: on implementations that do not support NV1.
arm64: cpufeatures: Fix FEAT_NV check when checking for FEAT_NV1
arm64: cpufeatures: Only check for NV1 if NV is present
arm64: cpufeatures: Add missing ID_AA64MMFR4_EL1 to __read_sysreg_by_encoding()
KVM: arm64: Handle Apple M2 as not having HCR_EL2.NV1 implemented

KVM: arm64: Expose ID_AA64MMFR4_EL1 to guests

LoongArch VCPUs have their own separate HW timers. SW timer is to wake
up blocked vcpu thread, rather than HW timer emulation. When blocking
vcpu scheduled out, SW timer is used to wakeup blocked vcpu thread and
injects timer interrupt. It does not care about whether guest timer is
in period mode or oneshot mode, and SW timer needs not to be restarted
since vcpu has been woken.
This patch does not restart SW timer when it is expired.

SW timer is enabled when vcpu thread is scheduled out, and it is to wake
up vcpu from blocked queue. If vcpu thread is scheduled out but is not
blocked, such as it is preempted by other threads, it is not necessary
to enable SW timer. Since vcpu thread is still on running queue if it is
preempted and SW timer is only to wake up vcpu on blocking queue, so SW
timer is not useful in this situation.
This patch enables SW timer only when vcpu is scheduled out and is
blocking.

Pull firewire fixes from Takashi Sakamoto:
"A workaround to suppress the continuous bus resets in the case that
older devices are connected to the modern 1394 OHCI hardware and
devices
In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
However, it is well-known that the solution is not necessarily
effective in the mixing environment that both IEEE 1394-1995 PHY and
IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2
of IEEE 1394a-2000.
The current implementation of firewire stack schedules the short bus
reset when attempting to resolve the mismatch of gap count in the
certain generation of bus topology. It can cause the continuous bus
reset in the issued environment.
The workaround simply uses the long bus reset instead of the short bus
reset. It is desirable to detect whether the issued environment or
not. However, the way to access PHY registers from remote note is
firstly defined in IEEE 1394a-2000, thus it is not available in the
case"

In commit 19416123ab3e ("block: define 'struct bvec_iter' as packed"),
what we need is to save the 4byte padding, and avoid `bio` to spread on
one extra cache line.
It is enough to define it as '__packed __aligned(4)', as '__packed'
alone means byte aligned, and can cause compiler to generate horrible
code on architectures that don't support unaligned access in case that
bvec_iter is embedded in other structures.

huge vmalloc/vmap regions
