* Clean up vCPU targets, always returning generic v8 as the preferred target
* Trap forwarding infrastructure for nested virtualization (used for traps
that are taken from an L2 guest and are needed by the L1 hypervisor)
* FEAT_TLBIRANGE support to only invalidate specific ranges of addresses
when collapsing a table PTE to a block PTE. This avoids that the guest
refills the TLBs again for addresses that aren't covered by the table PTE.
* Fix vPMU issues related to handling of PMUver.
* Don't unnecessary align non-stack allocations in the EL2 VA space
* Drop HCR_VIRT_EXCP_MASK, which was never used...
* Don't use smp_processor_id() in kvm_arch_vcpu_load(),
but the cpu parameter instead
* Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
* Remove prototypes without implementations
RISC-V:
* Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
* Added ONE_REG interface for SATP mode
* Added ONE_REG interface to enable/disable multiple ISA extensions
* Improved error codes returned by ONE_REG interfaces
* Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
* Added get-reg-list selftest for KVM RISC-V
s390:
* PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
* Guest debug fixes (Ilya)
x86:
* Clean up KVM's handling of Intel architectural events
* Intel bugfixes
* Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug
registers and generate/handle #DBs
* Clean up LBR virtualization code
* Fix a bug where KVM fails to set the target pCPU during an IRTE update
* Fix fatal bugs in SEV-ES intrahost migration
* Fix a bug where the recent (architecturally correct) change to reinject
#BP and skip INT3 broke SEV guests (can't decode INT3 to skip it)
* Retry APIC map recalculation if a vCPU is added/enabled
* Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
"emergency disabling" behavior to KVM actually being loaded, and move all of
the logic within KVM
* Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
ratio MSR cannot diverge from the default when TSC scaling is disabled
up related code
* Add a framework to allow "caching" feature flags so that KVM can check if
the guest can use a feature without needing to search guest CPUID
* Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
* Fix KVM's handling of !visible guest roots to avoid premature triple fault
injection
* Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
that is needed by external users (currently only KVMGT), and fix a variety
of issues in the process
This last item had a silly one-character bug in the topic branch that
was sent to me. Because it caused pretty bad selftest failures in
some configurations, I decided to squash in the fix. So, while the
exact commit ids haven't been in linux-next, the code has (from the
kvm-x86 tree).
Generic:
* Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
action specific data without needing to constantly update the main handlers.
* Drop unused function declarations
Selftests:
* Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
* Add support for printf() in guest code and covert all guest asserts to use
printf-based reporting
* Clean up the PMU event filter test and add new testcases
* Include x86 selftests in the KVM x86 MAINTAINERS entry
